Using Tiva C Series TM4C123GH with Energia 1.6.10E18, Win7 platform. TivaC is connected by USB, of course . I really need to be able to set Serial2.begin(38400) to implement Even Parity [8E1, instead of 8N1] because of the fixed hardware that is being connected. There is a patch posted already for the MSP430G2553; I'm pretty sure the register arrangement for the Tiva C is vastly different. There's a register in the TM4C123GH at 0x4000:E02C (E000 offset 0x2C) which contains the command word for that UART (parity select, number of bits, enable FIFO, ESP, PENable) that needs to be modif

Hi , I am interfacing MSP430F5529 and SIM900A using energia software. I have tried the code using Arduino Uno before and it seemed to work fine. However when I try the same with msp430 , there is no output on the serial monitor. Few days back I came to know that there is a voltage mismatch between the msp430 output and sim900 input and as suggested by few members of the thread , I am supposed to use a voltage translator to convert the 3.3V output of the Msp430 board and then apply it to sim900A module. They recommended Rs232 for this purpose . I want to know the connection that'll be requ

Hi experts!! I'm a beginner and working on CC3200 LP along with Energia IDE. I'm working on a simple project where I've an external device which has RS485 o/p and I need to fetch the values in specified addr location in that device to CC3200 LP. My doubts are #1) we have external module that has device ID+parameter Address and we need to transmit the value in LP through UART, here I'm not sure how to use the UART function to specifically target device+address and return/get the same.... #2) what I'm looking/exploring is that in above example (UART code which Andy shared here
