Devbugfix UART buffer cleaning: In the previous version a buffer cleaning function was used which resets the ringbuffer read index. As result the processing of data was stopped until the DMA write comes to the index 0. When reaching it the complete buffer was proceeded including possibly invalid data. The usage of the cleanbuffer function was replaced by the flush buffer function (meaning the data is discarded but the data index is maintained). There was already a function for this. Because the function was 99% the same as the read function, it was integrated into the ReadData function. Calling the function with parameter flush = 1 will result in a buffer flush. The workaround of the previous revision was updated to only be applied in case a DiveO2 sensor is operated in stand alone mode.

//  - the exact address is fixed in linker script CPU1-F429.ld,
//    so that every font can be used even when not included in the actual
//    binary (boot-loader, fonts, or firmware).
//
//  - Actual font data is defined by the OSTC4/FontPack project, that shall
//    be loaded before the firmware is executed.
//
//  - Font directory starts at address 0x081E0000. Each header is 12 bytes.
//    A 0xFFFFFFFF (32 bits) marks the directory's end.
//    It is stored between __font_directory and __font_directory_end;
//
//  - Font data (chars) is stored after 0x08132040 (end of font's SFirmareData).
//    So there is space for 0x081E0000 - 0x08132040 = ADFC0 = 694 KB of fonts.
//    Actual data is stored between __upper_font_data and __upper_font_data_end,
//    and uses 0x081b9a3a - 0x08132040 = 879FA = 542 KB.
