7.5 Programming

Programming the FPC202 is accomplished through a single SPI or I2C interface, depending on the PROTOCOL_SEL pin state. To simplify configuration, a C function library is provided which can be integrated into the system software or used as a reference. The existence of basic SPI or I2C read and write functions is assumed within the provided C function library. The exact implementation of SPI or I2C read and write functions is beyond the scope of the C function library. Request access to the FPC202 Programmer's Guide (SNLU229) here for the register map and more details.
