Hi there
I try to read/write to a SD card with a CubeCell GPS v1.1 (HTCC-AB02S).
So far with no sucess.
I’m using the SD library of Sparkfun (this one https://github.com/arduino-libraries/SD).
With the exampla CardInfo (this one https://github.com/arduino-libraries/SD/tree/master/examples/CardInfo) the output in the serial Monitor is “inconsistent”… Sometimes the code is reading right, sometimes there is just rubbish, sometimes there is no card at all… just from one reset to another…
something like:
��F�
Initializing SD card…Wiring is correct and a card is present.
Card type: SDHC
Could not find FAT16/FAT32 partition.
Make sure you’ve formatted the card
Initializing SD card…Wiring is correct and a card is present.
Volume type is: FAT32
Volume size (Kb): 30251008
Volume size (Mb): 29542
Volume size (Gb): 28.85
Files found on the card (name, date and size in bytes):
SYSTEM~1/ 2022-11-02 10:24:50
Also with the Datalogger example: sometimes it works, creates a file on the SD card with entrys, sometimes the output is just “Error opening Datalog.txt” sometimes it gets stuck (no serial output at all) sometimes just the first entry (0,0,0 because the ADC dosn’t read nothing at all) ant then “Error opening datalog.txt”
Acording to this post Read/write to SD card there was/is a solution…i tried it with 3 different cubecells an 2 different sdcard reader. it’s alway’s the same.
cardreader is this one https://learn.adafruit.com/adafruit-micro-sd-breakout-board-card-tutorial/arduino-wiring
the next question i have, what do i have to modify to get i work over SPI1 (so SPI0 is always free for LORA) but first get a stable reliable reading…
What im missing??
