STM32CubeMX configuration bug report

Posted on March 18, 2015 at 07:28

I use the STM32CubeMX.

However, it has a wrong configuration problem for UART.

I want to use the asynchronous RX only mode, but it's not configurable.

My configuration procesures:

1. Configuration -> Peripherals -> UART4 as Asynchronous

Then 2 pin is set as UART4_TX, UART4_RX

2. I want to use the RX only, so I disable the TX pin.

Then the UART4 configuration is changed as Disable.

As a result, I can't configure as Asynchronous RX only mode.

You have to select single wire (Half-Duplex) mode, then the TX pin can be used for both reception and transmission.

RX pin will be free.
