Hi, I use the attached code to realise a VU-Meter with 11 LEDs connected to a TLC59116 LED-driver. The TLC59116 is connected to the ARDUINO via i2c. I switched the i2c bus to 400kHz frquency (by replacing "#define TWI_FREQ 100000L" with "#define TWI_FREQ 400000L" in "twi.h"). The strange thing is…

i2c and A/D
