  1. Hi , I am using MSP430FR4133LP , in energia the GPIO pins are predefined in the pins_energia.h for MSP430FR4133 LP based on the silkscreen on the board. I using this MSP430FR4133 chip for another project and in that i am not using a LCD so i thought that i can also use LCD pins as GPIO. For this purpose i need to add the pins in the pins_energia.h but i am not able to crack it. Can anyone help me with this ....? if i try to use any other pins other than the defined ones (say P2_2) ... it throws an error as " P2_2 not defined in the scope" // Pin names based on the silkscreen
  2. So, this is partly for me, and partly for others who need a refresher, or just do not know how. But I will be making several post here over time on how to write very simply code, to do one thing, or another. These, used in conjunction with a shell script could be very useful / flexible. After several long talks with many people, including some here on these very forums. I've decided that using C, to communicate with hardware, or hardware interfaces is best as can be for many situations. However, when you need to run several tools all at once, and have output formatted in some fashion, or easil
  3. Hello, We are planning to do work on CC3200MOD LaunchpadXL. So, CC3200 GPIO/UART/ADC Energia IDE based header files can compatible in CC3200MOD? I also some confusion regarding Energia IDE based header file.Please mention below description. If you see pin_energia.h file in one array initialize for CC3200 LaunchXL like this, const uint16_t digital_pin_to_pin_num[] = { NOT_A_PIN, /* dummy */ NOT_A_PIN, /* 1 - 3.3V */ PIN_58, /* 2 - GPIO_03 */ <- pins_energia.h (CC3200) *Note : In CC3200MOD PIN_58 = GND PIN_04, /* 3 - GPIO_
  4. In my project, I use a few basic macros for GPIO. The goal is, that I can easily redefine pin assignment in a central location without compromising performance or code size. The macros (gpiomacros.h): // MSP430 gpio macros #define GPIO_SEL(port) P ## port ## SEL #define GPIO_DIR(port) P ## port ## DIR #define GPIO_OUT(port) P ## port ## OUT #define GPIO_IN(port) P ## port ## IN #define GPIO_IS_INPUT(port,pin) { GPIO_SEL(port) &= ~(pin); GPIO_DIR(port) &= ~(pin); } #define GPIO_IS_OUTPUT(port,pin) { GPIO_SEL(port) &= ~(pin); GPIO_DIR(port) |= (pin); } #define GPIO_IS_PERIPHER
  5. Hi, Previously I was using CC3200 launch pad for developing my module. But now I want to use GPIOs and control leds etc on launch pad. When using normally, I used digitalWrite(pinnumber,1); But now I want to control led etc using GPIO. How to accomplish that in Energia. I have seen peripheral library for cc3200 , but I am not able to use it. Kindly help asap.
  6. I am using the current sensor HO 10-P with my TM4C123 launchpad board. Essentially I have to connect the Vout pin to a GPIO, configure the GPIO as an ADC pin and then configure the ADC controller to read the Vout from the sensor. I will connect the Vout to PE2 (which is AIN2 and also a GPIO). Wondering how to configure this GPIO as an ADC and then read it? Can you show a sample code snippet?
