There has been some additions made to standard gcodes available.
- M122 P200 - This gives an output of pin assignments for the configured board
- M150 - X2 has been added for the Neopixels. It should be used instead of X1. This is only applicable to this LPC/STM32 port.
- M308 - “thermocouple-max6675” has been added as an additional sensor type. This is only applicable to this LPC/STM32 port.
M350 - For many of the drivers used on the supported board, the microstepping is controlled by hardware (e.g. by installing certain jumpers). This is only supported by TMC22XX and TMC5160 drivers set in UART/SPI mode.
M915 - Stall detection is now supported on the SKR v1.3, SKR v1.4, SKR 2, SKR E3 Turbo, SKR GTR, SKR Pro, SKR-RRF-E3, Fly-CDY, Fly-E3, Fly-E3-Pro and MKS SGen L v1 and v2 when using TMC2209, TMC2226 or TMC5160 drivers
