  1. If you appreciate late 90s vintage PCs you might be interested in this one. I decided to build a Pentium II machine on which I can play my favourite games from those times. Magic Carpet (Bullfrog Productions) is one of them, but it needs a joystick. I had good quality USB joysticks, but those games need old analog gameport-based controllers that are serviced by the sound cards of the time. This new project acts as a USB Host and provides the analog output that emulates a 4 axis + 4 button game controller. the prototype works absolutely great, it takes about 0.6ms to read data fr
  2. Hello, I would like to interface USB push notification board (bought recently) https://store.ncd.io/product/4-channel-push-notification-contact-closure-input-over-usb/ with MSP430 and interface multi sensors in such a way that whenever the sensor range is disrupted then actuator assigned to sensor will be switch on and this message will be sent on smart phones, I am new to this kid work and also if this thing will successful then I would like to make the actuators like rely board function with these king push notification any suggestion regarding making these kind solution through embedded s
  3. Hi! It's my first time using MSP430 and I'm a little bit lost . I want to connect a barcode scanner module with the MSP430. In order to do that, I need an USB port extra. I know that Arduino has a USB Host shield, but MSP430 doesn't have any shields, does it? So, how can I do it? Is there any way to use the USB Shield of Arduino for the MSP430? Thanks!
  4. I'm trying to bring up a CLI/Makefile based toolset under Ubuntu. Ubuntu version 17.04 MSPDebug version 0.24 My two Launchpads are both MSP-EXP430G2, Rev1.5, and are about three years old. One has a 2553 chip and the other is a 2452. Result of 'mspdebug --usb-list' includes: Devices on bus 001: 001:010 0451:f432 eZ430-RF2500 [serial: FEFF467AF9CB2548] Running mspdebug gives: randy@corvette: mspdebug/0.24$ ./mspdebug -U '001:010' rf2500 MSPDebug version 0.24 - debugging tool for MSP430 MCUs Copyright (C) 2009-2016 Daniel Beer <dlbeer@gmail.com> This is
  5. Hi I wonder if anybody can give a newbie some advice. I just started using my MSP430G2553 today. Was working great through USB and getting to grips with the basics using energia 101E0017 (I couldnt get R18 working). Then decided to disconnect the USB cable and power at 3.6V through the 3 pin header (Vcc GND, GND) was working good until I knocked the board and a cable must have shorted something, as the board will no longer power through Vcc but will when using the USB cable. Powering through the Vcc on the 3 pin header or the 10 pin header on the left side of the board I get 3.6 volt

  8. I know I haven't finished off my desk clock project just yet, But I've been requested to design a new GPS logging device for my sisters Beagle Club, The basic idea is that a sent is placed with a guy that forms a path, the GPS logger is taken along also. They then attach the device to a beagle (using some kind of vest, I think). And let them follow the scent. Post event they extract the GPS data from the logger and overlay both tracks in google earth. They have one unit that has been working well for them, developed by a previous club member. It consists of off the shelf c
  9. Hi there, first of all sorry but I am a greenhorn in programming a ┬ÁController :-/ I set myself a new goal that I program a tiny tool to measurer timings of a self made shutter electronic for a camera. For this I would like to send a String by pushing button1 at my MSP430G2553 LaunchPad. The string should be sending via USB connection to PC and again to another USB Port. The hardware at the end of the second USB Port will drive a solenoid. The primary purpose is to measure the delay between sending at the LaunchPad and receiving the driver signal of the solenoid driver.
  10. Hi I purchased a TUSB3410PDK EVM kit. Also, I downloaded a USB-Serial port interface code from a open source site. By now i understand that the TUSB3410 boots out of a ROM code initially and then loads the code from EEPROM and passes control to the EEPROM code. The issue is if I just execute this code below.it does not toggle P3_3 pin why?. The other question is am i supposed to re-enumerate with the code that I got from opensource ... And if so does anyone here have experience with this open source bootcode... Note, I have got it compiled using SDCC and have tried putting the
  11. For those of you attempting to build USB devices I put together some Launchpad examples as well as a lab type walkthrough of how to create custom devices (mainly HID) Included 1) Examples ported to the Launchpad - Mouse, Keyboard, Composite 2) Updated HID header file with additional device and usage types 3) A new device type called usbdhidcustom - This allows you to make new devices with minimal code changes 4) A complete document in lab type format where you build a volume control device, a gamepad and a keyboard + mouse 5) Completed projects to go with the labs
  12. Hello, in my project I want to use the MSP430G2553 as a master which communicates with another device via USCI_A0 UART mode. Is it possible to program the MSP430G2553 via the other modes, e.g. USCI_B0 SPI or USCI_B0 I2C respectively, without the use of a programmer? Are there any tutorials regarding on how to write a bootloader for the MSP430? Cheers, Tim Torpedo
  13. Hi everyone, TLDNR: How do I set up MIDI descriptors for MIDI over USB so that I can get my PC to recognize my F5510 as a class-compliant MIDI device, either using the TI USB Dev package, api, and descriptor tool, or manually? I'm working on my first MSP430 project and hoping to get some help setting up the USB interface in CCS. I'm working with an MSP430F5510 on a custom board and trying to set it up so that it's recognized as a class-compliant midi device on the PC - then I will send midi messages to the PC to control music programs, etc. I'm stuck on where to start for configuring the U
  14. For those in the US: Fry's has 5V 1A USB chargers from Belkin on sale for 30 cents a piece! Perfect for powering the odd electronics project. http://www.frys.com/product/6517763 According to this test and teardown, it seems to be living up to its spec: http://www.eevblog.com/forum/reviews/teardown-$0-30-usb-power-supply-at-fry%27s/msg671559/ The catch? The connector on the USB cable is for obsolete iProducts. So you even get a solid USB cable that can be cut up without regrets. My local Fry's in Renton, WA still had a few hundred on stock at 3pm today. I don't think they wil
  15. I'm currently doing a project on MSP430F5638. I want to implement USB on it. I got the code from TI website,(I am running the M2_SDCardReader example that came with version 4_20_00 of the USB Developers Package.) but while running this code I am facing some problems. If I run the code I can see unknown device(after calling the function usb_conncet) in my system for a moment, then its disappearing. I used descriptor tool to assign the VID and PID as mentioned in the guide provided by TI. how can i solve this problems..????? Do you have any suggestions?
  16. I recent completed the prototype of my LoginNFC project. It's a combination of MSP430 acting as a USB keyboard (and CDC serial for configuration) and a TRF7970A NFC reader. The prototype was done with a F5529 LaunchPad and TRF7970A Booster - along with a ferrite antenna to improve the read range. It's working well and I did a small write-up here: https://0xfred.wordpress.com/2015/01/14/nfc-login-version-1-0/ However, I don't really feel it's complete until I've got it off the dev board and made a decent PCB. This is my first double-sided PCB, first time with USB, first time with LQFP a
  17. The Examples Guide: MSP430 USB API Stack (contained within the MSP430 USB Developers Package) states that cdcSendDataInBackground alternates between bufferX and bufferY. I stared at the code but still cannot figure out how the program flow does the bufferX-then-bufferY thing. Any thoughts?
  18. I'm in the middle of a project using the f5529 launchpad and Energia. I'm trying to use both the USB and the I2C port at the same time. I can initialize the USB and see it enumerate in the windows device manager and I can read/write to it and it works properly. But as soon as I try to enable the I2C port using the USCI_B1 the USB dies and can no longer be read or written to. The example codes in Energia work for both the USB examples and for the TMP006 example, so the harware is OK. But trying to get them both to play at the same time is a nogo. What am I missing? #include <
  19. Greetings, I am currently working on a personal project using Tiva Launchpad together with Eclipse Kepler IDE and GNU ARM Embedded Tools (gcc version 4.8.2). Last week my efforts were focused on making the "usb_dev_serial" example (Tivaware 2.0.1.11577) work with that development setup (also i'm using it all on Windows 8). So far, a simple I2C master + button interrupt + LED toggling example I've made with this development configuration is working OK. When the USB module was added ("usb_dev_serial" skeleton added to my project), some compiling issues arised, but got fixed after I put "
  20. Hello everyone, FIrst - its not the permission issue of not having a proper udev rule. I am on Debian Wheezy with all the msp related packages installed from the official repos - including mspdebug. But after I connect the launchpad and give: mspdebug rf2500 I get usbutil: unable to find a device matching 0451:f432 My computer is not detecting the board. The output of lsusb is: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0020 Intel Corp.

