SPX-18018 Thing Plus C

Hello All,

I’'m trying to reuse and old SPX-18018 in a new project I’m starting.

In the old forums, there was a post that provided some changes to board.txt to reconfigure the pins so that the SD Card interface works.

Is there a way to access the old forum postings?

Thanks,
John

Yep - just click the magnifying glass @ top tight to search :slight_smile:

I think you are maybe after these 2?

@TS-Russell Thanks for the quick response but this does not give me what I need.

The SPX-18018 is a Spark X product and there needed to be a manual modification to the boards.txt to reconfigure the pins to make the SD Card interface to work.

I did search for SPX-18018 with no results.

Is there a way to access the OLD FORUM POSTS where the solution was posted?

John

Searching IS searching the old forum posts…they should all be migrated /accessible here

The sparkx version is almost identical to the red version…searching spx 18018 yielded nothing, meaning it was very likely the posts for the red version or maybe the github that you’re remembering? 2 of the 3 open issues there are SD related and have some notes within Issues · sparkfunX/SparkFun_ESP32_Thing_Plus_C · GitHub

@TS-Russell Thanks…I’ll dig into what you recommended.

Thanks…John

Hi @ChiefGeek63 ,

I remember seeing issues on the original SparkX Thing Plus C with some SD cards. Adding the 100K pull-up resistor to SD SDO (SPI POCI) solved those. I don’t remember having to change boards.txt or the variant pins_arduino.h, but it has been a while.

I hope this helps,
Paul

@PaulZC

Thanks for the info about the pull-up resistor. I think I remember something like this but it has been several years and my memory is not the greatest.
