ESP32

[rafaeltgross]

I'm trying to program my ESP32-WROOM but, unfortunately, is not working.
Here is my board
https://forum.fritzing.org/t/esp32s-hil ... plate/5357

The pins does not match the ones on FC9.

Can anyone please help me?
Thanks
Rafael

Hi Rafael,
Even if the pin mapping on the board is different,
you should still be able to select IO via the GPIO/pin numbers,
e.g. GPIO6 is PORTA6

Hi LeighM,

Thanks for your reply, I will try.
When is PortB. Where I can find a better description about these Ports?

[LeighM]

Each PORT represents 32 pins.
So PORTA 0 to 31 is GPIO0 to GPIO31
PORTB 0 is GPIO32 etc...

So here is my test report
the right side is working GIOP23 to GIOP15 (so from pin 23 to 37)
the left side GIOP13 to GIOP32 (from pin 7 to 15)

before I was testing all the non working pins such as GIOP-6, 7, 8, 9, 10, 11, 34, 35, 36, 39.
So is there any reason why these ports are not working?

Can I use UART0 ,1 and 2 in this board with FC9?

many thanks
Rafael

[LeighM]

UART0 is best avoided as this is the debug channel.
Do you have another unit to test?

Hi, Rafael
I believe IO34 to IO39 are inputs only.
That can easily catch people out.

Thanks for the reminder Martin
