.4 Debugging with VS Code
ESP-Prog programmer / debugger For details on installing see here. Installing debugger VS Code has a built-in debugger, its setup documentation is here. Apparently some people use it successfully for Espressif chips (launch.json “type”: “gdb”). Espressif have a dedicated VS Code extension for debugging which is likely the better choice (launch.json “type”: “espidf”) and that’s […]
Help and Community
ESP32 Forum – Seems really hard getting any actually support on this for anything tricky, we get nothing unless we email Espressif a link to our post that has sat there unanswered for days and ask if someone can respond to it. GitHub – We’ve found that raising issues with esp-idf on GitHub gets a […]
UART Pins
UART0 The ESP32 can be programmed via its UART pins. However it doesn’t have to be if you want to use them for something else. It is also possible to program it using the JTAG interface pins. Pin assignment (other than UART0) UART signals can be connected via IOMUX for specific GPIO or otherwise the […]
