Post by thread:[PIC]: The Kitsrus K150 og Quasar 3150 programmer:

I have built the 3150 USB-programmer from Quasar Electronics, which I think is the same product as the K150 programmer from Kisrus. I want to use it in the ICSP mode. I am not quite certain on how to use the pins. The programmer has 6 pins while ICSP-programming in the Microchip documentation is done with 5 pins. The programmer has a "LOW" pin, and I can't find such pin in the Microchip documentation. Unfortunately there is no documentation on the pins of the programmer and Quasar could not give me any documentation on the pins. Does anyone know what this "LOW"-pin is?

I haven't heard of/seen the 3150, so I can't comment for sure. However, my guess is that the "LOW" pin would be to pull the low voltage programming pin on the PIC low during program. Hope this helps.

part 1 2571 bytes content-type:text/plain; charset="us-ascii"; format=flowedBelow is a short write-up I created for someone else about using the K150 with a "normal" ICSP. I haven't looked it up right now but I believe that the blue wire is for low-voltage programming with some PICs. I didn't need that for the PICs I was using so I didn't use it. You can deduce all of this by looking at schematic enclosed with the kit and then what pins are connected to where on the ZIF socket. i.e. find MCLR on the ZIF, and then see which pin that is on the 6-pin connector that the K150 uses, etc. Dan <----- snip ------> -------------------------------------------------------- A short stub of a cable is included, but I recommend creating a new longer cable using ribbon cable. Any cable that has 5 conductors of 22AWG to 30AWG wire will do. Attached is a picture showing how the short cable included with the programmer can be wired up. Note that the blue wire is not used and should be taped up or removed. The pin-to-pin version is as such. 5 pin connector 6 pin connector Pin 1 Pin 1 Pin 2 Pin 5 Pin 3 Pin 6 Pin 4 Pin 3 Pin 5 Pin 4 Pin 2 - unconnected DigiKey WM2004-ND (Molex 22-01-3067) (6 pin connector) WM2003-ND (Molex 22-01-3057) (5 pin connector) WM2312-ND (Molex 08-55-0102) (pins) At 01:28 AM 12/7/2003 +0100, you wrote: {Quote hidden}>I have built the 3150 USB-programmer from Quasar Electronics, which I >think is the same product as the K150 programmer from Kisrus.

The LOW pin is simply an open collector output. It can be used to pull "something" low while programming. This may the the LVP pin, the OSC1 pin or something in your hardware. regards Tony Lis og Søren wrote: {Quote hidden}>I have built the 3150 USB-programmer from Quasar Electronics, which I >think is the same product as the K150 programmer from Kisrus.
