I've been working on alternatives to updating firmware in the field, and wondered if a good alternative might be to embed a microSD card socket in a project, and use that to update firmware. It would require no cables or interface devices. Just copy the update file to the card, insert it into the slot, and power up the device, which would then detect the card, and use the file contents to flash new firmware, then (possibly) erase the file. I've downloaded the PFatFs.zip library from about 2016: https://forum.43oh.com/applications/core/interface/file/attachment.php?id=9251 Is t

Hello, I am using example code of energia Pfatfs library named "PFatFsfileTest". This program reads "T_READ.txt" file from sd card properly. But It can't write string "Hello world" 10 times to the file "T_WRITE.txt" into sd card. Instead, it just writes only "H". I am posting the original code of file below: /*----------------------------------------------------------------------*/ /* Petit FatFs sample project for generic uC (C)ChaN, 2010 */ /*----------------------------------------------------------------------*/ /* ported to Energia */ /* copy the two files t_read.t

Hello, I am working on a project in which we are using the MSP4305969 to measure temperatures and write data to an SD card. The datalogger is in a remote location, so the system needs to conserve enough power to log for a full year. In order to do this we are logging only every 15 minutes and powering everything down to a sleep mode between measurements. We use a transistor as a switch to take power away from the line of temperature sensors while the board is sleeping. That all works fine, my issue is with the SD card reader. We are using the "slot socket" for arduino https://www.amazo
