"stdout" tab does not appear
Hello, I am Mr. Hahn, Man Je
1. I have a TMS320C6416T DSK board. Yesterday I tried to activate the DSK board with C code. however "stdout" tab of Output Window did not appear after "Build All". There were several "printf" function to show execution results. so again I loaded "out" extension file to execute, but the "alarm message" appeared and said the program is not valid in the case, and "stdout" tab did not appear. there were no compile and execution errers
what is wrong with my program
2. I have to design RF circuit with TMS320C6xxx. AD/DA conversion is diffcuit and plays key rolls in RF circuit design. however I couldn't find any AD/DA conversion chip supporting RF circuits. Commonly AD/DA conversion use Parerel Port but TMSC6000 only support a serial data transfer. I can not find this solution. Do you have any solution? Please let me know
It difficult for me to guess, what's wrong with stdout. If your project uses DSP/BIOS, consider its log feature and LOG_printf().
As to the second question, C6416T actually has parallel interfaces, namely EMIF. The question is whether you can glue your AD/DA to those interfaces.
In my company we found another solution. Even with power of C64x we could not do all required processing, like filtering, FFT, so we use FPGA as companion coprocessor. FPGA is interfaced with AD/DAs, performs buffering and several processing steps. Then FPGA is connected to DSP using EMIF.
I cannot tell, if that solution good for you, I don't know anything about your design. Consider it as possible variant.
Which version of CCS are you using? You seem to have more than one problem with the program since you get different results different times that you try to load the .out file. It also appears you are expecting the program to run automatically; is that correct?
Your first question should be posted to the Code Composer Forum. Do you need more information for your second question?
