The problem with learning about a cool chip like the LT8500, is that now I have YET ANOTHER project idea in my head! And I already have more than I can do! Very Happy

Weird, I use it all the time... never had an issue with it since v4.

Same here.

At this point, it doesn't really matter how many LED rows/columns/panels are being driven or what they are being used for. There's a lot of good information and ideas in this thread giving several ap ...

The great thing about the 74HC595 is that it has separate shift and output registers; so, you can shift the data in at your leisure, and then transfer it to the output registers in one atomic operatio ...

Good point, thanks!

Or should I setup the timer with a tick of maybe 1 second, and use an ISR to increment a 16bit counter and check it to see if it's over XX(seconds) and if so clear it and send the status message ? ...

The correct order is just to include the USB files in the same way as shown as in the examples and NOT to remove #includes within driver files Wink

Cool. Thanks!

If it's a mistake you think one of us might make, please let us know the correct order so we can not make it Smile

Thanks!

You are right that most solutions center on rechargeable cells. However, I know that Maxim and TI both make solutions for alkaline cells as well.

I agree with RF_Developer about the battery monitoring chip. That's the way to go. All of the projects I've worked on for the past 15 years or so have had a battery-backed cache of some sort, and we ...

I could live with 3.3v operation pic24/dspic33 but 4-5 ma per pin average won't cut it even for a led!

I usually use a ULN20xx/ULN28xx chip to drive devices that are mounted external to the circuit ...

As others have already said, it's tough for me to think of PIC32 as a PIC at all. If I ever need to move to something 32-bit, I will look at the ARM chips first. They are just a lot more widely supp ...

Or do it the easy way...
Look on page 56 of the current CCS manual under Interrupts.
There you will find Interrupt_Enabled()

DOH! Forgot about that one. That's what I get for answering in a hu ...

Hello All,

How can I examine is interrupt is enable or disable?
I use enable_interrupts(INT_TIMER1);, disable_interrupts(INT_TIMER1); to activate or deactivate it but I'd like to check is it on or ...
