A lot to wade through there, would be a bit more efficient with a switch/case for the decode. Even an if/then/else construct.
The problem, I suspect, is that you are sending ASCII characters, '0' to '9' and expecting them to be decimal numbers 0 - 9, but are instead 0x30 .. 0x39. You need to translate them, either manually or with atoi(), and you perhaps want your 7-Segment decoder to have a default for characters it doesn't recognize, like '-'

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
This user trying to make UART data to 4 digit display.In case of SPI data, if uint8_t pDataRx[4] is turned to BCD and fed them in 74HC4511 decoder-driver to 4 digit display. It will work? Further translation is needed or not?
