  1. Hello, I've been trying to run an example called "graphicstest" from adafruit's ST7735 library on a TFT display using an MSP432. My problem is that, for some reason, software SPI works but not hardware SPI. The example "graphicstest" has an option to switch to software SPI by setting the MOSI and SCK pins to whatever i want and when i do that it works, the program does it's little test, but the problem with that is that it runs VERY slow so i kinda need this to work at its intended speed by using hardware SPI. if i hook up MOSI pin to P1.6 and SCK to P1.5 on my MSP432, nothing h
  2. After joining this forum over 3 years ago I thought it overdue that I say hello and contribute something that I hope you will find useful. Attached is a picture of simple booster packs that I make. But are they really a "booster pack"? Hmmm. Debatable! They are cheap and easy to make and I have made 5 of them. I use them all the time because the whole of each project, including the MSP430, is attached to the booster pack. This means I can switch between projects without re-wiring, I can change the model of MSP430 in seconds and I only need one Launchpad. You can see from the pic

    Noise in ADC

    Hi, I have a non-profit (Smoky Mountain Scientific, smokymtsci.com) that develops and sells low cost instruments for science education. One of our instruments incorporates a Tiva-C launchpad that outputs a pwm voltage and measures voltage and current passed in electrochemical reactions. I recently purchased a fairly large batch of Tiva launchpads from Mouser and I am having trouble with noise in the analog read channels for about 1/4th of the boards. We have been building and selling these instruments for a couple of years now and have never had this problem before. To test the boards, I
  4. Hi. I'm new to 43oh. My team is building a platform for the breadboard for software developers. It allows you to configure prototypes without wires or other components. How? Connect the controller board to your breadboard and PC. Connect channels to IO pins in the user interface. The user interface will interact with the hardware and implement your configuration on a breadboard via a programmable switch matrix, thereby replacing wires. Then, if you want the user interface to interact with the ADC onboard the controller board: Connect the GPIO channel to the ADC channel on the same IO pin.
  5. Hello folks, I recently wrote a library that performs an application requiring using 5 timer modules, leaving the 6th out. I looked through some of energia's source code afterwords in case there would be any conflicts, and I noticed that at least the analog write function utilizes a timer to generate its pwm. I might be able to bypass that since I leave 1 timer open for other usage. Does anyone know what timers energia needs to use in its libraries that would cause conflicts?
  6. WS2812 driver for Tiva is available here
  7. I wrote program of ADC in tiva c launchpad..I am using PB5 pin(AIN11) for analog input..But How to connect Sensor (voltage input-3.3 voltage input )to launchpad...My sensor has 2 wire Vin,Gnd.....Should i have to connect Vin to PB5 and Gnd of sensor to GND pin of Launchpad..

    AshimaCore

    Hy for all forum members! I want to show you a newly developed ARM device for which we raise funds (for the prototype, and manufacturing) Some words about the AshimaCore : AshimaCore The AshimaCore is designed to be a very flexible, programmable inertial measurement unit - with a whole bunch of onboard computing capability. You don't need any propriety tools to program it - we recommend gcc, gmake, and dfu-util - just plug it in to your labtop via usb and you're ready to hack! This isn't Arduino, it's a far more powerful embedded development tool. We've packaged the board in a
  9. Here is a code library for a 7seg display/led/button module available cheaply on dealextreme. Code works well and I've found it useful, though I've had some trouble integrating it into other projects.
