SKR E3 DIP with TMC5160 (pin PB15 is reserved for spi2) #2072

Closed r15ch13 closed 5 years ago

r15ch13 commented 5 years ago

I was trying to use the SKR E3 DIP with TMC5160 drivers. I copied the generic-bigtreetech-skr-mini-e3.cfg and changed the PINs according to the sheet from BIGTREETECH and also referencing the pins_BIGTREE_SKR_E3_DIP.h from Marlin 2.x.

But after running sudo service klipper restart it shows the following error: pin PB15 is reserved for spi2

I then changed it to another PIN (for testing) and got the same error for PB14 and PB13. According to https://www.klipper3d.org/stm32f1.html these PINs are used for SPI or as general I/O.

Digging around the source revealed: https://github.com/KevinOConnor/klipper/blob/1e8582e3f6cb13d85f06c740d7f79824c15a88be/src/stm32/spi.c#L17-L18 Is it possible to disable spi2?

Setting spi_bus to spi1 seems to work.

[tmc5160 stepper_x]
cs_pin = PC10
spi_bus = spi1

Running STEPPER_BUZZ STEPPER=stepper_x does nothing though...

I setup the E3 dip with tmc2130 in spi mode. I used SPI3 pins

[tmc2130 stepper_x] cs_pin: PC10 spi_software_sclk_pin: PB3 spi_software_mosi_pin: PB5 spi_software_miso_pin: PB4

[tmc2130 stepper_y] cs_pin: PC11 spi_software_sclk_pin: PB3 spi_software_mosi_pin: PB5 spi_software_miso_pin: PB4

[tmc2130 stepper_z] cs_pin: PC12 spi_software_sclk_pin: PB3 spi_software_mosi_pin: PB5 spi_software_miso_pin: PB4

[tmc2130 extruder] cs_pin: PD2 spi_software_sclk_pin: PB3 spi_software_mosi_pin: PB5 spi_software_miso_pin: PB4

My reference for these pins came from https://github.com/bigtreetech/BIGTREETECH-SKR-E3-DIP-V1.0/blob/master/Hardware/SKR%20E3-DIP-PIN.pdf

That worked! Thank you! 👍
