Thanks for the answers. I have time on Friday to check this is FC7 and see the memory details then. Chancing from chip is not a problem. ( I must make new PCB’s because the shape must be modified)

Can I run FC7 and FC8 together on one computer without conflicting each other ?

Hi. There should be no difference between XC8 and XC8 in V7 and V8 My wild guess is you ran out of memory on the chip Hi, I’m sorry but this is the same chip. There is really no hardware change or program change. Just FC7 to FC8. The program was made on Nov 15 2017 and successfully compiled with FC7.

I’m trying to build a hex file from an earlier made .fcfx program. I have made a hex file from this program but in FC7. Now I have FC8 and I can’t get built a hex file from this .fcfx file. I have not changed anything in this file. It is still original. I assume it has something to do with “space”. ...

Hi Martin, I’m working on it. But I have also to do other things in my job. But in the meantime I have built the mosfet part on the separate breadboard on a new better breadboard. Suddenly two mosfets where dead because of a short in the old separate breadboard. (see YouTube) Your “LDR TEST - 4 PWM ...

I have done some measurements and came to the following conclusion. (Measured with a SDM 3055) The power lines have thick wires, not breadboard wires. I have only test it with 1 channel. I need in daylight 12V on the LED Lamp. If you look to Table 3 than the LED Lamp gets only 10V because the Gate f...

Hi Martin, The program “LDR TEST - 4 PWM component.fcfx” works on all the 6 outputs including 3K3 resistors on the PWM line :-) But when I dim the LDR the LEDs starts to flicker. On the 5mm LEDs you can’t barely see it but the bigger LEDs clearly flicker. They do this all the time. In 100% brightnes...

Martin,

Thanks !

Last Saturday I have tested your “LDR TEST - 03.fcfx” and It works as you have designed.
I have made a video from it: (on my garbage / test channel on YouTube)
https://youtu.be/wz4fTK4Omy0

I will try your “LDR TEST - 4 PWM component.fcfx” tomorrow. And let you know.

When I use a 3K3 resistor (in R25) between the PWM1 line and the mosfet the mosfet does not dim anymore.
I use “TEST PWM PIC16F1788 - 01 - LDR Treshold in Macro.fcfx”

Hi Martin, Thanks, I will wait for it. I have made it on a breadboard based on your “LDR Bright Control1.png”. I have used logic level NPN mosfets. This example shows 1 mosfet. When adding mosfet 3 it looks like the PWM1 pin can’t handle it anymore and PWM1 stops working.(The 0R resistor is just in ...

Hi Martin, Please, can you show me how to implement your program “LDR TEST - 02.fcfx” into my program? I have been trying for one and half day but maybe I don’t understand your program. Btw, to use PWM on all 8 outputs does not work. It stops by adding output 3. With 1 output it works great but in m...

Hi,

FYI.

The above error suddenly came back. After deleting the reg key Flkowcode8 FC starts again.

Hi Steve,

Thanks. It is still working without any crashes or Windows shutdown. I have opened FC8 many times now.

So it could be a registry problem. Because when I delete the FlowcodeV8 key it is still working after a reinstall. But this is up to you

Regards,

Frank

Hi, I have the same problem. FlowCode crashes and Windows shuts down. The crash from FlowCode comes randomly if I click something in FlowCode. This I have since I bought V8. Now I can’t even start FlowCode. The “start” logo is been seen and then it disappears and FlowCode won’t start anymore. I have...

Hi Martin, Your program works now on my hardware. The LEDs are dimming when I shade the LDR. Only the LEDs are flashing very fast. Where can I change this? This is not clear to me. PWM is new to me so I thought that it would be easy to dims the LEDS with a “central PWM Macro” I have made some progra...

medelec35 wrote:Hi Frank,

Does the brightness of LED vary depending on light falling on the LDR?

Yes, at daylight the LEDs must have a full brightness of 100%. When it gets evening to night the LEDs must dimming to 70% or 60%.

Hi Martin, Thanks for you input. But,… I don’t understand your program. Sorry. I have 8 LEDs connected to PORTC I have 8 Flash Patterns (8 Macros) I have a DIP Switch with 8 positions on PORTA with 10K Pull Down resistors This program work fine. The only thing that I want to have is an LDR which is ...

Thanks Martin,

But take your time, this evening I don't have time.

Hi Ben, Thanks for your input. But I think we misunderstand it. Attached you find a simple program from a bigger program. I have made two flashing Macro’s (Pattern 01 and 02) It would be nice to have an “LDR Macro” that every Pattern Macro will read. (or something like that) I hope this program make...

Hi all, It is long time ago that I have ask the above question. I couldn’t get to work on this by vary reasons. But now I have time and I can work on this. I have read the full answer from Docara and I have made two simple flowcharts. To make it more clear. I have 8 power LEDs which are flashing in ...

Hi Ben,

I wanted to test this rotary switch on a PCB. Unfortunately Seeed has send me some PCBs from a other person.

So. I’m sorry for this but I must wait one week to have my PCB’s.

Frank

WS2812B - Microchip or Atmega ? I need to control 300 WS2812B LEDs (5 meter) Before I start developing a driver board I need to know which chip I should use for this project. I have read that the younger Microchip devices such as the PIC16F1509 are fast enough to control 300 WS2812B LEDS. Or should ...

Hi Ben,

Thanks for this rotary switch component. I will test this in the weekend.

I will let you know.

Regards,

Frank

i Ben, Thanks for your answer. It would be great if you can make a component for this kind of rotary switches. They are very useful to use. In my current situation I make use of DIP switches but the problem in this is that you can make easily an error because you can have multiple ON possibilities. ...

Rotary Switch and Inputs. I need to make use of a rotary switch on a PIC16F1788 to select 8 inputs. I’m new to this kind of switches, so :( I think I will make use of this rotary switch: https://nl.farnell.com/1522030 (2 Pole) or https://nl.farnell.com/1522028 (4 Pole) I don’t know the difference to...

Hi chipfryer27,

Yes this was the problem. Again something learned

Many thanks for this quick answer.
