Good point Jerry
Will do as suggested.

I see nothing wrong with getting two or three different opinions on same subject or project issue. If this is an issue well I am sorry if I offended anyone. I take and try out EVERY SUGGESTION just to see what and why a piece of code does this or that. Yes I copy and paste code just to get an idea w...

here is the complete code. I added the config BOREN = off and looks like it fixed the freezing up issue. Thanks for looking at it. I need to research what Boren is, something to do with low operating voltage?? ' 8x8 RG Matrix Scrolling text test ' PORTB = RED LED Cathodes ' PORTB = GREEN LED Cathode...

this code freezes up after one run through the code but only when using battery power. runs fine if the pickit2 still connected.using an 18F24K20 pic const array has 112 bytes. compiler says 512 bytes program bytes used and 42 variables. I am thinking its a memory issue?? but it should still freeze ...

purchased a refurb from Newegg and trying to get a price match.
Found same at Staples but Newegg says it is not the same but it is.
Even had my son in law who worked for Best Buy geek squad look at the two.
Good price on a Lenovo w/ 500gb HDD for $274

Thanks Jerry
looking at a refurbished Levano from Newegg for $150-$230
Have never had an issue w/ refurbished stuff

After moving to Washington state and finally getting settled in I am looking at getting back into pic programming but need a laptop computer to do the deed. I figure after Christmas sales etc would be a good time to pick up a good refurbished win 7 laptop but which one and how much memory. Have no r...

More than one opinion is better to figure out something than just one opinion. There are several methods to solve a problem so asking different forums helps. No one has all the right answers.
And yes Jon has helped a-lot as has other people.

Ah yes I think I get the picture?? At present I am latching after each two bytes ( after each 16 bits I am calling sub WRITE_MATRIX) SUB Write_Matrix1() Load_pin = 0 Data_out2=256* Display_Reg + Display_Data shift.out (MSB_first,Data_out2,16) Load_pin = 1 END SUB Hopefully this will lead me down the...

I have the MAX7219's daisy chained using one Din for eventually all 4 matrixes but going in steps. Got one working but getting the second to display the correct data. The data sheet says to address the NO-OP register after each write command per matrix (3 matrixes 3 address to options or display reg...

I did all that you explained. Got one letter to appear on the matrix correctly and scrolled it across the matrix. Just seems like alot of code but that's the way it is. Was trying to do similar with the Max7219 as I did with just a matrix driven off a pic as my second code I posted does. Just a few ...

Purchased several of the MAX7219 / 8 x 8 matrix boards and with help from Jon finally got one working. Well looking at several code examples for Ardunio using two dismensional arrays and a scrolling module. SF dosen't have two dimensional arrays but maybe someone has come up with an easy method to s...

The problem that I had reading multiple sensors but the program would not output more than one sensor was apparently due to the software uart. I tried using the hardware uart and all is a go. WHY?? at this point I am moving on with this project. I now need to concoct a math formula to determine refr...

Thanks
I was considering doing something similar but by testing and noting ID of each sensor seperatly. Using the OW search helps a bunch.
Will give it a whirl

I tested the two sensors and both work using same multiple DS18B20displayall.bas code sample. Ran code with only one sensor connected and both sensors output a temp reading and different ROMID #'s (sensors bought on Ebay) When connecting both sensors only one reads. Using the software UART. Changed ...
