#102950 - ISP Help -T89C51AC2 |
Hi, I Have built a circuit containing an Atmel T89C51AC2 uC. I have built the circuit planning that I could use the ISP (using flip) to program it which I’m not have much luck at doing. My problem is when I try and use flip to connect to the uC I always get a timeout error. I have checked the circuit which it all looks correct. I’ve had a search around the site but can’t find much information about my problem. I have used the debug mode in flip which shows some information:
***** ispSelectCommHardware ***** ***** ispOpenRs232Port COM1 9600 ***** ***** ispSetAutoIsp ***** ***** ispSetRtsLow ***** ***** ispSetDtrLow ***** ***** ispSetDtrHigh ***** ***** ispSetRtsHigh ***** ***** ispSyncTarget ***** 1 >> U 2 << U ***** ispReadSpecialByte BOOTLOADER_VERSION ***** 3 >> :020000050F00EA ***** ispSelectMemory 0 ***** ***** ispGetLastError ***** ***** ispSelectMemory 0 ***** This is as far as I get. Any help will be appreciated Thanks Cameron |
