   - finally you can use the SWD pins on the programming connector to [[stm32f1xx#swj|flash using SWD]], provided you have and SWD adapter. This also allows to properly debug the firmware. :!: For some unknown reason sometimes after power-up the SWD adapter will not be able to find the micro-controller. Briefly reset the micro-controller by shorting RST to ground using tweezers (follow the RST indication on the board). From there on it will always be detected.   - finally you can use the SWD pins on the programming connector to [[stm32f1xx#swj|flash using SWD]], provided you have and SWD adapter.

 The closest alternative to the BusVoodoo is probably the [[http://dangerousprototypes.com/docs/Bus_Pirate|Bus Pirate]], and this is actually the device I used for a long time before I decided to make my own because the shortcomings piled up. The closest alternative to the BusVoodoo is probably the [[http://dangerousprototypes.com/docs/Bus_Pirate|Bus Pirate]], and this is actually the device I used for a long time before I decided to make my own because the shortcomings piled up.
