Trouble for Compiling

[anawwaaf]

I have a 3 axis CNC machine for milling and I want to use a Raspberry Pico RP2040 as a controller.
I've done a git clone

git clone --recurse-submodules https://github.com/grblHAL/RP2040.git

and I have edited my_machine.h and added my_machine_map.h

edited section in my_machine.h :

#define BOARD_MY_MACHINE                              //in line 33
#define SPINDLE0_ENABLE         SPINDLE_PWM0          //in line 48
#define EEPROM_ENABLE          32                     //in line 78

this is the my_machine_map.h based on generic_map.h :

to set the compatibility level,

do I just need to change this #define COMPATIBILITY_LEVEL 0 in config.h ?

do I need to add my board to the driver.json file?

do I just need to change this #define COMPATIBILITY_LEVEL 0 in config.h ?

Only if you are using a sender that does not like the grblHAL extensions.

do I need to add my board to the driver.json file?

No, this file is only used by the Web Builder.

[terjeio]

20/21 should work too if you remove the Aux in 1 conflict.

[anawwaaf]

You have a pin conflict: [PIN:21,Aux in 1,P1]

yeah, thanks for reminding me,

I tried to correct it, and I can use I2C on pins 20 and 21 too

[anawwaaf]

what are the differents between

#define AUXINPUT1_PIN 28

#if PROBE_ENABLE
#define PROBE_PIN AUXINPUT1_PIN
#endif

And

#if PROBE_ENABLE
#define PROBE_PIN 28
#endif

[anawwaaf]

and if I try

#define AUXINPUT0_PIN 21

#if I2C_ENABLE
#define I2C_PORT 0
#define I2C_SDA 20
#define I2C_SCL AUXINPUT0_PIN
#endif

and the result is that GRBL doesn't work, if I change the GRBL settings from MDI, GRBL doesn't respond

but if I define #define I2C_SCL 21 and remove the #define AUXINPUT0_PIN 21, GRBL works fine

#if I2C_ENABLE
#define I2C_PORT 0
#define I2C_SDA 20
#define I2C_SCL 21
#endif

[terjeio]

The difference is that the former leaves the pin as an aux input if the probe input is not enabled.

Allocating pins from the aux pool is not made available for pins connected to peripherals like I2C or SPI since they are typically routed to on-board devices.
