Hi all, New post on Jallist (@Matt: I have sent the schematic diagram to you).
The PIC is programmed almost at maximum speed. It can even be a little bit faster since in the demo I erase both the flash and the EEPROM before programming but the latter was not required (saves 14 ms:-)). Since the 90 degrees rotated video was too disturbing I posted a new version which is rotated and I removed the previous link so also the reactions are deleted (sorry for that). Note that it is just a quick video to give you an impression. I am working on finalizing all documentation of the board and how to use it. Some other info. There are two PICs on this board, The first PIC is the controller PIC that does the USB handling, the command handling and the programming of the second PIC, the latter I call the application PIC. For the first PIC I used a PIC16F1455 and for the second PIC I used a PIC16F18857. The board is completely made of standard components so not using any Surface Mount Devices. This makes it easier to assemble. The application PIC does not use a bootloader but is programmed just like you do with a PicKit 3 so you can use a new virgin PIC for the application PIC. If you have more questions or requests let me know. On Tuesday, March 26, 2019 at 9:24:28 PM UTC+1, Matthew Schinkel wrote: > > Looks quite nice Rob, I like the quick programming.
