ARDUINO serial monitor working with 31250 baud for easy debuging while writing MIDI scetchs. I'm using a siliconLabs CP2102 USB to TTL bridge. Normaly this device can not solve the MIDI baud rate, but there is an easy to use configuration tool @ the silicon labs page, called 'Simplicity Studio'. Istall it and you can change the baud rate from 38400 to 31250. It's just a click and it's done. When ever you like to have a MIDI MONITOR within ARDUINO, just set the ARDUINO serial monitor to 38400. It's that easy.
