[SOLVED] Pinout for ICSP connector on Printrboard Rev F5?

[__Vinz__]

Good evening everybody,

I am in the process of installing the LED strip on my Play and this requires to update the firmware on my board (Rev F5). Unfortunately, the update does not work and it looks like the fuse locks are in place (based on what I read on the forum + what I see when using dfu-programmer). I am thus turning to use the ISP method to check that.

I have setup an Arduino w/ the ArduinoISP sketch to act as an ISP programmer and I can see it working when used on another Arduino (Adafruit Trinket) using avrdude.

Now, I have a very hard time to find the correct pinout of the ICSP header on the Printrboard. The reprap forum Printrboard page (https://reprap.org/wiki/Printrboard#Schematic) has the schematics but it is not obvious to me which pin is which. I have found posts on the forum showing others have this difficulty too.

Does someone know which pin is why on the ICSP header for the Printrboard (MISO, MOSI, SCK, V+, GND, Reset). A diagram like the following () from the Arduino page (https://www.arduino.cc/en/Tutorial/ArduinoISP) would really help.

Thanks much, this forum is a real gold mine for advanced topics such as this one and I am glad it stays alive now that Printrbot has closed.

This has the pin definitions for the PrintrBoard.

Thank you! With the page you point at, the schematics on it and this page (http://domoticx.com/mechanica-hardware-printrboard/), I was able to find the correct pinout and connect over ICSP using avrdude. I have opened a separate thread for the issues I am having once the connection is working.
