Thanks alot, I'll check it out next week when I'm off break.

I looked at it before, and I wasn't sure quite how to change my code. However, now, upon further review, it looks like I should write my onewire_write function to imitate the write_byte function you ...

Hey all,

I'm trying to use a DS18B20 1-wire temperature sensor with a PIC16F876A, and I'm having some trouble with it. I'm using a board built by olimex, and then subsequently programmed by Paul H ...

Hi all,

I'm using the original code posted by Han Solo on the first page, and I can't get a temperature other than 85 C, which I think I read was the startup temperature. I'm using a PIC16F876A wi ...

If you get the PIC development kit, example 14 in the exercise book does exactly what you want - it uses Timer1 and an interrupt. Check it out if you can, its pretty simple.

What temperature sensors are you using?

Take care when copying code examples. The thread you refer to mentions the code is not working... Garbage In = Garbage Out.

Yeah but it was the latest post, which noone had responded to, so I tho ...

I'm not asking you to write any code for me, I've been trying to get my code to work for a couple days now, but I dont really know programming as well as the people on this board, so I thought I would ...

Thanks for the reply PCM, I looked at the thread and it seemed pretty good, the thing is, I don't really want to multi-task, my thinking is that a command is given to the PIC, and then it runs this fu ...

I am currently trying to use one of the internal timers for an application in my program, and I'm not entirely sure how to do it, I've searched through some of the topics but haven't found quite what ...

Hey man thanks alot thats flippin genius, haha, the program works better now, I can now read what comes into the buffer, so thats better. Unfortunately, its still not working as I want it too, as all ...

A minor remark:
Add the ERRORS directive to the #use RS232 line so the compiler adds code to clear some common errors. Very unlikely, but if your program is slow in reading the UART the UART will sta ...

I wrote the messages into an external EEPROM chip that came with the development kit I go, and then read them with another program, and apparently all the PIC received from the modem simulator was a n ...

The simulator was created by someone else, someone who presumably knows what they're doing (unlike me :p), and it is on the computer. The company I work at uses it often for their products, so it see ...

oh yes, of course, sorry about that, here are the protoalone.h and utility.c files.

protoalone.h:

#include <16f877A.h>
#fuses HS,NOLVP,NOWDT,PUT,NOPROTECT
#use delay(clock=20000000& ...
