Posted on March 22, 2016 at 16:58Rev 3 of the User Manual shows Pin 9 of CN14 to be PB7 (USART RX) in both Figure 3 and the schematic (Page77); in Table 33 it shows CN14.9 as PC3. Where does PB7 come out to a header if at all? My USART_RX signal on...
Posted on August 28, 2017 at 18:59Found it....I was using the DAC sample and hold which uses the LSI clock (as does IWDG). Disable the sample and hold and all is fine. Enabling IWDG affects the output of the sample and hold in some subtle way behi...
