The code below is just to show that it is possible to connect and is far from optimized. The top unit will still send data if you press any of it’s buttons. It is not necessary if you only want to receive data. SPI via SPI (Serial Peripheral Interface) pins SCLK, MOSI.

You will have to use the PDF mentioned and send the appropriate bytes to the CDJ. ICSP (In Circuit Serial Programming) 6-Pin Cable coverted to Arduino Pro Micro headers. Select 'Arduino Micro from the Tools > Board menu. Programming The Micro can be programmed with the Arduino software (download). The Micro appears as a generic keyboard and mouse, and can be programmed to control these input devices using the Keyboard and Mouse classes. Now when you have prepared your CDJ and Arduino with the code below your CDJ will give an error “E-8709” this is because the Arduino is not sending any information back to the CDJ. For SPI communication, use the SPI library. If we want to know if the PLAY button is pushed we will have to look at byte 14 bit 0. When you scroll to page 4, you will see that the data from the CDJ is sent in 27 bytes. You will need to look this up for your specific Arduino, not all Arduino’s use the same pins.īefore we look at the code, be sure to look at “Reverse_Engineering_Pioneer_CDJ-1000_serial_protocol.pdf” you downloaded from GitHub with the link at the beginning of this post. if you use a 3.3 volt Arduino you will need a logic level shifter.ĭon’t forget to disconnect your CDJ 1000 mainboard to prevent errors! Solder 5 wires to your front panel (see pictures) and connect these wires to your Arduino. This is because the CDJ is also working at 5 volt. 1.) The RESET pin on the Pro Micro is -not- in the same location as the Pro Mini (not sure why this was done, but it is what it is).
#Spi arduino pro micro install#
The first google hit will give you VID en PID for DDJ-SX2 "PIONEER DDJ-SX2 2IN2OUT" vid="0x08E4" pid="0x01A2" And don’t forget to install the MIDI USB lIbrary.Īlso make sure your Arduino is operating at 5 volt. You will have to do this in your Arduino IDE “boards.txt”. If you want to connect you Arduino to Rekordbox use the same trick I used in my project with the STM32 Discovery. If you want to use the Arduino for midi make sure it has an Atmel 32u4 like the Arduino Leonardo or Pro Micro.

Full OTA software updatability (HTTP + ArduinoOTA), password protectable.
While I consider this an easy project, things could go wrong and you can damage your electronics! So do this project at your own risk! WS2811, SK6812) LEDs or also SPI based chipsets like the WS2801 and APA102.
The link to GitHub contains all information on CDJ 1000 mk3 SPI. Again this wouldn’t have been possible to do without the research of Andrei. This post is all about reading the signal from the CDJ with the Arduino. As mentioned before in my “ cdj-1000-mk3-for-rekordbox” post I first connected the CDJ to Arduino.
