I continue to try (unsuccessfully) to connect an rmt output to a gpio AND to a pcnt input. I am still confused by Chapter 4 of the TRM even though some have tried to explain it to me. It would help if I could find the c code for gpio_matrix_in and gpio_matrix_out. I have ...
gpio_matrix_out(PIN_SMI_MDIO, EMAC_MDO_O_IDX, 0, 0); gpio_matrix_in(PIN_SMI_MDIO, EMAC_MDI_I_IDX, 0); set the Direction BIT of the GPIO in this example MDIO is in and output https://esp32.com/viewtopic.php?f=12&p=6422#p6401 ? we need to set the BIT again for input...
