Need periodically (MCUxpresso, SDK only) read out values from sensors and store to flash incuding time stamp.
RTC library - trying to use sensors/pcf2123.h from SDK, but seems missing functions around SPI, which are required for callback:
uint8_t (*SPI_Read)(uint8_t *writeBuf, uint8_t *readBuf, uint32_t readSize); /*!< External SPI read function */
uint8_t (*SPI_Write)(uint8_t *writeBuf, uint32_t writeSize); /*!< External SPI read function */
Could you please point out SDK functionality here ?
