Hello !
This is my first post here. I'm asking if it is possible to drive a standard 16x2 lcd via PCF8574 I2C I/O expander with PBP code directly.
I've done V and A meter with 2 channel ADC in PIC12F675 (0-50V, 0-5A) and I was thinking to output measured data on the LCD. The problem is the small number of I/O pins on the PicMicro. My idea is to use the I2C port expander. This type of controlling the LCD I saw on the net but was implemented in C programming language.
Any help will be apriciated !
