Arduino Library Limitations
Reminder, the SparkFun FPC2534 Arduino Library currently only supports ESP32 and Raspberry RP2 (RP2040, RP2350) boards when using I2C. The I2C Implemention of the FPC2534 device performs a dynamic payload transmission that is not supported by the Arduino Wire library. Because of this, a custom implementation is provided by this library for the ESP32 and RP2 platforms. If you'd like to create your own custom implementation for a different processor, you can take a look at I2C helpers we made for the ESP32 and RP2 processors here.
