IO Extension Board Recommendation for DevKitC

Postby tugrulguclu » Mon Dec 02, 2019 3:40 pm

Hi
I recently started to use ESP32 DEVKit-C (https://www.ebay.co.uk/itm/282413957033)

I was wondering if there are any ready to use boards so I can connect to DEVKit-C and R/W to some I/O points using some LEDs and buttons.

Also Could you let me know if it is possible to use Ecipse and gdb to debug my programs running on the DevKit-C. As far as I understand

DevKit-C does not have Jtag support which makes debugging impossible

It doesn't have a dedicated JTAG port, but the JTAG signals are still available on GPIOs. As long as your program doesn't reconfigure those GPIOs, you can hook up your J-link to that.

I have the same or very similar 38 pin board and I use the Olimax Tiny-H JTAG debugger on it.

There is a pin out here

Then a video on setting up debugging with Eclipse CDT here, skip to half way

You need TMS, TDI, TCK, TDO and GND so you will need to find those on your JTAG debugger pin out and connect them to the ESP32 board pins as shown on the pin out above.
