PICSTARTPLUS much faster rate than programming.Ĭan easily read the contents of the chip program area.Ĭomprehensive information prompts, allowing users to understand the working state. No external power supply, communication and power is only a USB cable to print complete, without any cable. The modification is built around another cheap ebay purchase.Support the most popular programming PIC chips, read, encryption and other features! RTD, TXD and DTR and all I needed to do was to supply a TTL level serial signal to the PIC 16F628A chip that is the heart of the K150 and I could bypass the troublesome Prolific PL2303 altogether.Īlthough I could have cut a few runs on the board and attached some leads I decided to build a daughter board that would plug into the socket for the PIC 16F628A. One day I was scanning the schematic for the Peter Crowcroft version of the programmer (I was unable to find a schematic for the clone versions) and I noticed that only 3 signals came from the FTDI/Prolific chip. Then Windows 10 came along and it was nearly impossible. With each new version of Windows it became more and more difficult to find a driver that would run correctly. I seems the Prolific wasn’t happy about unauthorized copies of it’s chips being sold so they added code to their drivers to detect the illegal devices causing the driver to fail to load. The problem you see is that on these clones, the FTDI USB-Serial converter chip was replaced by a cheaper PL2303 chip by Prolific Inc. Printer ports and Serial (COM) ports disappeared from most PCs long ago.įor quite some time things were fine. I started out programming Atmel AVR chips because at that time, all you needed to build a programmer was a cable that was wired to your PC’s printer port.
Quite a few years ago I purchased one of these and a few PIC chips to learn how to program and use that line of microcontrollers. These are modified copies of the K150 programmers by Peter Crowcroft. You may have seen these dirt cheap K150 programmers for PIC microcontrollers for sale on ebay.
