This simple circuit can be used to program the PIC16F84 and similar “flash memory” type parts. It uses a cheap 555 timer IC to generate the programming voltage from a +5V rail, allowing the circuit to ...

[Texane] wrote in to let us know he has implemented AVR ISP programming using a PIC microcontroller. He wrote some code for an 18F4550 that uses the STK500 standard for In System Programming. This ...

A while ago I received a package of hardware and software produced by eLabtronics in Australia. The company offers an ezSystem STEMSEL Inventors Tool Kit that includes a STEMSEL PIC-programming board ...

If you have an idea for a fairly simple USB device but don’t want to invest in the more expensive microcontrollers, this library will be of interest to you. It’s a software implementation of the ...

USB interfaces are everywhere today, with low cost flash memory drives and all kinds of USB peripherals readily available. But these are very much focused on the PC market. Attempt to make use of ...
