VGA
The Arcade shield outputs VGA signals via the VGA connector. The pin out of the
VGA connector is detailed in Table 4
The arcade shield does not support DDC.
Audio
The audio circuit is not populated on the standard Arcade Shield. It may be
populated on a later version.
Audio signals are generated using high speed PWM signals from the XMOS L1
processor. The PWM is filtered and amplified. The audio amplifier can drive 4 or 8
Ohm speakers.
The audio amplifier can be controlled and read using I2C. The I2C signals (SCL, SDA
are taken to pins A4 and A5 of the Analog connector. The external processor board
can configure various parameters of the amplifier including:
For more information on the I2C protocol, refer to the TPA2016 data sheet from Texas
Instruments.
