Hi Mario according to the OpenLog hook-up guide: baud - This command will open up a system menu allowing the user to enter a= baud rate. Any baud rate between 300bps and 1Mbps is supported. The baud r= ate selection is immediate, and the OpenLog requires a power cycle for the = settings to take effect. The baud rate is stored to EEPROM and is loaded ev= ery time OpenLog powers up. The default is 9600 8N1. < https://learn.sparkfun.com/tutorials/openlog-hookup-guide> If you are connecting through a FTDI =3D> USB then it is possible to use fa= ster baud rates than the usual by spoofing the actual rate in the driver - = FTDI have (had?) documentation on doing that. I have run FTDI devices up to= 3 Mbps by re-assigning the 300 baud setting (who uses 300 baud?) It is a w= hile since I did this so details are hazy but you need to modify the INF fi= le.

Subject: [OT] Similar to OpenLog but faster? Hello! do you know any product similar to OpenLog but faster? i.e. a UART to microSD FAT32 recorder, OpenLog would work but is limited to 115200 bps, I need at least 230400 bps for a projet and 921600 bps for anot= her. Even better, are there easy to use FAT32 libs for PIC32?
