Posted on January 27, 2016 at 14:49Hi@allis it possible to get the usual ''printf'' outputs on the SWO pin without any Debugger(like ST-link) conected?My goal is to connect a plain FTDI Uart2USB converter to the SWO pin. And just read the outputs.If...

Posted on August 17, 2014 at 15:34 Hello,I'm currently quiet frustratedI'm trying to set up with the RTC wakeUp register an interrupt of 128Hz. For the RTC the LSI is used (I know not very precisely but for current testing propuse its enough)here i...

Posted on January 28, 2016 at 15:29it's a communication device where all UARTs and SPIs are used.a simple UART was used before, but moving to a cheaper MCU were containing to have less UARTs available :)so no alternativ.

Posted on January 28, 2016 at 12:03>Why can't you have STLink connected, and simply snoop on the SWO pin with the FTDI/any other 3V USART Rx?thanks for the feedback.Well I can and it looks like this have to be than the final solution.Would just be g...

Posted on January 28, 2016 at 09:19its NRZ coded with start and stop bitsand I get the correct data out of a connected UART with 2MBaudso its pretty close to an UART :)the only problem is to get this outputs while there is no debugger connected.
