Hello, I picked up some of these from amazon. https://www.amazon.com/diymore-Display-Digital-Decimal-Segment/dp/B07MCGDST2/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1 It uses the TM1637Display.h lib for Arduino. https://github.com/avishorp/TM1637/blob/master/TM1637Display.h I Have tried all of the FC c...

I think I found it. It was the brown out detection. If I disable it it doesn't reset. Very strange.

Chad

I turned it off and it does the same thing. Power is stable and good. Totally disconnected the programmer and it still does it.
Hmmm

Gotcha, I did find something else strange. Just a simple delay loop about every second I get a glitch in the output.
You can see it on the scope trace.
And this is my program.
Any Ideas? Chad

Hi Leigh,

Actually I am running at 16mhz. I was hoping that I could just set the pwn down low and let the hardware take care of blinking the led while the program did other stuff. I guess I could get creative with a timer and counters or just do it with delays..

Thanks,
Chad

Thanks, I remembered seeing it a while back. It seems like that should be just built into the configurator?

I just posted a little pwm issue.. On to the next thing. . .

Yet another new chip;)

Chad

I am trying to get a 13hz pwm out of the 1501 Cant' seem to get it going at the right freq. I set my properties in the component and enabled it. I am using channel 4 that should be RA2. I can get a 1k out but it doesn't seem to let me go below that? The display in the component looks right? Any Idea...

Hey, I found that. What I couldn't find was the Internal Oscillator Helper. Got it all going.

I have another problem now but I will post that elese ware.

Thanks
Chad

* EDIT See above posts!

Hey, Just got the PIC8 Pack and I am playing with the chip and it looks like there are some config bit missing from the configuration.

Thanks,

Chad

I don't remember if you can have different fonts on the screen at the same time. I do know that there are many fonts to choose from. Here is the u8g2 font list. https://github.com/olikraus/u8g2/wiki/fntlistall . If you want to emulate a good display package this would be where I would start. https:/...

The way I look at it is if people are going to be using a oled or lcd they are going to be on a chip with a little more program space, or would be willing to bump up to a bigger chip. You aren't going to be spending dollars , tens of dollars on a nice display and fret over a single dollar for a bigg...

LOL, yeah I have a unique ability to pick hard to use things it would seem.
Right now my current experiment is with the PIC32MZ0512EFE064.
I'm going to need to be able to store some variables..

Chad

Sorry for the delay in responding. I have been really busy with work stuff. Been playing with stuff a little more, slowly sinking in. One question, why would you use harmony to instantiate a UART and not just use the FC component? Chad P.s. I ordered some of the little 8 pin pic's you like. Don't kn...

Is a version of this possible on a pic32mx?

Chad

Hey Steve, So it's been 9 years, how's that "looking into this" going

Chad

I agree, additional fonts would be really useful. The stock one Is kinda chunky..
Or at least a tutorial on how to import our own..

Chad

The https://littlevgl.com/ Is really cool. It would be a night mare to build it into a component.

I wish I was smart enough to get it running with my display somehow inside of flow code. Looks great!

Chad

Thanks, I'll give this another try!

CHad

Thanks, I'll give it a shot in the next day or so.

Chad

Thanks, for looking into the pin problem. I'll give it a shot.

Chad

Speaking as an ex lighting designer and someone who is also going to be using this, being able to adjust global brightness would be very nice to have.
Just fyi.

Thanks,
Chad

That's what I ran into on a hand full of components that I tried.

Chad

Thanks for looking at this. At some point I am going to be using a bunch of apa102s.

Chad

That is really interesting!. I have my chip running with the internal oscillator right now. I have been playing with the harmony configurator. I used it to help me figure out the clock configs then just changed them in the configuration in FC. I haven't figured out what files it generates need to ge...

Hi Qmesar,

Thanks for double checking this for me, it's nice reassurance that I wasn't loosing my mind, or what's left of it.
