It is not compatible with the following boards:
- Lemon-IoT-BLE-nRF52832 - The nRF52832 reset pin (P0.21) shares the same I/O line as MOSI. While the reset line can be reassigned, the hardware has a 0.1uF capacitor that effects signal integrity.
The following examples are available:
- uSDCard - Provides basic source-code for mounting a filesystem, writing and reading to a file.
