o. Getting two Velleman K8055N-2 boards to program each other “on the fly” via SK9 connectors
K8055N-2 board SK9 connector is a true wonder. It is also makes it possible to design a special cable for programing a PIC18F24J50 microcontroller on one K8055N-2 board from another K8055 board. The programming software is available from Downloads section. Program your PIC18F24J50 or PIC18F26J50 microcontroller with the latest firmware and PIC Programmer v2.9.9.zip or PIC Programmer v2.9.9 x64 .zip from Downloads section. If you prefere the original Velleman firmware, download PIC Programmer v2.0c application. Source codes are included!
Here is the programming cable blueprint:
- Turn K8055 or K8055N into a microcontroller programmer <-- an alternative way of turning your K8055N-2 board into a microcontroller programmer
To make the application work you need only to check the output signals and the input signals polarity. If the polarity of an input signal is wrong the condition in the appropriate "if" clause has to be changed by adding "not". If the polarity of an output signal is wrong, a logical "0" should be sent instead of a logical "1" and vice versa. You should only replace "set bit" commands with "clear bit" commands and vice versa, where needed.
