Using SPI with the Backpack?
il y a 6 ans
Hi, what pins does the Backpack use for SPI? The standard pins for Uno are 10/11/12/13 but I'm trying to use this shield:

and running into problems. I realize that the META is really a Zero vs. Uno, correct - which suggests the ICSP header would be required, but...there isn't one? :)

would be better when you use the ESP8266 or ESP32. Its cheaper and can connect via Uart.
And also easier to get and more support in forums.

It's a zero so the SPI is not through the pins 10/11/12/13 but the ICSP header... which couldn't fit on the Gamebuino Backpack. You can still access them through the labelled pins though :-/
PS: Agreed that the ESP8266 would be nice, you could even use it as a co-processor :P

@AurélienRodot just wondering if you're able to confirm so that I can proceed with my project:
Oh! Let me know if I'm misunderstanding: I see MISO/MOSI/SCK on the PCB between Analog and Power - are you saying to just directly connect those pins to the ICSP block on the shield?
:)

I do have ESP8266s and 32s that I can try, but this is the only wireless "shield" I have so wanted to start here first...since I thought it would be "easiest"! :)
