ESP32 1Mb/s UART Interrupt Driven Buffer
Budget: $15 – $25 USD
This project is for interrupt driven UART firmware on an ESP32 that can receive a 5KB file over UART at 1Mb/s and place into RAM buffer. Serial.available in the main loop is not fast enough to achieve this performance. Freelancer must have ESP32 and another MCU to transmit test file.
