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 July 24, 2013 at 17:50Hello, I'd like to prototype a board with a STM32F205RGY MCU ... this is the WLCSP package of the F205RG. Seems I can't find it on any distributor site ... Thomas.
Posted on February 13, 2017 at 10:44 I simply use the normal Functions given by RTC-Lib from Cube, means I use these Calls: uint32_t tFormat = RTC_FORMAT_BIN; ... HAL_RTC_SetDate(&hrtc, &myDate, tFormat); HAL_RTC_SetTime(&hrtc, &myTime, tForma...
