Hi, I’ve purchased two SDloggers from SeeedStudio, and one of them seems to have wrong firmware written; it outputs “Type any character to start” via UART when power up, and starts interval logging something (ADC value?) in CSV format to SD card. (Another one outputs initializizing status, “12<” when power up.)
I wish to write correct firmware to this SDlogger, and seeked how to build it. Descriptions on SDlogger says that it has a OpenLog firmware of v1.6 compiled with SDHC/FAT32 and larger bufffer options. I obtained OpenLog v1.6 source, but I can’t find where to edit to set SDHC/FAT32 options; they are supported in a v2 firmware…?
Where to edit original OpenLog v1.6 firmware for SDlogger?
