Open frankdunn opened 5 years ago

frankdunn commented 5 years ago

Hi , I am looking at using tmc2130 drivers with a 3 axis engraver . Would it conflict with any hardware if I add a hardware spi port on the bluepill ? The hardware pins does not conflict with any pins I need : /*SPI1 GPIO Configuration
PB3 ------> SPI1_SCK PB4 ------> SPI1_MISO PB5 ------> SPI1_MOSI / pc13 , pc14 , pc15 would be chip select for x , y , z .