  7. I'm getting very frustrated with this CC3200MOD, and the CC3200 in general. First it started with the A0 analog channel always reading 4096 but now on to some GPIO problems. This should be fairly straight forward but apparently they make everything difficult, so I don't know what to say. I have made a custom PCB for using the CC3200MOD. Its supposed to read the 4 ADCs, 3 for accelerometer, which is working great, 1 for an analog microphone, which isn't working at all, but I've given up on it and going to just mux with one of the 3 working ones. Now I have 3 LEDs on the board for general LE
  8. Hi, I'm getting to grips with a Launchpad ek-tmc123gxl board, and so far it looks amazing. However I have hit a snag which is pretty painful. Consider the following code: #include <stdbool.h> #include <stdint.h> #include "inc/hw_gpio.h" #include "inc/hw_memmap.h" #include "inc/hw_sysctl.h" #include "inc/hw_types.h" #include "driverlib/gpio.h" #include "driverlib/pin_map.h" #include "driverlib/rom.h" #include "driverlib/rom_map.h" #include "driverlib/sysctl.h" void setup(void); #define delay(x) SysCtlDelay((SysCtlClockGet() / 3000000) * x) uint8_t sequence_1[16] = { 0x4
  9. Hello, For a certain experiment I need to do, I need to generate some pulses, as fast as possible. For beginning I need a square wave, basically, so I wrote the following code: (which does not work, according to my scope) #include <Energia.h> #include "inc/lm4f120h5qr.h" #include "driverlib/gpio.h" void setup() { GPIOPadConfigSet(GPIO_PORTA_BASE, 0xff, GPIO_STRENGTH_2MA, GPIO_PIN_TYPE_STD); GPIODirModeSet(GPIO_PORTA_BASE, 0xff, GPIO_DIR_MODE_OUT); } void loop() { GPIOPinWrite(GPIO_PORTA_BASE, GPIO_PIN_6, LOW); GPIOPinWrite(GPIO_PORTA_BASE, GPIO_PIN_6, HIGH); }
  10. Hi all, I have made a couple of MSP430 Tutorials and thought I would share the links here: ADC tutorial and example code I did this one awhile ago and just covers the ADC with 3 example codes, multiple channels, multiple reads etc http://coder-tronics.com/msp430-adc-tutorial/ Timer tutorial and example code Only posted recently and covers both timers on the MSP430G2253, again with 3 examples PWM, interrupts etc. http://coder-tronics.com/msp430-timer-tutorial/ Programming tutorial covering the GPIO and peripheral registers I found this all a little confusing when I started
  11. Hi, I got my BBB few days ago and decided to do something to help the BBB community. I found that accessing GPIO and Analog Interface is difficult (without bonescript) when using Linux and accessing them inside a C/C++ application, so I decided to write an arduino like interface for GPIO and Analog. I have plans to add serial, I2C and PWM later. There might be bugs so if you find any let me know. Its very easy to use, there is a test example for both adc and gpio. I need feedback so that it can be improved and more functionalities can be added. Git Hub Link for the Project: https://github.co
  12. I have designed my very first circuit, it is a simple non-inverting amplifier. Its purpose is to take line-level audio (1.6v) and double it (3.2v) so that the TIva ADC can process the audio. It seems to work, as in when I am not playing music, AIN0 returns values around 0. Where as when I play music AIN0 reports much larger numbers. The problem however is that the numbers seem random, and don't seem to be following the music in anyway I can tell. I am wondering if I have done something silly with my circuit or do I require a low-pass filter or something to remove noise?? I have tr
  13. I follow your forum for a while now. I’m starting digital artist working on IR project at the moment. I was hoping you could advice me a bit as you are expert for Beagle Bone. I have design music application in Unity 3D. It reacts to 24 different keyboard inputs. Now I was hoping to be able to control it remotely. I was trying to make I arts installation that would use remote controllers sending signals to receivers connected to different GPIOS on the Beagle Bone. Receiver would get binary IR signal and send it to Beagle Bone GPIO. Beagle Bone would change it to key input and send it to
  14. hello I'm playing with my stellaris launchpad, I got openocd 0.7.0 working and I'm trying to write my own GPIO init code. I wrote this generic routine to initialize the uart pins. I've defined several flags, and according to the value of these flags, I'm attempting to write the appropriate GPIO configuration registers. For that, I'm using the AHB access method, writing to BASE+OFF where OFF is the offset of the required register (eg #define LM4F_GPIO_GPIODIR 0x400 // GPIO Direction) BASE is 0x40058000 + (port<<16) I'm using this because it's easier to com
  15. Is there any significatn advantage of using ROM_GPIOPinRead over GPIOPinRead? I want to read the status of a pin, GPIOPinRead(GPIO_PORTA_BASE,GPIO_PIN_5) I am hoping to use this method to read the status. What is the return value? Where can i find the documentation which contains aboout GPIOPinRead? Thank you.
