Velleman K8000 - [K8000 Standalone Usage] - [K8000 RC5 receiver]

K8000 RC5 receiver

One of my first K8000 applications for my FEZ board was an RC-5 receiver. This is a receiver which can decode signals that are sent from a Philips compatible remote control. In other words: You can control your K8000 with a standard remote control. All you need is an IR receiver that is connected an analog (An2) input of your FEZ.

GHI Electronics - the manufacturer of the FEZ - offers an addon for this: 'E-Block 38 kHz infrared receiver'. Using this E-block the easiest way since you can simply connect it to the FEZ with a JST3AA cable. If you prefer building your own IR-receiver you will need to get a receiver module 'TSOP4838'. This is a little integrated circuit with 3 pins: +VCC, GND and OUTPUT. You can power it with your FEZ and connect its output to the An2 input on the FEZ.

Sample Application

I have created a little sample application to show you the possibilities of combining a K8000 with a remote control. The sample allows the use of the following buttons:

The image below shows you developent setup. Here the FEZ is connected with the K8000 through the SCL/SDA and GND lines. The Ir E-block is connected to the Di2 analog input of the FEZ. The K8000 controls a Velleman K8000 dimmer that is connected to the 8-bit D/A output DA01 of the K8000.
