The night hasn’t been long enough for me to point out the problem.

In the simulator it works like a charm. Your symptoms act like the chip is not running 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!

What am I doing wrong? Is is possible your configuration words are being overwritten by the programmer? I added a “clrf WPUA” instruction but, as expected, it does nothing. Still that should not affect the outputs, usually Forum Themes Elegant Mobile.

I have read the But please check it. 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. Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Since I have to write a thesis, any help would be greatly appreciated.

Looking at your delay code as postedI see “goto 2” after the first decfsz and “goto 1” some lines later. You would probably do better to use 3x 1. There are only 10 types of people in the world: I have written a firmware for a twilight dagasheet, no errors from compiler and linker.

Another thing I’m going to try is to set a different oscillator speed. Thanks in advance, Lorenzo P.

OK, I’ll try to add a capacitor, but I still think there has to be something else The reading before the was about 8. What am I doing wrong? Not so good from a rechargeable “9V” battery that typically has a nominal output voltage of 8.

The voltage at the battery under load is 9. I wonder if the PIC is running at all and, then, about your hardware: 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.

Essentials Only Full Version. After that it talks about the read-modify-write problem, which shouldn’t affect the test code above. Not so good from a rechargeable “9V” battery that typically has a nominal output voltage of 8. You should still have decoupling at the PIC. Is the 10F too young to be used for a non-hobbyist proect or can I consider it stable and somewhat tested?

User Control Panel Log out. Thanks in advance, Lorenzo P. 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 datsheet 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. I have read the I’ve tried 3 of them, but all have the same behaviour.

Thanks for the FF 5 hint. M Super Member Total Posts: Keep i the regulator – PIC lm7805qcz as short as possible, and you could get away with 2x 0.

Good suggestion for the configuration word. I charged the battery and added a capacitor tried with 0.

You should still have decoupling at the PIC. Anyway, I’ve just modified the code and that doesn’t work. You would probably do better to use 3x 1. Well you may have analog features set by default lm7850acz common one in Microchip at your pins, I am not sure since i don’t know much that PIC of yours. My troubles start in the real world.

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. I have written a firmware for a twilight switch, no errors from compiler and linker. 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!

Haven’t received registration validation E-mail? The best would be to have different productions, but I think I’m missing datassheet on the software side. I searched the web for the template code for 10F, but I haven’t found anything yet.
