SPX-18018 Thing Plus C

[ChiefGeek63]

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

I think you are maybe after these 2?

SPARKFUN ESP32 VROOM PLUS C does not see SD card when using ARDUIN IOT CLOU EDITOR

SPARKFUN ESP32VROOM PLUS C(PART# WRL-20168) does not recognize the SD card when using the ARDUINO IOT cloud editor. The sparkfun example code SD_test.ino works fine. Here is the Arduino IOT code I am using, I am getting "Card Mount Failed"and “No SD card attached”; /* Sketch generated by the Arduino IoT Cloud Thing "Untitled" https://create.arduino.cc/cloud/things/6b7debab-1df0-4ab0-b3a8-96d9381a8a44 Arduino IoT Cloud Variables description The following variables are automatically generated and updated when changes are made to the Thing int TargetLaunch; Variables which are marked as READ/WRITE in the Cloud Thing will also have functions which are called when their values are changed from the Dashboard.

ESP32, SD_Test.ino writing to SD

I am programming SPARTKFUN VROOM Thing Plus C for use with the SD card and I am struggling with how to write a int to the SD card. The sample code works fine with characters or text, i.e “Hello” but the FS.h code uses pointers which are not my strong point. The SD_Test code uses appendFile(SD, “/LOW_2”, “World!\n”); to send text (“World!”) but how would I sens a integer ; replacing World! with my integer(count) does not work. I am incrementing the integer count and I want to write it to the SD card but I am stuck. Following is my complete code /************* 4/20/2023- STARTED WITH SPARKFUN WIFI EAMPLE CODE"SPARKFUN_WIFI.ino" ADDED SD_Test.ino, removed un-needed code and added counter code without RTC ***********/ #include <WiFi.h> // WiFi network name and password: const char * networkName = "xxxxxxx"; const char * networkPswd = "yyyyyyyyyy"; #include "FS.h" #include "SD.h" #include "SPI.h" const int sd_cs = 5; //Thing Plus C int targetPin = 33; //INCREMENT TARGETS COUNT, SE…

@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?

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.
