Hi, im working with my newest project. I use digispark board (attiny85) to make a compass ring led with HMC5883L mag sensor. But there is always a problem when i want to upload the program. Any of you ever working with the same board and sensor? I need help in quick way, so if you can help me, just send me on message!! thank you
Do not cross-post. Other thread removed
Post a wiring diagram of your complete setup. If you don't use the chip directly, post also a link to the schematics of your breakout board.
If you only used the I2C signal it should work, if you connected the IRQ signal you might interfere with the Digispark USB interface.
