Thanks for the FF 5 hint.

But please check it. Some stand alone programming software will override the configuration words if the option is enabled. Thanks for the FF 5 hint. I charged the battery and added a capacitor tried with 0.

Essentials Only Full Version. I’ve tried 3 of them, but all have the same behaviour. Thanks in advance, Lorenzo P. First post, so please be patient Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Forums Posts Latest Posts. Although a lm780a5cz pain, I’m going to check that they don’t mess up configuration section. Is the 10F too young to be used for a non-hobbyist proect or can I consider it stable and somewhat tested?

Well you may have analog features set by default a common one in Microchip at your pins, I am not sure since i don’t know much that PIC of yours. I searched the web for the template code for 10F, but I haven’t found anything yet.

The second program works, the first doesn’t. Still that should not affect the outputs, usually In the simulator it works like a charm. After that it talks about the read-modify-write problem, which shouldn’t affect the test code above. What am I doing dqtasheet When I programmed a 10F for testing, it didn’t work, so I decided to try a basical “Blink a LED” program to exclude hardware problems.

The night hasn’t been long enough for me daatasheet point out the problem. The reading before the was about 8. Is there something I am missing? Well you may have analog features set by default a common one in Microchip at your pins, I am not sure since i don’t know much that PIC of yours. This might be a cut-and-paste error, or a HTML formatting error.

Why does my PIC32 run slower than expected? The reading before the was about 8. Still that should not affect the outputs, usually This is wrong, and would lead to daft behaviour. I’ve always thought that a battery power source was clean enough for prototypes the real application will use a capacitor transformerless power supply, which scaries me a lot if the project isn’t working from a battery power source!

After that it talks about the read-modify-write problem, which shouldn’t affect the test code above. M Super Member Total Posts: I have written a firmware for a twilight switch, no errors from compiler and linker.

I forgot to mention that I think pin RA0 isn’t oscillating, since I tried to measure the frequency with my multimeter I don’t have an oscilloscope, but I think I’ll need one somewhat soon and the reading was 0 in both scales 2kHz and kHz if I remember correctly.

Not so good from a rechargeable “9V” battery that typically has a nominal output voltage of 8. Another thing I’m going to try is to set a different oscillator speed. You should still have decoupling at the PIC.

Looking at your delay code as postedI see “goto 2” after the first decfsz and “goto 1” some lines later. Forum Themes Elegant Mobile.

Is there something I am missing? Your symptoms act like the chip is not running I wonder if the PIC is running at all and, then, about your hardware: The best would be to have different productions, but I think I’m missing something on the software side.

Thanks in advance, Lorenzo P. You would probably do better to use 3x 1.

Anyway, I’ve just modified the code and that doesn’t work. Since I have to write a thesis, any help would be greatly appreciated. Keep i the regulator – PIC connection as short as possible, and you could get away with 2x 0.
