Hello all, has anyone tried to wire up serial to Usb, is it possible.
Ive just bought a new laptop darn it old one was perfect gave it away.
My new laptop has no serial port and no cd tray, hence the dilema, is there anyway to connect K8048 through usb or am i gonna have to defect to pickit2.
Any ideas would be gratefull.
Thanks Arif.
cant you use a USB to Serial Adaptor?
I recently used one of these to connect the K8045 kit to my laptop via USB.
No you can’t use it.
The experiment programmers 8048/8076 works only with a real serial port.
for USB programming please use our PICKIT2 ,…
Thanks all for the speedy replies i tried the usb/serial cable but it doesnt work, i guess the data lines in the usb arnt correctly setup with the serial end.
I shall have to go for the pickit2, thx again for the info.
yours gratefully
Arif.
PICs are programmed serially with both a clock and a data line. This requires two fast and predictably timed pins coming from the programming PC. The PC software for the K8048 can make “true” RS-232 ports do it, but USB converted ports likely don’t reliably reproduce the required timing on the 2 pins used (RTS and DTR). The regular data pin is used to turn on Vpp.
