Re: CAN Component - Buffer
Just checked last nights work. The CAN interrupt will only run if CheckRx is placed in the main loop. If the main loop is slowed down by a 500ms Delay, the interrupt will only run at this rate. So I am fairly sure Check Rx is toggling some bit thus activating or deactivating a larger part of the CAN...

Re: CAN Component - Buffer
Ah... I may have missunderstood.
If I place the CheckRx macro in the main, then the interupt will run.
I assumed it would have to be in the Interrupt routine.
Does this make sense that it works with the CheckRx macro in the main loop?

Re: CAN Component - Buffer
I assume
ts_Bit = test Bit.
st_Bit = Set bit
cr=Bit = Clear bit
and these are little macros dinfined in the compiler or FC ?

Re: CAN Component - Buffer
Hi, As suggested I tried inserting the CheckRx macro but this did not change the behaviour, the interrupt still does not run. Any further thoughts? Or could you supply the interrupt code you are using and I'll try to play around with it as a custom interrupt. I tried making my own custom but its on ...

GLCD Touch Screen Example - Keypad 4D uLCD-32PTU
Just sharing a basic working example of the using the Touch Screen of the 4D Systems uLCD 32PTU as a Keypad for inputing user data. I needed to allow the user to input some values, this example is visually pretty crude but works well in hardware. Not all keys are enabled and I currently only use it ...

GLCD - Writing and Clearing Text of varying length
Hi, I am writing a string to a GLCD, I have the Transparency set to 0 so any new text cleanly overwrites the old text. However if the the length of the string is shorter then the previous text, the last few characters of the old text remain. With a conventional LCD I would simply preceed any new tex...

Re: CAN Component - Buffer
Any Thoughts?
I should be able to clear some bench time next week to progress this if there is anything to test. Thanks, John.

Re: 4D Displays - Basics
Great, Thanks Ben.
I've managed to get both methods working in a basic fashion.
Where I have previously used my display, to make the screen work as a basic GLCD I needed to load the Screen with the (serial) PSE program from the 4D software.
Thanks, J.

4D Displays - Basics
Hi, I'm hoping to tackle the display requirments for a customer project and I've been meaning to do more with the 4D displays. In Early FC examples by Jon Crow..the graphic widgets were setup in 4D software and loaded to the screen. Commands were then sent/recieved from the PIC. Visually complex wid...
