btw: i just notice i had a 74LS373 latch in the circuit, but all other chips are CMOS, so i am guessing it may be related to he logic level problem, but since i don't have any 74HC373 at hand, before i go to buy one, i would like to ask how big is the chance that the problem is related to the 74LS373? Could be. LS parts aren't rated to work at 3.3V. -a |

| code works in emulator, not in 8051? | 01/01/70 00:00 | |
| well a simulator simulates | 01/01/70 00:00 | |
| Check CCT | 01/01/70 00:00 | |
| you talk about an In Circuit Emulator | 01/01/70 00:00 | |
| Actually it was an emulator | 01/01/70 00:00 | |
| OT: emulator, name | 01/01/70 00:00 | |
| now we got over the fun, I'm glad to pro | 01/01/70 00:00 | |
| not the code size | 01/01/70 00:00 | |
| (un)initialized SFR/RAM? | 01/01/70 00:00 | |
| may be, find something strange!! | 01/01/70 00:00 | |
LS vs HC | 01/01/70 00:00 | |
| i will check the stack | 01/01/70 00:00 | |
| Check your UUT first | 01/01/70 00:00 | |
| probably not the stack | 01/01/70 00:00 | |
| sorry... by "emulator" i mean ICE | 01/01/70 00:00 | |
| Do some simple checking first | 01/01/70 00:00 | |
| same problem... | 01/01/70 00:00 | |
| the thread is about an emulator y | 01/01/70 00:00 | |
| led is blinking now ;) | 01/01/70 00:00 | |
| you got a REAL problem | 01/01/70 00:00 | |
