Matrix board UserManual
|Like all the other boards, the matrix is a double sided printed circuit board. This means that the layout is both on the top and the bottom side of the pcb. Start soldering the 'lower' parts (like the diode's) and slowly tke the higher components. The AD75019 chip is mounted into a socket. Be aware of the pin 1 connection of the socket.

Matrix board connections
When all the components are mounted on the board, it's time to connect the board to a driver or microcontroller. For driving the Matrix, you need to know how you can exchange serial data from one device to another. Checkout the datasheet of the AD75019 to get a better understading of how this chip works.
The board has three voltage regulators, creating -12V, +12V and +5V. For the regulators to make the right value, the board should be connected with at least +14,5V and -14,5V (the voltage regulators do need at least 2,5V to regulate). If you apply the matrix board in an already existing circuit, with regualted power available, you do not have to install or use the voltage regulators. Be sure not to exceed the (+/-12V).
|To be able to address all switches seperately, you have to send 512 bits. OSC communicates with 32 bit wide databytes. This means that you have to send 16 OSC values.
