SOLVED: Question about I2S and I2C

[ennio64]

Hallo I'm trying to create map file for a MKS Tinybee board. I assigned GPIO pin at X_lim, Y_lim, Z_lim, A_lim, B_lim, Probe, Feed Hold and Cycle Start and work well. I use the I2S pin for the stepper motor (XYZAB) and all work well. I use the I2S pin also for the other signals (flood, mist ,spindle enable and spindle direction) but not work. I think, but I'm not sure, that I2S is dedicated only to stepper. 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? Every answer is appreciated. Thank's

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

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