Hi,

STM32L432:

how can I trigger the Receiver timeout in the USART to detect if slave does not answer after transmission? Normally the timout function acts like described in the user manual.

In standard mode, the RTOF flag is set if, after the last received character, no new start bit is detected for more than the RTO value.

best regards

J. Baumann

    SO what are you doing which is  different to that, then?

    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.
