WebFeb 21, 2024 · The STM32 is operating at 180MHz, and the SPI CLK is at ~30MHz. You can see that once the SPI initiates it is very fast, but the time to initiate the next SPI read is taking too long (~6us) which is limiting the rate at which I can read from the ADC. I understand that this approach will only read ADC-0A, and not ADC-0B simultaneously. WebJul 11, 2024 · As Embedded Guy pointed out, STM32 SPI peripherals have a FIFO buffer which can be filled with junk due to software bugs (on the slave or master side), spurious clock edges caused by noise, etc. Unfortunately, there is no explicit 'clear fifo' command that can be issued from within the peripheral itself.
