I have a bold idea, can I use blank ROM to add FFT function, I want to realize the function of spectrum analyzer, in addition, add FIFO buffer IC between ADC and FPGA part, I can do soldering technology. Thank you. I have put my ADC 9288 100 to work properly at 100Mhz, the question is how to overclock. Everyone speeds me up. I bought ST LINK V8 and I wo n’t use it.
