Hi!

I use a CY8C6347BZI-BLD54 together with PSoC Creator 4.2.

I try to connect the output from a comparator to the input of an UART SCB-block, but when I try to build the project the routing fails.

Is it not possible to do this kind of connection?

Hi Kalle,

If you see the component datasheet,
"By default, the UART pins are buried inside Component: UART_1_rx, UART_1_tx, UART_1_tx_en, UART_1_cts, UART_1_rts and UART_1_tx_rx. These pins are buried because they use dedicated connections and are not routable as general purpose signals"

So you will not be able to connect the comparator output as dedicated connections are already available for it. You may have to use an additional pin to route the output of the comparator to the UART input externally.

Best Regards,
Vasanth
