I have a Dualsky XM7010GB-SR attached to a simplebgc tiny rev A with a power supply suppling about 13 V of power to the battery in connections. I keep getting Sub-Code 29 error, and in debug I am getting the following:
WARNING: STACK CRITICALLY LOW!
I2C errors: 9218; by device: 0x2=541; 0x20=11010; 0x1=543; 0xde=7425;
