I finally have my IMU up and running and outputting all the data I could ever possible want at 50Hz. The next step for me is the autopilot side of things. Currently the IMU outputs its data over standard UART. This means that my other micro (Arduino nano) must have at least 1 UART which it does. The problem is that I require long distance two way communication and I also want to design around a Spektrum satellite receiver which also communicates over a serial interface. This means that I need to find an extra 2 UARTS somewhere.
- I have been looking at using either the Mbed micro (M3 Cortex core)
----Dont like the online compiler idea
----Do like the easy drag and drop programming
----Do like the support and community
----LOVE the form factor (45 x 25 mm)
----More expensive at around $80
- I have been looking at Xduino which is also M3Cortex (cant seem to get in touch with the guy there)
----Seems to be a lack of support
----Costs only 24USD
-Was hoping to find an I2C chip which would give me access to extra UART ports....Cant find one :(
I just wanted to know if you guys had any thoughts or alternatives to those I have proposed. I realize that the new ardupilot is coming out and will fix this problem but I am keen on using my own hardware.
