Dipswitch programmable start address

A power supply (up to 4 can be connected), a USB-DMX dongle (or E1.31 to DMX bridge) and a computer (or Raspberry Pi or BeagleBone Black running FPP) is what is needed to control Christmas lights.

165mm x 93mm

Replacement mosfets are available here.

An updated/alternative to DMX36 that uses dipswitches rather than software to set the start address. All other specifications are the same.

Firmware updates

Firmware update can be loaded through the ICSP header with a Pickit3 (or PicKit2) pic programmer. Pin 1 of the ICSP header is marked on the pcb and is shown to the left. Ensure the pin 1 (the arrow) of the header is aligned with pin 1 of the programmer. Via MPLAB MPLAB must be installed. It is available from microchip.com
Plug your PicKit 3 into a spare USB port, then start MPLAB X IDE (or version 8.84 or whatever). Once it has loaded, click Configure > Select Device to bring up the device selection window. From the device drop-down list, select PIC16F884 and click OK.
A dialog saying “New firmware must be downloaded for PicKit 3 to work with the part selected.” may pop up at this stage. If it does, click OK and wait for MPLAB to download the programming firmware to the Pickit 3. You will see some activity in the PicKit 3 tab of the output window for up to a minute or so. When MPLAB is ready you will see “PicKit 3 Connected” and possibly an error stating “PK3Err0045: You must connect to a target device to use Pickit 3”. This is not a problem and just a warning that the PicKit 3 cannot “see” the chip yet.
Then, click File > Import and browse to the DMX36Mk2 1.0 HEXFILE.hex file (latest version at time of writing) and click Open. The last line of the build tab of the output window should read “Loaded C:…DMX36Mk2****.HEX.”
Now, connect the PicKit 3 the 6 pin ICSP header next to the micro. Make sure the arrows on the Pickit 3 and the 6 pin header are aligned. Then power up the DMX36Mk2. The PicKit 3 tab of the output window should now read “Target Detected”.
Click Programmer > Program to initiate the ICSP operation. The PicKit 3 tab of the output window will show “Programming…”, then “Programming/Verify complete” once it is done. Disconnect the PicKit 3. The PicKit 3 tab of the output window will show “Target Removed”.
Via “Programmer To Go” feature of PicKit3
If a PicKit 3 has been preprogrammed with firmware then all is required is that the DMX36Mk2 board is powered up. Plug the PicKit3 onto the header as shown above. Power the PicKit3 by plugging it into any usb socket. The power led on PicKit will light, the status led will be green and the blue active led will be flashing. Press the pushbutton. The status led will turn red, the active led will turn solid red. When then Status led turns green again and the blue Active led starts flashing the firmware has been updated.
Via “PicKit 3Programmer” software
The Pickit 3 programmer software can be downloaded at http://ww1.microchip.com/downloads/en/DeviceDoc/PICkit%203%200.3.3.0%20Setup%20A.zip .
Extract and run in. Select PIC16F884 as the Device. Select File>Import Hex> and browse to the DMX36Mk2 1.0 HEXFILE.hex file (latest version at time of writing) . Plug in the PicKit 3. If the DMX36Mk2 is powered then click on write and it will update the firmware. If the board isn’t powered then click on the “On” button in the “Target Power” section. The power and mode light on DMX36Mk2 should then power up. Click on “Write”.
