    I recently created and completed a project to replace the processor on a PCB with an alternate. This project is complete, and I have prototype PCBs ready to receive code. But the Freelancer that completed the PCB project isn't familiar with the ATMEGA4809 processor and couldn't help me upload the Arduino IDE native code onto the new PCB. I need someone to review the schematic and walk me through exactly what to do to upload my code to the new PCB, including what hardware to buy if what I have (Sparkfun AVR Pocket Programmer) doesn't work. Ability to communicate clearly in English is required.

    The objective of this project is to modify existing firmware to interface sht30 sensor with PIC microcontroller. The existing firmware was written for HDC1080 Humidity sensor and works fine. However HDC1080 sensor was replaced with sht30 and now a firmware update is required to get values from sht30. Code is written in MPLAB and is fairly documented. The major portion of the code deals with menus on LCD, which works fine so only changes will be required are "to read humidity values from sht30". Ideal candidate will have prior experience with sht30 sensors and PIC microcontroller programming using MPLAB. Please start your response with the default I2C address of sht30 and we will know you are interested.

We need to write a custom firmware with additional function that MC SDK doesn’t have as standard - holding a motor in one position. When any rotational force is applied, the motor should try to stay at the same position, when its power is not enough rotate as slow as it can.
