STK1002/Used STK1000 interfaces

From AVRFreaks Wiki

Jump to: navigation, search

STK1002 and the AP7000 utilize all hardware features on STK1000. The Timer C interface routed to the PCI style expansion connector is not connected since AP7000 only have two Timers.

Interfaces

Refer the interfaces section of the STK1000 help files to learn how the interfaces are used on STK1000.

* Jumper settings to activate interface

(1) Note that DMARQ0 and DMARQ1 pins share functionality with interrupt pins and they are therefore connected to debouncing capacitors on the interrupt switches. If these DMA request lines must be used on the PCI connector then those debouncing capacitors must be removed from STK1000. It is therefore recommended to use DMARQ2 and DMARQ3 for PCI style expansion boards.

Miscellaneous signals

  • The internal DAC on AP7000 is connected to the internal DAC lines of STK1000.
  • The RTC_WDTEXT signal from STK1000 are not used in any way on STK1002.
