8mz arduino @ 3.3v with AF SD Card Library? Moderators: adafruit_support_bill, adafruit

[turkey]

Does anyone know if I can use the adafruit SD Card library AF_SDLog library (used for the gps logging shield) with an arduino running at 8mz?

I've got an atmega328 running at 8mz, but with the regular bootloader, so it's effectively running at half speed. (19200 baud serial actually runs at 9600, as I understand)

The FAQ about the library that the adafruit library was based on (by Roland Riegel) says that I can adjust the MCU clock speed in the makefile, but the adafruit library does not have a makefile since it's been built.

So, can I use the AF SD Card library at 8mz with or without adjustment, and with what adjustment?

Thanks all!
