#105524 - the thread is about an emulator y Responding to: ???'s previous message |
your post is woefully incomplete missin:
chip you use means of programming it software used to generate the .hex the thread is about an emulator you posty about a simulator which is a totally different animal. So I decided to start with a very very small application such as blinking a led. It works on simulator as well , but the chip gives no response when I load the code. I have double checked all my connections , what the problem can be?? 1) for such a test use a "canned" software to rule SW problems out. Keil (and everybody else it seems) has a "blinky" that is avialble also in .hex which virtually guarantees that if there is no blink your hardware/program load is faulty. tru the following 1) scope the oscillator, is it running? 2) is the reset a) acive at power on b) gone shortly there after 3) is !EA tied correctly Erik |

| 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 |