  21. I'm calling in the MSP430 USB specialists. On Rev A of my standalone AIS Receiver board, I connect DP/DM (D+/D-) backwards to the MSP43F5508. After I realized the error, I cut the traces and patched it up with two short wires. Unfortunately the device is still not enumerated by the host. I use TI's USB library. USB_setup() completes successfully, but USB_connectionState() stays in the enumerating state forever while nothing happens on the PC. Could it be, that I killed the USB data inputs by having DP and DM connected the wrong way around? Any other suggestions on how to debug
  22. Hi, I am planning to build a logic analyser using my Tiva-C launchpad. I have seen a logic analyser using the SUMP protocol but it uses the USB CDC (serail port) to transfer data. http://www.fischl.de...aris_launchpad/ I need a better sampling rate for my GPIO. My plan is to copy the contents of GPIO data register using DMA into the USB FIFO. Then use some custome device driver in USB to transfer data to PC instead of using USB CDC class drivers.There is a similar example for STM32(but for a different application) http://www.st.com/st.../CD00256689.pdf How to find out the sampli
  23. Okay, so I found out from my previous post that the output value from the ADC can be accessed through pui32ADC0Value...now, im trying to send that data via USB device mode in Tiva, however, my concerns are will my code work? And if it works, how do I access that data via MatLab. Thanks Once again, credits to the maker of the ADC code. #include <stdbool.h> #include <stdint.h> #include "inc/hw_memmap.h" #include "driverlib/adc.h" #include "driverlib/gpio.h" #include "driverlib/sysctl.h" #include "driverlib/adc.h" #include "inc/hw_types.h" #include "driverlib/debug.h"

    Hi, I recently found a ADC code in the forums. I plan to input it with a signal, but I dont know where to test the output. Here's the code, credits to the maker. #include <stdbool.h> #include <stdint.h> #include "inc/hw_memmap.h" #include "driverlib/adc.h" #include "driverlib/gpio.h" #include "driverlib/sysctl.h" #include "driverlib/adc.h" #include "inc/hw_types.h" #include "driverlib/debug.h" main(void) { uint32_t pui32ADC0Value[1]; SysCtlClockSet(SYSCTL_SYSDIV_10 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN| SYSCTL_XTAL_16MHZ); //Set clock at 40 Mhz , Sometimes //ADC may not
  25. Hey guys. I recently got a Launch pad -- MSP430G2 board ( Rev B ) [only the board and the USB cable from a friend]. I downloaded Energia for my Mac running OS X 10.9. [maverics]. Though the Power LED lights up, the board is not recognised by the IDE. I don't know if the problem is with the board, the cable or the IDE. Though the board was detected for a short period of time and I was able to just uplaod the Blink sketch into it. Now when I connect to a USB power or my MAC, led1 just keeps blinking. I am unable to program it. I hope you guys can help me spot the problem so that I ca
