Wiring Versions

As of January 2010, there are 3 recognized wirings, named DASA, DASA2, and DASA3. None of the DASA cable configurations provide power to the microcontroller, so power must be provided externally.

DASA

When using [uisp|UISP] or [avrdude], specify this cable with the flag " -dprog dasa ". This is the configuration used for most Fab Lab serial programming cables.

  • microcontroller RESET <--> serial port RTS
  • microcontroller SCK <--> serial port DTR
  • microcontroller MOSI <--> serial port TXD
  • microcontroller MISO <--> serial port CTS
  • microcontroller GND <--> serial port GND

DASA2

When using [uisp|UISP] or [avrdude], specify this cable with the flag " -dprog dasa2 "

  • microcontroller RESET <--> serial port !TXD (the ! means that the signal must be inverted)
  • microcontroller SCK <--> serial port RTS
  • microcontroller MOSI <--> serial port DTR
  • microcontroller MISO <--> serial port CTS
  • microcontroller GND <--> serial port GND

DASA3

When using [uisp|UISP] or [avrdude], specify this cable with the flag " -dprog dasa3 "

  • microcontroller RESET <--> serial port !DTR (the ! means that the signal must be inverted)
  • microcontroller SCK <--> serial port RTS
  • microcontroller MOSI <--> serial port TXD
  • microcontroller MISO <--> serial port CTS
  • microcontroller GND <--> serial port GND
