hi so i use an esp 8266 to control the dmx dimmer of some lights via mqtt and nodered
The only problem i come across after a few minutes of use it resets at the begining mayebe 30' nad after every 10 or more minutes and send these errors :

After a few seconds i get following message:

Greetings everyone,
thank you all for your contributions to DMX.

I 'm playing with the espDMX example and i have some issues running the code on wemos D1 mini v2 and i have implemented the MAX485 topology on dmxA(Tx0), a status led and i connected a 7 channel RGB led par.

I modified the steps for an R-G-B-black:

1-Master Dimmer
2-Red
3-Green
4-Blue
5-strobo
6-macro1
7-macro2

//4 steps with 7 channels in each
byte dmxChase[][7] = { { 255, 0, 0, 0, 0, 0, 0},
                        { 255, 255, 0, 0, 0, 0, 0},
                        { 255, 0, 255, 0, 0, 0, 0},
                        { 255, 0, 0, 255, 0, 0, 0}
 
};
void loop() {
  for (int i = 0; i < 4; i++) {
    
    // Output channels 1 - 10 on dmxA
    dmxA.setChans(dmxChase[i], 7, 1);

    // 1 second between each step
    delay(1000);
  }
}

what i get as a result to the led par is:
at the very first loop is almost the sequence as i wrote BUT
after that, every time the status led is blinking, it's like it runs 5 steps.

Any ideas?
Thanks in advance

How can you overcome jitter? devices do not perceive the parcel DMX, although the analyzer is fine. This project proposed a jitter solution, I can not apply it to yours. https://github.com/robertoostenveld/arduino/tree/master/esp8266_artnet_dmx512

I'm just getting started with this and am stumbling thru getting the Arduino environment setup.

I cloned this library and when trying to compile the example sketch, I get the following errors:

Evening

thank you for sharing espDMX, I have been looking at the dmxChase example and I have that working within another project I am working on and it works perfectly, but my what I can seem to so if get a artnet values from channel one and then turn that into a DMX value to output.

Any help would be gratefully received.

Thank you in advanced

Tim

I need a way to customize the pin to output to a MAX485.

I hope you can help me on this.
