Hello, My company is recently migrating from CCS2.2 to CCS 3.1. I'm opening the CCS 2.2 projects in CCS 3.1, lettting CCS 3.1 convert the CDB file and then saving the project. One of the projects I migrated is not working. When the project is compiled using 3.1 The behavior is like that of an errant pointer, we've debugged with an emulator and watched the execution "go out into the wo...

I am just trying to use the "insert graph" function in CCS v3.3. The thing I don't understand about the output graph is that it gives scaled y-axis value. For argument's sake, I have put in a value of 4096 in address 0x8000 with a data buffer size of 128. I would be expecting to get a straight constant line at the value of 4096 (decimal number). However, I am getting this straight line with a valu...

Hi... New here and to the CCS world in general. I am working on a project to convert some MSP430 assembly code to "C" using Code Composer. The structure of the system requires me to have a 2-byte version number at the very beginning of the FLASH image -- something that is very easy to do in assembly: org 8000h dw 0214h ; version 2.20 org 8002h code goes h...

When I check the values, I get the following numbers: {2.4, 1.2354, 10.02, -1.456, -4.235, 3.426, -3.876, -9.235, 1....

I recently got all of my code to work properly and display normal behavior in the watch window, so I'm beginning to listen to the output of the program. As I expected would probably happen, the output is not correct. To run simple testing, I place the following lines at the beginning of my program for(i = 0; i < dwNumNewSamples; i++){ while (!PEP5416_AIC23_read16(hCodec, &buffer[i]));
