I got that, I read some papers and they count very much on rise and falling time, measured in V/micros. I know what you said. |

I got what I want: to see how hard is to build a PIC programmer. Maybe, someday, I will be still alive and I will try to build something. Maybe Microchip will keep the same PICs on the market, just to be able to test my programmer ..... Thanks guys for your posts, but I must stop here with my questions and find more answers in the documents. |
