M1_CS pin
Which pin is used for CS? the diagram only include RX, EN, DIR, STEP, DIAG but not for CS. Help!
Cs pin... Chip select pin is used for spi mode. So if you want to use spi you will need to pull from somwhere else. With uart mode you dont need that pin
You need Uart_Pin which is same as CS pin in spi mode and assigning rx pin as uart pin is not working .
