![]() ![]() ![]() This is a pinout of the connection to the satellite (red connector in the picture above from Dells support page):Īfter studying the datasheet for TDA7433 and this page about I2C I wrote a controller program for a Atmel Mega8 using avr- libc and connected it to SDA and SCL together with 4.7 kOhm pull-ups (there are no pull-ups on the circuit board inside the ACS295). The speakers are controlled by a TDA7433 audio processor that speaks I2C with the controls on the satellite.
