lcd + pcf8574 I2C adaptor
Posted: Wed Jan 31, 2018 8:51 pm
hi there.
i am building my own customised setup and can now happily connect to cheap ebay stm32f407 "diy more" board.
I have found an I2C 20x4 lcd in my box of bits, and there is a pcf8574 option in TS. Are there particular outputs I should use for SCL/SDA?
