Help writing a component to read UART data

You can probably do this without a component if you want.

[How to] UART read without custom component

The UART Bus component provides a write action but no read actions. Typically the UART read is implemented in a custom component that also does the processing. The UART debug sequence can be exploited to act like a call back function whenever there is received data to process. So basically instead of creating a small custom component a large lambda call can be used in the UART debug yaml. This is shared to hopefully help make implementing UART devices a bit easier for average users. It seems t…

[How to] UART read without custom component

Just providing this little example. uart: id: uart_bus tx_pin: GPIO21 rx_pin: GPIO20 baud_rate: 9600 debug: direction: BOTH dummy_receiver: true after: # bytes: 9 # timeout: 10ms delimiter: [0x7E] #Specific end byte sequence: - lambda: |- UARTDebug::log_int(direction, bytes, ','); // Log the message as int. UARTDebug::log_hex(direction, bytes, ','); // Log the message in hex. …

device-name - can this be gotten from somewhere?

There is a way which I can’t seem to find right now. But substitutions might do the job.

Edit: have a read of this thread.
