#104777 - thanks all, it's now solved. Responding to: ???'s previous message |
well... i finally find out i mixed TTL & CMOS in the same circuit (i used a 74LS373 as latch), and probably the 8051 is generating more noise than the ICE, so exceed the noise margin of TTL.
thanks all again. Chan. |

| 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 | |
| thanks all, it's now solved. | 01/01/70 00:00 |
