Re: [Usbpicprog-technical] firmware 0.4.1 and P16f88

[Frans S. <fra...@gm...>]

Dear Jasper Wallace,

Have you tried firmware 0.4.0 with software 0.4.1? If that is true, I
can rule out the software for bug tracking.
I was getting a similar message about the 16F87XA. It doesn't
autodetect, but reading / writing is fine. The funny thing is that the
autodetection method is just the same as reading the code memory.

About the 16F1827, it will be possible, but a Zener diode of 8V or 9V
will be necessary on the target board,
For the LF versions, also a 3.3V regulator will be needed.

Kind regards,

Frans Schreuder
