Hi, I'm new to MSP430, I'm using a MSP430G2553 in a project and need help with an in depth understanding of programming the ADC10 inputs of the MCU. I'm using a potentiometer in order to light one of 3 LEDs. For example, LED1 lights up when input voltage is 1V or less, LED2 lights up between 1V and 2V and LED3 lights up when the input voltage is greater than or equal to 2V. I have attached my code below but I am not clear on how to read, convert and store a voltage so that I can use the IF statements to light the respective LEDs. #include <msp430g2553.h> void indicator_LED

I am working on the MSP430G2553 using I2C and Serial libraries. I am playing right now to try to understand the usage of the libraries. I have an I2C slave that I am trying to control how much data gets returned when a read is executed. Using the serial interface I can increase the size that is sent over the I2C but I can't reduce the size even though the variable passed to Wire.write shows it has reduced. Slave code: #include <Wire.h> #define MY_ADDR 2 #define ERR_RQST_MSB 0xF0 ///< First byte sent when request hasn't been preceded by a value #define ERR_RQST_LSB -
Hello, I am using example code of energia Pfatfs library named "PFatFsfileTest". This program reads "T_READ.txt" file from sd card properly. But It can't write string "Hello world" 10 times to the file "T_WRITE.txt" into sd card. Instead, it just writes only "H". I am posting the original code of file below: /*----------------------------------------------------------------------*/ /* Petit FatFs sample project for generic uC (C)ChaN, 2010 */ /*----------------------------------------------------------------------*/ /* ported to Energia */ /* copy the two files t_read.t
