Hy, I want to connect the RS485 receiver, and transmitter with Arduino to control the SM16512P LED strip. Can anyone tell me how to do that?
Google rs485
Google led strips arduino
Have a go with the first and get it working
Have a go with the second and get it working
Combine the two
Post specific questions and code in code tags if you are having problems with your attempts and your own research has not been fruitful
When i googled that i found that these are DMX ledstrip, with which you can set the address using an 'address writer', never dealt with them before, but as for standard DMX you can transmit it with an arduino, and all you would need is the RS485 transmitter since every chip on the ledstrip has a receiver. Makuna neopixelbus has recently included a DMX output for esp8266 MCU's , otherwise there are reliable methods of sending DMX for AVR's
Ok, thanks. But I think that the library does not support SM16512P
The library supports standard DMX output as in WS2821 on an ESP8266.
The SM16512P responds to standard DMX, but i can not find any information on how to set the address on them. No datasheet available, if you contact your vendor for a datasheet, then i can help.
As for using an AVR (Nano Uno Mega etc. I would use conceptinetics.h as a dmx library, which will work just fine, but will not be specifically meant for addressing LED's, so you will have to make the interface for that yourself.
