SOLVED: Question about I2S and I2C about esp32 HOT 3 CLOSED

I use the I2S pin also for the other signals (flood, mist ,spindle enable and spindle direction) but not work.

Did you change driver.c for that? Try DIGITAL_OUT/DIGITAL_IN instead of gpio_set_level/gpio_get_level for those pins.

Now I will try to connect this signals with I2C IOEXPAND (I order the adapter), and I would like to change the default I2C pins (GPIO 22 (SCL) and GPIO 21 (SDA)) with GPIO 4 (SCL) and GPIO 0 (SDA), it's possible?

You can try? Here is how it is configured in a board map:

// Define I2C port/pins
#define I2C_PORT                I2C_NUM_1
#define I2C_SDA                 GPIO_NUM_21
#define I2C_SCL                 GPIO_NUM_22
#define I2C_CLOCK               100000

I change driver.c and work.
Thank's Terje Io

i got a question, not related to the ticket. how can i single control these pins for another project... makerbase-mks/MKS-TinyBee#113
