Hi all, I have a custom board with 5 ADSP-21062 processors. 4 of the processors receive A/D data on their serial ports. The serial ports are configured for receiving two channels of 32-bit data. 2 of the processors (ID=2 and 4) work fine with no problems. The other two

Hello all, the 65L has two serial ports, 0 and 1. Each serial port consist of two seperate data lines, A and B, making a total of four serial I/O lines. I seem to remember that when a serial port was operated in multichannel mode, it could not operate both A and B

I am using 2189m EZ-kit which has a dual Analog Front End AD73322. It is used as a 2 channel ADC and DAC. Does anyone has any experience handling the program that communicate between AD73322 and DSP through SPORT? I tried the Talkthrough.asm demo program but it was only for 1 c
