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?

Re: lcd + pcf8574 I2C adaptor
A contributor has made some progress on this a while back and I never have used this setup. I am unable to help with LCD+I2C, I can use your help documenting when you get this working

PS: see lcd_HD44780.cpp - the code around i2cMasterTransmit is commented out looks like this requires code changes
