So I take it you mean that you just stuff them in one byte at a time, and send floating point values using the PIC 4 byte floating point format?

Is it true that when you send the CAN message via th ...

Here are some of the answers that I have found while looking (with help of PCM Programmer's assitance...)

-Pull Up/Pull Down resistors not needed

-Max distance is 40 Meters for 1 MBit, and 500 m ...

Hi All,

I am currently moving my application from an RS-485 based communications system to a CAN bus system due to the benefits of CAN (such as arbitration, broadcasting, message resending, etc...) ...

I'm not sure what you mean by a 'refresh' routine in your post.

I am checking all the deta before it is being sent from the PC to the PIC, and I am checking it on the PC and on the PIC as well, a ...

I put the code onto a different microcontroller (brand new), and ran the same test and after 4-5 hours I had the same problem happening again.

However, doing the calculation, that does come out ...

I have a fairly length program, so I cannot publish it here, but my problem is this: My program is an RS-232 based program, and via RS-232 you can change the variables in the EEPROM, so to test the p ...

Is there an easy way to initialize them? Is there a function built in to do so?

Hello,

I have a function in my code that does some work with strings, and I declare two strings in the function (s

PCM,

Thanks for your post! I tried it with a T1_DIV_2 and that worked no problem. I just had to change the CCP_1 value to get the frequency to what it should be and voila, it worked perfectly. T ...

PCM,

We manufacture a finished product here and there is a socket where the microcontroller goes. I have simply switched the PIC18F252 to the PIC18F2620 and burned the HEX file to it. The circuit ...

Thank you rberek,

I am at a loss as to what the problem could be. I will e-mail the code to CCS tech support and see if they can get it working. If anyone out there has a PIC18F2620 in use and do ...

rberek,

I would appreciate that very much. I think version 3.242 would be fine to use it with. If you let me know the results, I would greatly appreciate it. If it comes out with a simulated 1.1 ...

Does anybody have a PIC18F2620 where they could test out the code that I posted above and see if they can get the 1.1KHz signal? I"m kind of at a loss at what the problem is. Also, if anyone else ha ...

newguy,

after you suggested it, I tried it and unfortunately it did not help. If you have any further ideas though, i'd be glad to hear it.

Thanks
