Hello, We use the onboard PLL to multiply up the 8MHz input clock frequency up to 140MHz. Unfortunatley you currently have to do this using C code. //Setup configuration for 70MIPs using 8MHz Crystal PLLFBD = 68; // M=70 CLKDIVbits.PLLPOST = 0; // N1=2 CLKDIVbits.PLLPRE = 0; // N2=2 OSCTUN = 0; //Tu...

Hello Fernando,

Please can you post a project that demonstrates these problems and I will investigate for you. The changes on both of those properties should be immediate and not require a reload of the project.

Hello,

Yes if you copied one of the existing K42 FCDX files and changed the pins and other sections to match the device then that should work. I'm a bit wary of adding more K42 device support at the moment as I know there are problems with these devices which we are slowly wading through.

Hello,

I've had a look for you and that is a puzzler, hmm. I'm not aware of anything that might cause this and looking I can't spot anything obvious.

I'll think on it.

Hello, I've had another look at the code compared to what you posted and it all seems to look ok. However it appears the clear function is not working for some reason. Do you know the pixel dimensions of your display? It might be worth trying to increase the pixel height in the component properties ...

Hi Chad.

I looked at the datasheet on the driver ic sk6812 and there were only three colour channels. Is the white led part of the same led package or a separate package? Do you have a datasheet for the white led?

Hello,

Please can you try the new component file I've pushed to the update system.

Hopefully this will clear the display and if that works then I know how to fix the pixel functions too.

Let me know how you get on.

Hi Lagoda, I'm doing some more investigation for you now. I may end up buying one of the ICs so I can test here. Are you programming the IC directly with say a PICkit or do you have a bootloader loaded on the IC? Just wondering if we can trust the config values being assigned by Flowcode. It might a...

Hello,

Here's the component source, please let me know if you find anything. It looks like maybe the initialise is ok but the clear is not working correctly. Maybe to do with the GotoXY function.

Hi Chad,

It looks like it should be compatible.

Have a go and let us know how you get on.

Hi Lagoda, As your delays are off that indicates things aren't setup correctly and the MCU likely isn't running at the speed you think it is. The first thing to focus on is getting the delays correct. Some advice here on testing and things to investigate. https://www.matrixtsl.com/wiki/index.php?tit...

Hello,

In your case it would look like this.

Hello, We recently fixed a long running bug with the reference voltage setting on the Arduino Uno / 328 / 328P devices. Before the settings the user selected was getting switched and potentially corrupted whereas now it should be correct. Check your ADC component property settings relating to the AD...

Hi George,

This topic should help.

In your case the union could instead look like this.

Hi Lagoda,

Thanks for the files.

How about changing the LED type property to custom and then reducing the T0H timing, maybe to 0.1 and see how that works.

I'll investigate the delays being wrong here on the hardware I have available.

Hello,

I can't solve the FAT problem for you but the RS232 and I2C components can be used for free by using the hidden CAL version of the component. It's not as polished but it might enable you to proceed.

Hi Lagoda, Do you have any high speed interrupts running that could be causing timing issues? Interesting the delays are out, these should be fairly tight. What is your T0H timing currently set to? This is the one you need to bring down if possible, the other all look to be in tolerance. Can you pos...

Hello,

Very sorry for the delay, it should be there for you now for the Q10 devices.

Hello,

Yes it looks like your project is missing components. Which version are you using and can you use the 30-day trial.

If you load the project into v9 then you can re-start the free 30-day trial and get access to everything.

Sorry link here.

Glad you've gotten somewhere with it now.

Hi George,

I've just tried it here and it's working ok for me.

Have you applied the fixes listed here?
https://matrixtsl.com/mmforums/viewtopi ... 63&t=19743

If you have and you're still getting the problem then please can you attach your .fcfx project file and your .msg.txt error log file.

Hi Lagoda,

No problem I've rolled it back for you. Thanks for letting me know.

Hello,

Excellent that's great progress. I've now pushed another change to hopefully better work out the baud rate.

Let me know how you get on.
