I just tried to compile this example code, but IDE complains about undefined reference to `myFont'
This is not in the sketch itself, but in data.c (which seems to hold a bitmap for the font and some logo).
I have no idea how this works, using the font.
The error is reported in line 144 of the sketch, which says:
void SendChar(unsigned char data)
Wire.beginTransmission(OLED_address); // begin transmitting
Wire.endTransmission(); // stop transmitting
There is only 1 line that is not comment (it sarts with "i2c"), and that's line 144 which is referred to by the error form IDE.
If i understand correct, this is supposed to send data to the display but i really don't know.
Can anybody tell me what this means and how to solve this ?
I've got the same display (twice) and didn't get it to work yet.
Twice because the shop sent me another one as the first one wasn't working.
But both aren't working.
I've used a I2c scanner to find the display but even that doesn't work, but i would like to try everything possible to get it to work.
