Thanks Max. Your version compiles and flashes OK. It is curious that the manual says goto's and gosubs are still permitted for backwards compatibility. Apparently they don't work in V2.5 Frankly programming without GOTO's is in my opinion contorted. Imagine assembly language without a jump to comman...

Thanks reply. Went to library management and "clicked" on onewire library. (How one knows it did anything is beyond me. No message that the library was included or anything) Compiler got further but failed in linking. Also an odd error related to a gosub line. 0 133 Compiled Successfully C:\dloads\t...

Just installed V2.5. Brought over a program run under Microbasic. 16F676 PIC The above error comment received. Code fragment: ow_Reset(PORTA,5) ' onewire reset signal ow_write(PORTA,5,$CC) ' issue command to DS1820 ow_write(PORTA,5,$44) ' issue command to DS1820 delay_us(120) i = ow_reset(PORTA,5) o...

Thanks. Will try that on 7.0.0.2 until I can find MB V7.2 somewhere.

It turns out that I have an old WIN98SE machine with MB2.2 on it.
The bootloader still compiles there. As a last resort, I could FLASH the bootloader on the PIC from there.

Well, the link on ME page to version 7 of MB is really 7.0.0.2 not 7.2. It compiles and flashes some of my existing programs OK. I tried compiling the bootloader for the 16f877A. It is identical to the above listing. This time a "Identifier 'Susart_Init' not defined" error was generated. It also tri...

Thanks Charlie. You have come to the rescue again.

Looking for link to version 7.2 of MB. The link in the reflector downloads 7.0.0.2. Is that it? I see the debug version is 7.3.

Brian

Yes, the newer version of Mikrobasic is one route.

My only concern is that I'll have to use a new version of PICFLASH that may or may not support an EZPIC3 board

Brian

Time marches on. Recollections get foggy. Some time ago I put an application on a 16F877A. It had a bootloader. I believe I was using MB 2.X at the time. The programmer is an EASYPIC3. Machine is XP-based. Since then I've upgraded to V6.0.0.0, have the application hex file generated. It successfully...

Instead of a two dimensional array would two one dimensional arrays work. That may keep them each in a given bank

I've had problems with rotary switches -- specifically debounce issues. (Normal pushbuttons and toggle switch debounce in software works just fine.) Not so with rotary switches for some reason. Problems were so bad that I had to add hardware debounce circuitry. Of course, this only happened when one...

If you care about the decimal places perhaps it should be 273.15

Brian

Those resistors probably OK. I was trying to minimize the current.
PIC's have a maximum total device current limit.

Do an experiment. Set the port pin high and measure the voltage with the device attached. See that it is OK.

I haven't a clue about the current the device you're using draws.

Try your SD card in some other device. I fear you have destroyed it. You can try a level shifting device called resistive divider to drive it. Perhaps 1.2k and 2.2k resistor in series. The output of the PIC goes to the top of the 1.2k, take the output to the SD card from the junction of the two resi...

Absolutely.

Working from the spec sheet, I'd never get it wrong!

It would be more instructive to neophytes if you gave the various OPTION_REG, ADCON, TRISX et all settings in binary. It would be easier to look up what they mean on the spec sheets. For example ADCON1= $82 is ADCON1=%1001000 In fact, it makes more sense to code them in the binary representation so ...
