I am not shure, but there must be a mistake in Example4-ArtnetOutput at line 33: I think there should be "WiFiUDP" instead of "WiFiUdp". Now Arduino IDE is compiling only with the error message: "pragma message "No hardware SPI pins defined. All SPI access will default to bitbanged output"" Now I hope, that I can send DMX messages from my Computer or the lightning-mixer to the ESP32 - that was the reason to buy ESP32 Thing Plus and ESP32 DMX to LED Shield. I will not buy a second pair only for running Example1 or Example2 !!!

how can i implement a function or a variable to show me when the cable is disconnect (or not presence)?

I have a problem, when compile a simple sketch that result a led blynking when receive dmx data, led not stay on, just blinking; i´ve tested in another ESP32, anothers shields, but result same error. Using DMX input mode:

include <SparkFunDMX.h>

SparkFunDMX dmx;

define LED 2

define TOTAL_CHANNELS 1

void setup() { pinMode (LED, OUTPUT); dmx.initRead(TOTAL_CHANNELS); digitalWrite(LED, HIGH); delay(1000 ); digitalWrite(LED, LOW);

}

void loop() { dmx.update(); int datadmx = dmx.read(1); if ( datadmx >= 100) { digitalWrite(LED, HIGH); } else { digitalWrite(LED, LOW); } }

tenting in arduino - Conceptinetics librarie work very well.

No other processes like > handle web page, configuration and other parallel tasks, only hard coded WiFi configuration
all other parameters like universe boundary limit , universe number is fixed ip address is based on DHCP(will be fixed in router using of ESP32's mac address) is fixed . So.... . what is maximum number of dmx universes i can handle with 1 ESP32 with fixed settings? signal strength of WiFi is >90%

hello, first sorry for bad english.

i´ve tried using EEPROM together to save dmx address, but when "commit" to save, ESP32 reset, and send me that message: Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory region accessed);

i think that EEPROM use core 1, maybe artnet too, but i dont know how to solve.

Hello, I'm using WS2813 LEDs with this in an effort to have a wifi controlled digitally addressable LED strip. 5v to 5v, clock to c0, data to d0, and GND to G. I was able to get the ESP32 with DMX shield configured and connected to wifi, however, it simply outputs a mess of random colors to the LED strip (and not to the correct number). I'm very familiar with Resolume and correctly outputting artnet data, but the input doesn't seem to be received by the LED strips correctly. Still flashes random colors even when Resolume isn't sending anything.

Hello,

I preface these questions with a warning that I am extremely new to this world of micro-controllers and arduino chips. I am a theatre technician building an LED illuminated prop.

Is there a version of this product without the XLR-3 Jacks? What are the physical dimensions of the board?

The physical limitations of the prop are rather specific.

We started this build with a Adafruit Circuit Playground Express, due to the many built-in sensors and the need for the LEDs to react to movement from the accelerometer. I now need hierarchical control of the board from a wireless DMX receiver.

If I follow my logic correctly the setup would look like this:

Lighting Control Board sending a DMX value change > Wireless DMX transmission > Wireless DMX receiver > SparkFun ESP32 DMX to LED Shield > Circuit Playground Express > Neopixels.

Am I missing a piece or over-complicating this? If you can provide some dimensions I will order a couple to begin testing. Any and all help or advice appreciated.

Thanks,

Christopher

Hi,

dmx.read(HUE_CHANNEL) is returning an erratic stream of values regardless of the fader position and regardless of the channel. I attempted to post a topic to the forums but got a 403 forbidden error.

I added Serial.println(dmx.read(HUE_CHANNEL)); in the Example 2 loop function, with no other changes. DMX data was sent to the shield from ENTTEC DMX MANAGER with ENTTEC DMX USB PRO. Tested Channel 1 on a moving head fixure, and it performed as expected.

Serial output was an erratic series of values between 0 and 255. A value would repeat a few times, and then another seemingly random value would replace it and repeat a few times, to be replaced by another. Values were not influenced by the fader position as far as I could tell.

How can I get the fader level for a channel from the DMX input instead of a random stream of numbers?

Thanks, Eric

Its not running for me. I got the follwing error: "# pragma message "No hardware SPI pins defined. All SPI access will default to bitbanged output"" When I try the example FastLED - Demoreel100, I get the same error. Simple Blink is working, also Adafruit DotStar - strandtest. I can't find any mistake, installed all new for a new user, but nothing changed.

It looks like the Artnet library has been updated, and the sample code for the artnet slave over wifi no longer works. Any chance of getting an updated example please?

I'm new to DMX. Trying to get this shield to connect to a series of DMX PAR lights I got online that had decent reviews.

The 3-pin XLR cables have a female and a male connector on each end. The DMX-IN port on each light takes a female cable connector. The DMX-OUT port from the Sparkfun board also takes a female connector. Is something backward or should I pick up a female-to-female XLR adapter?

I've tried all the possible male/female port configurations and run the code that changes brightness from 0-255 but nothing happens. This seems like it would be a pretty common configuration.

EDIT: got my hands on a 3-pin female-female adapter. So now the DMX-OUT from Sparkfun board goes into DMX-IN of the light. Still no go. The program sets all R/G/B and brightness channel values to 255. Nothing happens.

Any tips appreciated.

"Typically, the female XLR connector on the slave is the input while the male is the output."

Incorrect. DMX outputs use a female connector and inputs on a male. https://en.wikipedia.org/wiki/DMX512#Connectors
