Otherwise you can refer this also : https://www.adafruit.com/datasheets/an97055.pdf

I would like to use 5V on all circuits and supplies.

Is it possible to use 5V on the I2C pins of RPI?

I cannot see that a levelshifter will work, please help.

Thx

Check the following.

  1. Ground of both Raspberry Pi and PIC should be made common.
  2. Baud rate, Parity Bits, Number of bits should be same
  3. Raspberry Pi output is 3.3V while PIC is 5V (3.3V PIC is also available). So you should use level shifting to prevent any possible damages to Raspberry Pi.

1.  Using UART of PIC Microcontroller – MPLAB XC8 at https://electrosome.com/uart-pic-microcontroller-mplab-xc8/

2. Using UART on raspberry Python. Link at https://electrosome.com/uart-raspberry-pi-python/

The project i am working on will have me send pure strings(texts) from raspberry Pi to PIC and vice versa using UART, I have wired the circuit as expected but the message i am getting on the raspberry Pi and on the PIC is sort of garbled. I do not know what is responsible for this, please does anyone have an idea of what i should do to get the messages in the write format. Thanks!

Did you write the program for reading sensor data in python?

SD card is chosen because of its advantages. Up to 512GB SD cards are available in the market.
