Please Fix the ESP portion of this Lib .

[9ghost9]

I have added Change to the ISR ability and corrected what others have already suggested .

It is frustrating to purchase RobotDyn products only to have the firmware not function .

Here is the fixed Lib completed that will remove ESP flashing frustration and also enable reasonable AC LED control .

https://drive.google.com/file/d/13wZMFQneHm8znYDxutUyMGcZuyUESraV/view?usp=sharing

RBDmcuESP8266.cpp

line: 9 int rise_fall_change = true; // added change
line: 61 attachInterrupt(inPin, isr_ext,CHANGE); // set to CHANGE and works with incans or leds.

Note; From my testing and experience with the Robotdyn AC module , by adding a parallel load to Led fixtures the top end percentage is not clipped at 80% but works correctly through to 100%

Thank you

THANK YOU again! Works great on an esp8266, and doesn't need RobotDyn's library. 😁

Any chance you have one that works for ESP32? This (esp8266) version requires "ets_sys.h which isn't found for ESP32. I found an ESP32 timer library (hal_timer e.g. https://desire.giesecke.tk/index.php/2018/04/22/using-the-hw-timers-of-the-esp32/) but haven't had luck in using it for dimmer timing.

[9ghost9]

I had not considered AC dimming with the Esp32 but I will take a look at it when I have some free time.
I have found the Wemos mini pro with external antenna to be excellent for this task combined with the RobotDyn Wemos shield.
RobotDyn customer service is very poor in regards to their shield and is why I dumped their .lib for the hw_timer.

So ,some good news , I went ahead and built an AC dimmer that is controllable with any Arduino board or ESP module . . It does not use isr's but rather uses analogWrite and in the case of ESP32 LedcWrite for direct PWM control .

A very simple circuit to build as DIY !
Will probably need to go via PM from here if you need any more advice .

[unaipuelles]

Hi,

Anyone knows if can be used with the board of Arduino Uno Wifi Rev2 that has the chip Atmega4809. I try to compile the library for this board and I can't. I also searched for other dimming modules and I can't find anything for this board.

Thank you!

PD: This message has nothing in common with this issue but I don't know where to ask this because the maintainers of this repo don't respond anymore.

[homonto]

hi there, is there any progress with making this library working on ESP32?
thx

@9ghost9 , sadly I can't see a way to PM you in here. were you able to get this to work on an ESP32 by any chance? I just bought their 16A/600V dimmer and very disappointed that I can't get it to work on my 'ESP32 Dev C' unit & that RobotDyn don't offer any working software or help!

Hi Alan
Yes I have AC dimming via ESP32 , but not with these Robo-modules.

I built this circuit -> https://www.youtube.com/watch?v=XdCvJ1wZ0bA

This works perfectly with LedcWrite. PWM and a frequency of 1k - 5 k .

[Alan-Somebody]

Thank you very much @9ghost9 for replying and for the link. I will take a look.

[9ghost9]

There are a few cautions with this circuit .
The load line is constant /always live and L & N need to be wired correctly or short circuit will occur .

[9ghost9]

hi there, is there any progress with making this library working on ESP32? thx

Have you tried this link ?
https://github.com/RobotDynOfficial/Lib-RBD-Dimmer-for-ESP32/tree/master/RBDdimmerESP32

[Alan-Somebody]

Hi @9ghost9 . I did try the link yes. The code compiles when I tell the Arduino IDE that I am using an Arduino Uno, but the code fails when I tell it I am using the ESP32.

[9ghost9]

You need to install the RBDdimmerESP32 lib and install in your Arduino/library.

https://github.com/RobotDynOfficial/Lib-RBD-Dimmer-for-ESP32

I just tried and it compiles fine for Esp32 .
