Logic analyzer on ESP32 for self-diagnostics

[blade77]

Thanks a lot! Static 40 MHz sample rate seems to work fine for my use case. I would also like to send packages at 40 MHz as a kind of automation. I will try to figure out how.

I had to do the following changes for slave mode (using external clock) on ESP32:

Code: Select all

gpio_matrix_in(SD_CLOCK_PIN, I2S0I_WS_IN_IDX, false);

Code: Select all

I2SX.conf.rx_slave_mod = 1;

Code: Select all

//    logic_analyzer_ll_set_clock(sample_rate);

It seems to capture sd interface signals stable with 20 MHz clock.

I'm glad it worked out for you ))
