Thing is that they have it output at 600 hz which is high enough for most normal applications. It's just not good enough to use on video. I will contact them and see if they would be willing to modify the coding for me. Next, I'm going to run the signal through a microcontroller and output it at...
Buck converter.. Ok, thanks for the information. I'll certainly look into that. Do you think that running it through a microcontroller would eliminate that step? Since it would be outputting square waves anyhow?
That's a great idea which I've actually been working on trying out. The idea that I need help with is how to modify an existing driver to output at a higher frequency. We're in the process of developing our own driver but in the mean time I wanted to modify the existing ones to function better...
It's not really noticeable by looking at it unless you apply the photoelectric effect. The issue is with how the cameras record the leds. The image comes out as a wave moving down the screen. When I drive LEDS at 10khz the wave doesn't appear because its faster than the exposure of the camera.
I'm going to bump this topic since I'm still working on this project. I've found that I can eliminate the flicker if I can bump the frequency of the signal to 10khz. It outputs at 600 hz and is picked up by our cameras. I designed my own LED driver and when I output 10khz from the MCU its not...
Yea, its for an accessory and the product can't have extra wires hanging on it and were trying to avoid drilling into the products. I talked to RF Solutions and they said it's because the modules that I picked are "old" technology and that the delay would be significantly reduced with a better...
Sorry, I described that wrong. It's powered on constantly but remains somewhat 'inactive' unless the signal is detected. It's sort of a power saving mechanism. It has a 'sleep' mode but that turns off all of its functions but I'm not using that.
Let me explain what I mean by having to power...
It has power constantly and I don't use the SLEEP mode but... It does power on when it receives the data, which would explain why it responds quickly if i send a second single immediately after the first. How could I keep it alert and ready to go? I've tried constantly sending a signal on one of...
What confuses me is that it says that the maximum delay between input pressed and output asserted is 210 mS. That tell me the addition; 800mS is lost in the air or in the modules. Are you saying that it might be transmitting too much data through a slow transmitter/receiver?
I need to transmit a simple on/off signal a very short distance, like 1 ft. I'm using an rf600e/d set with a 434 mhz transmitter/reciever WRL-10534 . I have them wired up to a good omnidirectional antenna thats rated for 434 mhz. I have tested it over 200 ft and it works just fine. The issue I'm...
Here's the link to it on amazon ; http://www.amazon.com/Cooligg-Wireless-Controller-Android-Smartphone/dp/B00EUVDQL0/ref=sr_1_1?ie=UTF8&qid=1441838707&sr=8-1&keywords=wifi+led+controller. I'm using this and some LEDs. It looks like its being controlled by a MCU in the STC11F/10Fxx Series.
So it has a 16Mhz Crystal serving as the clock for a microprocessor which put its output as the LEDs. It's wired up to a couple LED Strips that total 42 small LEDS in Series. The Microprocessor can handle up to 36 Mhz, would increasing the clock help reduce flicker?
Hello ! I have a WiFi LED driver that we purchased that has visible flicker when its dimmed below even 80% using its own dimming software. What would you suggest for me to upgrade in order to remove the flicker? What would cause the flicker? In general, how can I improve on an existing driver to...
