An example is a host CPU on a main embedded board using I 2 C to communicate with user interface devices located on a separate front panel board. Do you want to subscribe in order to receive notifications regarding "PIC16F877A microcontroller LCD example with CCS PIC C" changes. Their are several serial communication standards like RS232, SPI, I2C etc. PIC16F877A also have separate registers for I2C. C Code Example, Including PRINTF to the LCD. Because I used to use MPASM. There is an LCD I2C master library included in the Arduino IDE. 3V microcontroller like lpc1768, lpc2148 or interfacing 3. In this example we connect an RGB led to PORT C 0 - 2 of our PIC16F877A. This driver acts as an SPI or I2C master and uses FPGA digital I/O lines to communicate with SPI or I2C slaves. I2C uses only two bi-directional lines, Serial Data Line (SDA) and Serial Clock (SCL), often pulled-up with resistors. 3V or +5V although systems with extra voltages are allowed.
