Hi
I am currently in the middle of a project with the 8051 and i download my hex files onto the uC via Atmel's Filp software.
For some reason today the flip software just stopped working, giving me 'Timerd out' everytime i try to download to the uC.
The programming secquence on the uC that i use is to press RST and /PSEN together, before releasing RST first then /PSEN.
ANy idea why it stopped working, What voltage reading should i get on the /PSEN pin when its switch is pressed. My circuit on the /PSEN pin is simply a 10K resistor followed by a push button switch which is then tied to ground.
