All io stop work when I2S is actived.

[RDS356]

I'm trying to use my self made board with GRBLhall. This board works perfectly in grbl_esp32, Fluidnc, etc.
My problem is, when I active the I2S(with shift register) all IO not work more. Look my config, i commented the lines(*) and all ports like M8, M7, M3, stepper enable works , but if I uncommented no one works.

Default is to use I2S for all output signals. Spindle and coolant signals can be switched to normal GPIO, see here.

I have not made it possible to use normal GPIO for motor enable signals, this could be added to driver.c in the same way as for spindle and coolant.

[RDS356]

Unfortunately doesn't work. when I compile with I2S the GPIO.15 stay ever high, regardless if this GPIO.15 is configured or not.

[terjeio]

Try with the latest version and these #defines in your map file:

#define I2S_SPINDLE 0
#define I2S_COOLANT 0
#define I2S_STEPPER_ENA 0

[RDS356]

I tried like you said, but still the same problem. When I associet these I2S ports and compile the GPIO.15 go to high and nothing more work. Replacing the I2S ports by GPIO_NUM_ all ports GPIO work.(M3, M7, M8,INPUTS).

[terjeio]

Did you update to the latest version? $I should report driver version 230416.

[RDS356]

Yes, I did.

$i
[VER:1.1f.20230411:]

I updated merging these files manually;
main/CMakeLists.txt
main/driver.c
main/driver.h
main/embedded/index.html.gz
main/mks_tinybee_1_0_map.h

On time, what this line means ?
#define I2S_OUT_PIN_BASE 64

[terjeio]

Try this driver:

driver.zip

On time, what this line means ?
#define I2S_OUT_PIN_BASE 64

It is a pin number offset to distinguish I2S pins from GPIO pins.

Hi..
Work fine.
Thank you very much.
