i2c nav gps - problem with Arduino Mini Pro + GY_80
Posted: Fri Jul 25, 2014 9:27 am
I have 2 MultiWii boards.
1. CRIUS MultiWii SE 2.0
2. Arduino Mini Pro + GY_80
and one I2C-NAV-GPS board.
When I connect I2C-NAV-GPS with [CRIUS MultiWii SE 2.0] Everything works.
When I connect I2C-NAV-GPS with [Arduino Mini Pro + GY_80] nothing works. Even GY_80 stop working and MultiWiiConf shows billions i2c erros. Even negative billions.
I do not add 2.2k pullup resistors to I2C. It seems GY_80 and CRUIS already have them.
Any ideas what may help to make I2C-NAV-GPS work with [Arduino Mini Pro + GY_80] ?
I use same wires without I2C-NAV-GPS.
