The program runs fine on an 18m2 but when I down load it to an 20m2 it doesn't run. It's a simple clock program and I've made sure the SCL and SDA are on the
proper pins of the 20m2. There are no other connections to the 20m2, just the SCL and SDA. I've Tried different setfreq, but that has no effect. There is a 1307 clock chip
and a 128 x 64 oled on the i2c bus. The display stays blank after a download. The bread board wiring is the same, the only change is the 20m2.
