I'm using a FRDM-K64 board. I need to sample the ADC at 1.2 MHz.
I have use the PDB timer to program hardware interrupt. The program works but
the interruption function takes almost half of the CPU time (47%), and I need more time
for the data computing in the main program.
Is there a better way to do, for sampling ADC at high speed. I was thinking to an hardware FIFO
where the data conversion of the ADC would be stored.
Thanks for your help
