I'm hoping someone might be able to help. I'm trying to modify software on a circuit that is using an 80 pin microcontroller that I have been trying to identify. At first, I thought it might be a Ti 185 series processor, but I'm not entirely sure.
I believe it's a TSOP package.
The numbers on...
Forgive me, but I'm trying to understand the problem regarding having different numbers of LEDs in each segment.
Are you saying that in a single 7-segment display, segment "A" may have more or less LEDs than segment "B"? If this is the case, why would you not simply be running 1 shift register...
I'll have to check that out. I have a real need to be able to precisely lay out my components, and include specific slots. Being able to start it in the mechanical drawing and move it into the PCB will be very helpful.
Being summer, these type of projects don't get a lot of my attention, but I...
What kind of code? Are you looking for the code for the subroutine to display? Your question is extremely vague, and people can not help you without knowing what you've already done and what you're stuck on.
EIhIS, thanks for the suggestion. I'm not sure those will work for me, though, as my display is RGB, so having the multiplexed display while also having PWM controlled on the anodes, may cause unwanted fluxuations in color.
I may give it a try and see how it looks. With spring here, I've been...
Mentioning gold sounds like you've been reading some of Kanzius' work.
Think about it this way: on a sunny day, what color gets the hottest? Why is that?
It's not just about metal. Any material works on the same principles of light absorbtion and reflection. If it appears darker to your eyes...
Thanks for the info. I'll check out the flip-flop and PicList.
I do need this to be pretty accurate. It's going to be used for calibration purposes, but it's not critical. a 5% margin of error isn't going to kill me, but I'd like to try to nail it. This is being used to calibrate a vechile...
I'm talking about software, because I want to be able to control the period of the PWM for specific, exact timings. Ultimately my program will cycle through 10 different settings, staying on each one for around 10 seconds.
I don't have frequencies, per se, that I need, but here are the 10...
Hello,
I'm trying to set up a simple program which will cycle through a set of specified time periods for a 50% duty cycle pulse. I have the calculations for the delay period, but I'm not confident on how to set up the program for accurate timing.
I have at my disposal currently PIC12F1501...
I am using transistors, but I was wondering if I should be using more. I will sketch up a schematic and post it ASAP.
I'm currently using 1 transistor per LED on the cathode side, but only one transistor per color output on the anode side, which drives all of the anodes in the LEDs for that...
I was afraid of that. Yes, the red always has a slightly lower current. I've never run into a multicolor LED that wasn't that way.
I just wasn't sure if I should be adding resistors or transistors. So I should be OK if I keep the single transistor to all of the LEDs for each color, but just...
I've been working on a project for a while, and making progress with it. However, I'm getting some results that I'm not happy with, so I'm looking for guidance.
To give you some background, this is an automotive project. I have many parts of my car's interior that light up which I've converted...
Personally I would have at least two emtter/receiver setups in the pipe as far apart as possible, so that as objects pass through, the microcontroller "sees" the breaks, and measures the time between them, then calculates speed.
If you can use at least two pairs so that the smallest object...
LOL
Read up on lightning. It happens when the charges become more imbalanced. By your theory of it eventually evening out, we would be having less and less lightning over the years because charges between earth and sky would become more and more balanced. However, it's always in a state of flux.
OK, I see where you're going with the TMR0. I was missing the fact that you're scaling it for the duty cycle.
Now I understand how it's working, and I'm wrapping my head around the whole program.
I think it's the +3 you have in the setting of TMR0 for the duty cycle.
I think I know what the...
