Hi, this is Sunny again.
As I went on developing my ASK tranceiver, I found that I put several indicator in the SCTL, and want to monitor their status on Host PC. But the problem come:
1. If the SCTL is driven by high speed configuration clock, it is OK.
2. if the SCTL is driven by low speed ADC/DAC clock, I can NOT observe any change of the indicators on the Host PC.
I looked at input/output example, it says there might be communication problem if putting indicators in low speed SCTL. So is it the reason?
Also, I noticed that when sharing
control signals between different SCTLs, the example uses global variable. So is it recommended to use global variable in such case? Can I use local variable?
Thanks!
