I have a DSO 201, but I can’t save thw waveforms in the SD card. Every time when I press the M key, appears the message “MICRO SD ERR.” How must I proceed to save the waveforms? The APP version that I’m using is 2.4 and the library version is 2.2.
Thanks.
It was recommend to use SD formater https://www.sdcard.org/downloads/formatter_3/ and make sure you format as FAT16 or FAT32.
Also you might want to upgrade to Benf firmware that has better SD support.
It could also be incompatible SD Card and you need another card.
