Re: LDR (Light Dependent Resistor -> FC V8

Many thanks for all the help! I appreciate this very much. There is one more thing I would like to see in the flowchart. I can't think of this. It would be nice if the LDR could be read once per minute and the average value calculated within a period of, say, five minutes. This value then goes to th...

Re: LDR (Light Dependent Resistor -> FC V8

Hi,

I have done it by this way. I will use CO, C1, C2 and C3 for PWM 1 to 4. The mosfets are also connected to these PIN's. This works great now with one mosfet on C0.

Re: LDR (Light Dependent Resistor -> FC V8

Thanks. Great information ! I don't see any changes in the posted flowchart. I have it working now with one mosfet and via this way: PWM1 and the mosfet ( -> LED Lamp ) are now both on C0) Set Duty Cycle of PWM1 to ADCvalue Wait one second Set Duty Cycle of PWM1 to zero Wait one second Repeat This n...

Re: LDR (Light Dependent Resistor -> FC V8

Hi chip fryer27, I'm sorry I didn't respond, but I've started all over again. I hope you are still present in this forum. The LED Drivers work but not well enough whether it is 700mAor 1000mA. Both are not good. Technically this works well, but this is a very expensive solution. I therefore started ...

Re: LDR (Light Dependent Resistor -> FC V8

The target chip is an: PIC16F18346
ADC is 10Bit

The LDR is an NORPS-12 - https://www.farnell.com/datasheets/3759787.pdf

You have my schematic and the flowchart is above in this topic.

Thanks !

Re: LDR (Light Dependent Resistor -> FC V8

Hi chip fryer27, Thanks for your reply. The reading of the LDR will indeed be once every 2 minutes in a later flowchart. Constant reading does not make sense and will certainly affect the entire operation. I also understand your thoughts about daylight, clouds and night. But this is also not very cl...

Re: LDR (Light Dependent Resistor -> FC V8

Thank you!! Isn't it true that in Flowcode you can reverse the reading of the LDR? Then would be nice. The lamp must of course burn fully in daylight. When it gets dark, it should dim. From 100% to about 60%. The LED Driver RCD-24-1.00 goes up to max 1050mA so really too much. EDIT: 1000mA PWM shoul...

Re: LDR (Light Dependent Resistor -> FC V8

I'm also looking at the RCDE-48-1.05. It has a common PIN for “PWM DIMMING AND ON/OFF CTRL”. This is half the price of the RCD-24-1.00. Recom also suggested this to me to use.

So it would be nice to be able to use this shared PIN for brightness and on and off.

Re: LDR (Light Dependent Resistor -> FC V8

I've come a bit further with this LED Driver. I started from scratch with both the schematic and the flowchart. I am now using the RCD-24-0.70 (max 700mA) for testing. The LED lamp has a specification of 12V/940mA. So far it looks perfect. No more flickering. I used the following ports of the LED Dr...

Re: LDR (Light Dependent Resistor -> FC V8

I just made a video with the LED Lamp and a LAB power supply. If I turn back the current, the lamp will burn less brightly. This without flickering.

So this could be the solution.

Re: LDR (Light Dependent Resistor -> FC V8

I would rule out the LDR as the source of the fluctuations and replace it with a potentiometer, just in case the LDR is not providing a constant resistance. If the flicker still exists, then I guess it's the switching of the LEDs or their drivers that is causing the issue. Maybe consider driving th...

LDR (Light Dependent Resistor -> FC V8

As a result of this thread, I'm going to ask the question here again. https://www.matrixtsl.com/mmforums/viewtopic.php?f=63&t=19023 Because I have Flowcode V8 I was advised to continue posting the question here.

SK6812 RGBW LED strip 5M and 300 LEDs

I have a SK6812 RGBW LED strip 5M and 300 LEDs.

I want to use this strip with two PIR sensors and must only work when it gets darker.
Does anyone has a working .fcfx file for this LED strip ?

Thanks,

Hi Martin, Many thanks for this 32MHz and 4x PLL idea. Indeed the buttons are reacting much more faster. There is only one last problem what I have in this code. That is about the manual switch.

Hi Martin, I have taken your code from the LTRS 15 into my code. Now the total code is running very slow on hardware. I have disabled the decision “ResultFloat > 7.49” and it makes no difference. So, the slow running comes from the Component Macro “ResultFloat… “ and the Calculation icon “CurrentStr...
