Which PINs have PWM?
Is there something on the schematic that shows which pins have PWM capability or do they all have PWM? I have SKR 1.4 Turbo
I did some poking around and found that the following pins have PWM - Verified PWM works - Z-Stop P1_27 PWRDET P1_00 I2C_SCA1 P0_00 I2C_SCL1 P0_01 SPI P0_26 (top left) (closest to power and CPU) (appears to not be used by SPI) NEOPIX P1_24 PROBE P0_10
Did not test but expected to work: SERVO P2_02
Pins I tested but bad things happened (lost access to the on board SD card): SPI_SCK1 P0_07 (top middle) DO NOT USE
Pins I did not test because bad things happened on related pins: SPI_MISO1 P0_08 (top right) DO NOT USE SPI_MOSI1 P0_09 (bottom middle) DO NOT USE
Pins I expected to work but did not work for PWM or GPIO - Maybe I need to change more in the config? E1_Det P1_25 E0_Det P1_26 Y-Stop P1_28 X-Stop P1_29
Pins I did not test (because I need them) but may work: E1 Stepper pins, E1 Enable P1_16 E1 Step P1_15 E1 Dir P1_14
TFT Pins TFT RX0 P0_03 TFT TX0 P0_02
Wifi Pins Wifi TX3 P4_28 Wifi RX3 P4_29
