Multiple Universes on a ESP32 Dev #156

simplo · 2024-06-09T18:17:14Z

Hi all, I'm trying to handle 2 RS485 on the same ESP32 Dev using port1 and port2 but as soon as the dmx_driver_install(dmxPort2, &config, personalities, personality_count); is executed the system crashes.
Would it be possible to handle different (even more than 2) RS485 just uninstalling the driver and reinstalling it with different pins and same UART port at each loop?

Can you share your setup ?

Hi, it seems to work in this way but the system freezes randomly. :(

#include <Arduino.h>
#include <esp_dmx.h>

int enablePin1 = 21;

int transmitPin2 = 17;
int enablePin2 = 2;

dmx_port_t dmxPort = 1;

// Buffer per i dati DMX
byte data[DMX_PACKET_SIZE];

// Intervallo di aggiornamento
unsigned long lastUpdate = millis();

void setup() {
Serial.begin(115200);
configureDMX(transmitPin1, enablePin1); // Configura il driver DMX per la prima volta con il primo set di pin
}

void loop() {
unsigned long now = millis();
if (now - lastUpdate >= 100) {
// Aggiorna ogni byte nel pacchetto DMX
for (int i = 1; i < DMX_PACKET_SIZE; i++) {
data[i]++;
}

    // Invia i dati al primo set di pin
    configureDMX(transmitPin1, enablePin1);
    dmx_write(dmxPort, data, DMX_PACKET_SIZE);

    dmx_wait_sent(dmxPort, DMX_TIMEOUT_TICK);

    // Log dei cambiamenti al monitor seriale
    Serial.printf("Sending DMX 0x%02X\n", data[1]);
    lastUpdate = now;
}

}

void configureDMX(int transmitPin, int enablePin) {
// Disinstalla il driver attuale prima di cambiarne la configurazione

dmx_set_pin(dmxPort, transmitPin, -1, enablePin);
}

I found that after some second I get this error:

Sorry, this is the last code version I have, the error is the same I posted before.

NEW UPDATE:

I'm using this code now, it works (I mean it doesn't crashes) but it seems to send same data to both the pins gorups:

You have a single dmxPort, you should have one by uarts, init both in your setup, then use dmx_write and use each dmxport as first variable of it.

Check this : #52

simplo · 2024-06-10T09:59:45Z

I know, but if I use uarts I can't use the serial for communicating with other systems.
What I'm trying to do is to use a single dmxPort and change pins each time, so I can use N universes.
Do you think it is possible?

cgiles · 2024-06-10T20:55:30Z

I don't know, but you should try to use dmx_driver_delete(dmxPort); then reinit your dmx driver and assign your pins. Maybe it can work.

simplo · 2024-06-11T10:39:55Z

Thanks for your reply, I tried but the system crashed often id I use the delete.
Now I'm trying another solution using a multiplxer to switch the transmission on different RS485 via hardware.
I think it could be an interesting solution for many people id it works.
Now the issue is speed.
If send two full data packets in the same loop cycle it slows down to 30/35fps (exactly the half of the FPS sending 1 packet).
Is it an intrinsic limit on the send command or there is some timing to fit DMX needs that we can speed up?
Thank you again for your kindness and patience.

cgiles · 2024-06-11T13:20:30Z

Is it an intrinsic limit on the send command or there is some timing to fit DMX needs that we can speed up?

I think it is a limit. As you need to wait it is fully sent, you will always divide the fps for 1 universe, by the numbers of universe you send.

You could check others libraries, see if they allow what you want to do.

Hi all, I'm trying to handle 2 RS485 on the same ESP32 Dev using port1 and port2 but as soon as the dmx_driver_install(dmxPort2, &config, personalities, personality_count); is executed the system crashes. Would it be possible to handle different (even more than 2) RS485 just uninstalling the driver and reinstalling it with different pins and same UART port at each loop?

See #150 there is a problem with using uart2

riwalker · 2024-06-11T22:24:30Z

I use UART2 with this code, and #150 <#150> is the fix Since I changed this init, I no longer have any issues with UART2 From: Ben Suffolk ***@***.***> Sent: Tuesday, June 11, 2024 6:15 PM To: someweisguy/esp_dmx ***@***.***> Cc: Subscribed ***@***.***> Subject: Re: [someweisguy/esp_dmx] Multiple Universes on a ESP32 Dev (Issue #156) Hi all, I'm trying to handle 2 RS485 on the same ESP32 Dev using port1 and port2 but as soon as the dmx_driver_install(dmxPort2, &config, personalities, personality_count); is executed the system crashes.

You may try pulling the latest commit on release/v4.1 to see if this issue is resolved! :)
