Today I made some more progress. I added support for more PIC18FxxKxx devices, so the total supported devices count is 305. There will not be much more of them.
I tested a few new ones, including PICs in TQFP package. Unlike for DIP packages, breadboard and wires are not enough, so I had to use TQFP adapter I made few years ago for PIC24 and PIC32 series, but with single cut trace it works for PIC18 too.
There is nothing more than micro and decoupling caps. By the way - JS09 really means year 2009. The time flies.
For this adapter I made simple testbench of perforated PCB.
With this one I tested PIC18F66J15, 67K22 and 67J50, each on its own breakout.
And this is gallery of all PIC devcies I programmed with this Arduino programmer. Every single MCU here has blink a LED program flashed. Much blinking power, very wow.
