This allows devices to be copied easily. The target memory or microcontroller can be either powered by PRESTO Programmer 5 V nominally or can be powered by the target, within a voltage range 2.

GO button allows user to start programming easily, without the need for a PC keyboard or mouse. Overcurrent limitation of target supply and programming voltages remarkably reduce the risk of damaging the target device because of user mistakes. Target supply overvoltage detection is also implemented.

Software upgrades are freely available for all users on the Internet. They contain new device support, new functions and algorithm updates when required. This is important as our Arduino based programmer needs to be able to fool MicroPro into thinking a real programmer is connected. In any case, I found that the protocol spec had a few small deviations, but was mostly accurate.

The next step was to create a sketch that fools MicroPro into thinking there is a programmer connected. Later on, this would be fleshed out with various functions that actually interact with a connected PIC. One thing that is very different about programming PICs is that they need a programming voltage of around 13V applied to one of their pins to correctly enter programming mode, so I needed a way of generating and switching a 13V supply with an Arduino.

Because there is very little current needed at the programming voltage, I settled on using a voltage tripler circuit called a charge pump based on capacitors and diodes, and then switching the 13V with an opto-isolator. The other pins use normal 5V digital logic, so were simply connected to the Arduino pins via resistors.

The voltage tripler needs a continuous stream of two out-of phase square waves to drive it, and I was able to generate this by using the PWM output on pins 9 and 10 on the Uno, with a little tweak to the code to create an out-of-phase signal instead of the normal in-phase signal that would be created. This is why this project may not work on other Arduinos, as the hardware timer is specifically attached to these two pins, but only on the UNO.

This sort of circuit can be extended to more stages to create an even higher voltage, but with a decreasing current capacity. The tripler circuit makes up the left half of the circuit up to the third capacitor. In an ideal scenario, the first capacitor is charged up to 5V via the first diode when D9 is low, then when D9 goes high, the first capacitor is lifted to 10V at its positive end, and so forth down the line, with each stage adding 5V.

Extra stages can be added using two waveform pins, as long as they alternate. The actual result is 15V less whatever voltage is lost across the diodes and bled from the last capacitor from the circuit it is connected to.

In practice, using Schottky diodes because they have a lower forward voltage than silicon rectifier diodes , I was getting around 14V.
