Usb to serial converter for pic programming
January 21, 2013
Hi.I have a pic programmer (pic 16f877a) with rs232 adaptor.I program the pic with the serial port of my pc
and i want to make it usb but still programming it with serial way with low voltage programming (no bootloader)
so i will connect the usb port to my pc and the output rs232 with the rs232 of my pic programmer.
I think i need a usb to serial converter chip like FT232xx and a hex schmitt trigger inverter to be able to send hex
files to pic.
I have found some schematics but most of them are not for programming and i am a little confused.
If you have a schematic for this converter please post it.Thanks
