FTDI Chip develops innovative silicon solutions that enhance interaction with today’s technology. When a designer needs to add a USB port, rest assured that FTDI Chip has a full range of USB solutions to get the job done. Official reference can be found here.


You can configure debugging tool using debug_tool option in “platformio.ini” (Project Configuration File):

platform = ...
board = ...
debug_tool = ftdi

If you would like to use this tool for firmware uploading, please change upload protocol:

platform = ...
board = ...
debug_tool = ftdi
upload_protocol = ftdi

More options:


Windows:See https://community.platformio.org/t/esp32-pio-unified-debugger/4541/20
Mac:macOS contains default FTDIUSBSerialDriver driver which conflicts with debug tools which are based on this chip. FTDI Chip company recommends removing this default driver from a system. Everything should work after system rebooting. See detailed instruction in official application note (Page 16, Section 4: Uninstalling FTDI Drivers on OS X) AN134: FTDI Drivers Installation guide for MAC OS X
Linux:Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.

ESP-IDF Espressif IoT Development Framework. Official development framework for ESP32.
Freedom E SDK Open Source Software for Developing on the SiFive Freedom E Platform
mbed The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
PULP OS PULP is a silicon-proven Parallel Ultra Low Power platform targeting high energy efficiencies. The platform is organized in clusters of RISC-V cores that share a tightly-coupled data memory.
Simba Simba is an RTOS and build framework. It aims to make embedded programming easy and portable.
Tizen RT Tizen RT is a lightweight RTOS-based platform to support low-end IoT devices
