I have recently bought Alexmos' 2 axis gimbal board and 3rd axis extension board, both boards are based on Atmega328/L6205. I am going to upgrade firmware. Your site (http://www.basecamelectronics.com/downloads) only provides firmware SimpleBGC_XXX.enc.hex. Is applicable for both boards? Otherwise, which firmware version should I use for 3rd axis extension board?
Mike, I flashed the main 2 axis board and extension board using the same firmware SimpleBGC_2_40b6.enc.hex. I set the 2 axis board up for roll and pitch, it works fine.
Now I am going to configure 3rd axis. I connected the USB/FTDI adapter to the 2 axis board and set Advanced/YAW to YAW ext.board. Is it sufficient to establish the master-slave link? Should I somehow configure the extension board as a slave? Or should I leave all its settings in the default state? Third axis behaves odd and I want to check my setup step-by-step.
