Daughter board Connectors The PTC04 main board has two connectors to the interface with the application. The PTC allows adding a full PCB in between (Daughter Board). This daughter board can be mounted on the two connectors. In some exceptional cases, a daughter board contains only a few wires from the Analogue connector to the application connector. The pins on of the connectors are described below.

Digital DB Connector (40 Pins) Mainly, the digital connector is meant to expand the programmer to extra needs. Address lines A0-A7 together with the Map Select Lines F8-FF allows to direct access an area of 2 K. Examples would be adding a simple addressed I/O register by using the selection lines. If more complexity is needed, a full FPGA can be mounted on the DB board Pins Names Description 1 – 8 A0 – A7 Address lines 9 – 16 D0 – D7 Data Lines active during Rd or Wr signals 17 Rd Read: A negative pulse will indicate a sampling of the data on the Data Bus 18 Wr Write: A Negative pulse will indicate when data is available on the Data Bus 20 Reset This signal goes low by powering the PTC or by pressing the reset button. This line can be pulled low by application. Check firmware documentation for resetting by software. 21-22 SCL / SDA I 2C Bus 23-30 F8,F9,…,FF CS lines when the address areas are accessed 31-38 Port E The full Port E of the ATmega core is mounted to these pins. This allows us to use advanced features like PWM, UARTS, Time Measurements, etc…. |
