   Since I last looked it seems they have added a new feature, the st-link server. It appears to offer access to both the debug interface along with the Serial Wire Viewer (SWV) monitoring port. https://my.st.com/content/my_st_com/en/ … erver.html You might want …

   …g to get a specific type of sound, but you could try adding an RC network between the STM32 and the transistor to form a low pass filter e.g. set to 10kHz or perhaps 5kHz, as that would give things a more pleasing sound.

   …l converter and as a debugger also. In the past, I used the ST-link for programing my stm32 boards. During the projects development I saw that I had to develop upto 4 simultaneusly projects. I forced to disconnect my st-link from the one stm board to the other…

8. very small STM32F405 board

   …s1117 has a 1v dropout which would be ok for 5v but with 4.2v that leaves 3.2v at the stm32 even when fully charged but i’d guess f4 being more power hungry vs f103, i’m not sure if we could or if it make sense to swap the on board LDO for a ams1117 or lm1117 …

9. what if we make a custom programmer for STM32 using an AVR arduino?

   I guess its for people who have a STM32 board but forgot to get a USB to serial and can’t easily / quickly get hold of one.
