I am probably the 100,000th person to have this problem.
I haven't used my proto board for some years, but it is working with Stan's single digit thermometer. All the programming links are in place, the cable looks OK.
Pin 2 Serial goes to leg 7
Pin 3 serial goes to the junction of the 10k and 22k resistors, 22k goes to pin 2, 10k goes toGnd
Pin 5 Serial goes to Gnd
I am using the following:
Asus laptop with W7 64bit
PE 5.2.10
A USB-Serial cable of which I have a few.
Its quite a while since I programmed, probably on the old Toshiba/Vista machine which was replaced a year ago.
The PE (and Device Manager) finds the cable on COM12, and testing the port shows 0V and 4.5V on Ser in pin 2.
When I try to download to a 14M with the power off the chip, I get the message about missing h/w, etc after about 5 - 10 secs. If I apply power straight away,I get an error message
"Serial port error - code 0X1F54 'Error reading comm device'
I say "Why the 0xFFFF doesn't it work?"
