Recently, I need to run an FFT program on my ARM platform, and it needs to be very fast. Because it is a double-precision floating-point operation, my chip is S3C2440, which does not have a hard float...
When I read the program in the book, I have never seen any interrupt for ADC. In the AD sampling program, the interrupt for DMA0 is enabled, but the interrupt for ADC is not enabled. 1. What does the ...
I have a proposal to organize some experts in the forum to draw a 4-layer to 8-layer circuit board, and draw from the schematic to the PCB, with full transparency, so that everyone can participate in ...
