I have a strange device I want to talk to - it's a vintage keyboard. It seem to talk UART, but the bit string is unusually long - 21 bits. UART component supports only 8. I can bit-bang it - but would be grateful if you advise me how to program UDB for this task.

Hi,

In PSoC Creator Code examples please refer the UART custom component implementation to understand and implement your custom UART component.

To understand the implementation and how to configure UDBs you can refer the following application notes:

Either you can use the above documents and implement custom component or you can multiplex 3 different existing UART components sending the data one after the other on the multiplexed line in the firmware.

Thanks

Ganesh
