Updated: 2012-06-29 12:01:15
The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn’t exclusive to the Leonoardo, as [Michael] explains in a build he sent in – the lowly Arduino Uno can also serve as a [...]Downloading binaries using STM32 ST-Link Utility
Updated: 2012-06-25 21:34:26
Just a quick note to finalize STM32 flashing topic. As you may know ST also produces his own debugger/programmer called ST-Link. It supports either JTAG and SWD interfaces. You can purchase ST-Link USB adapter but there is a better option. … Continue reading →Flashing STM32 using J-Flash ARM
