Yes I agree, those corners look a bit wonky.

If you have time I would love to see some smooth scrolling macro :) If possible, it would be great if one could specify which coordinates or at least which Y lines that should scroll, direction and speed. Scrolling text one pixel column at the time instead of a whole character per step is just so mu...

Ok, got it. 90 degree corners sounds interesting. Could be used to do nice rounded corners on boxes etc.

Thanks Ben! I am actually ok with using a small square as degree symbol for now. Looks alright. What do you think about the circle drawing macro? doable? And yes, I thought it would be best if you had a display in case there are other issues down the line or new features to be added to the component...

Yes I have seen that but I don't want to cut off the number, I need to round it.

And you can keep the display I sent you. This works so well that I'm buying plenty more

Btw, how would you suggest I go about printing the degree symbol on the display? I suspect that I cannot use an ASCII code since there are no ASCII tables in the display controller?

For now I just draw a small square 3x3 pixels but a circle macro would be nice

May I ask if it is possible for you to implement a macro for rounding a float to a configurable number of decimal places? Since the calculation function: fround$(float,int) doesn't work for PIC with the compiler supplied. I have posted on the forum over at the website of the company that makes the c...

YES!!!!

That's what I'm talking about!!!!

This is how all displays should look! It's like real time updates now, 2000 FPS at least!

Here's a video of this in action: http://youtu.be/DpOzX6RyuAk

So nice!

And here is another video of the SSD1306 with font "0" to demonstrate the speed difference:

Thanks Ben, I will have a look, but I think I have used 3 or 4 wire SPI for my SSD1322 displays but as I can use 8080 or 6800 (at least on the 5,6" one) I guess I can try it at least. Which is faster? In the meantime I have tried the SSD1306 today. Here is a small video: http://youtu.be/j3IWRx3rd80 ...

Yes, both breadboards are powered by the same power supply an thus have common ground. I have also tested the 1 second LED stuff. It works fine. I am almost certain that I am doing something wrong with the CANbus stuff. But all I really try to do is to send TX buffer 1 which contains a message of 8 ...

Thanks, it just makes more sense if the properties and the chip configuration were connected. And I have read that information about CANbus but I still don't feel that it explains how the filtering, masking, message IDs etc. works. I mean, I do understand the basics of how it works, where a message ...

Crenwick, could you please try the alarm functions as well? I cannot seem to get them working. I have tried both alarms, and many different settings but still nothing.

Have you programmed the chip with a time and date?

Do you have a battery backup for the chip? Otherwise you would need to program the time and date every time you power up the system.

I suspect that it might be a memory limit causing this on the hardware you are using but I did change your program if you would like to try that as well. I don't think it will work on the two PICs you are running. So if it still isn't working, could you try it on some newer chip with more RAM?

For PIC's please try this:


Float_Variable_01 = pow (10.0,2.5) This would be 10^2.5

Float_Variable_01 = pow (2.5,10.0) This would be 2.5^10

Float_Variable_01 = pow (Float_Variable_02,Float_Variable_03)

That is working for me.

I am trying to get CANbus working and since I use PIC18F26K80 for a few other projects I thought I would use it for this as well. In the project options there's an option for changing the pins for CANRX and CANTX. Either RB2 and RB3 or RC6 and RC7. But if the RC6/7 option is selected, the properties...

With 1.6 the dashboard "icon" showed the original I2C icon with the DS3231 name, but had the LCD icon "stuck" under the I2C icon :) I'm going to use the alarm function to wake the PIC up from sleep mode at precise intervals, when the alarm function is working that is ;) John, if you want I can make ...

I use Diptrace as it was the only PCB design application that was intuative enough to just "get going". It has become better and if you use all parts of it, component creation, pattern creation, schematics and finally PCB design, then it is really nice and easy to use. And the newly updated 3D featu...

If I was correct this weekend there is a bug with clearing the Alarm Interrupt Flag and instead of writing a 0 it writes the retval which is 1 if the alarm has "gone off". But it is an interesting idea that John had. Maybe the CheckStatus macro could have a function to read back the Alarm Time regis...

I guess you know your stuff :) I can now send data in 1,5-2 second intervals (might be able to push it higher but there's no real point in super fast updates using GPRS) I usually don't forget to disable the "Extended Instruction Set" but sure enough :) THANKS! :) |date_record |temperature01 |2014-0...

Just thought I would let you know that I sent you my 0.91" LED SSD1306 yesterday.

Here's a photo so you can see the pin-out legend

I'll try again but when I tried it with PIC18F4550, exactly the same program, I had the "Extended Instruction Set" disabled.

Will let you know once I get home.

Hi Ben, I'll send you the program file in a PM. There is no macro for the GSM component to un-initialize it, as I found out when I thought I would just do that after the data was sent. I have tried this exact program on both the PIC18F26K80 and PIC18F4550 with same results. Thanks for checking my pr...
