Master board:
- J5: Power (GND, VDD),
- J12: I2S
- J13: I2C connected to Slave J13 I2C (SDA <-> SDA, SCL <-> SCL)
- JP2: I2C ADR => NO JUMPER
- J16: Volume Pot
- JP1: Forced Reset by uC, jumper on Pins 2-3 (up)
- J17 A3 wired to Slave J11 /Reset
uC Software: Master
Slave board:
- J5: Power (GND, VDD),
- J12: I2S
- J13: I2C connected to Master J13 I2C (SDA <-> SDA, SCL <-> SCL)
- JP2: I2C ADR => JUMPER ON
- JP1: Forced Reset by uC, jumper on Pins 2-3 (up)
- J11 /Reset wired to Master J17 A3 (control of Slave Amp Reset by master)
uC Software: Slave
Test sequence:
- Test master alone
- When master works, connect Slave as listed above
- On slave, set JP1: Forced Reset by uC, jumper on Pins 1-2 (down) to force the reset of the Slave
- Check that the slave TAS is successfully configured by the Master board, especiually that volume control works
- Check that the control of the slave Forced reset is working
- Once the Slave control by the master tests are OK, set JP1: Forced Reset by uC, jumper on Pins 2-3 (up)
