Hi, I'm interested in your project. I'm a full C developer for embebed systems mainly using the Microchip line. I have lot of experience working with external and internal memories (Flash, EEPROM), different protocols (RS-232, I2C, etc), Analog inputs, Digital to Analog outputs, interrupts, sensors, standard LCD and graphic LCDs, RTC, IoT, etc.
I would like to hearing from you more details on the project so I can provide a better bid amount.
Thank you!
