Arduino Raspberry Pi Interface with LCD Display
For an explanation on the operation of the LCD part of this page see Connect a Serial LCD Display to Raspberry Pi
For an explanation of how to read 16-bit code from Arduino without the use of I2C see Serial Read from Arduino to Raspberry Pi
The Arduino sketch is arduino_ds18b20X2.ino.
This program is a combination of the above two programs. Arduino operates any number of sensors while Raspberry Pi reads the integer results, does any conversions, and displays the result on a serial LCD display.
The program will reset Arduino and the sensor routines/calls are in the Arduino setup section. The return value is stored in a variable and read back by Raspberry Pi.
Arduino is programmed to operate as a 16-bit TLC548 ADC.
The Python code is rpi_arduino3.txt.
The GPIO connections are as follows:
CS = 18
dataBit = 24
Reset = 25
