I have posted two articles about temperature loggers. But these loggers had one big lack. They had no decent GUI. So, I sat down and made one. And there is…
It is based on DPA Terminal published before. So it was not as difficult as it might seem.

DPA Terminal – Relay Board control
DPA Terminal
Two weeks ago, I published post about DPA .NET class. This class is useful for everyone, who would like to work on own PC application for communication with DPA coordinator. I used this class in my new tool for DPA application testing. This tool has name DPA Terminal. This software is published with full source codes. So, If you want, you can use it and change it against your needs.
DPA .NET Class
If you worked for a real application with IQRF modules with DPA, you’ve probably reached to the conclusion that for communication with PC is very convenient to use UART. Me too. I like UART for his simple handling and easy accessibility, unlike SPI (just PC has no native SPI port 🙂 ). This post describes simple classes for DPA ↔ HDLC conversion written in C#.
Wireless temperature data logger II
A month ago, we tested simple temperature logger with EEPROM storage. Today, we are going to do some improvements. We will use external EEPROM – EEEPROM for data storage (128×16 positions) and EEPROM as settings storage. In addition we will make a sampling period adjustable by DPA command.

External DAC – MCP4706
Two days ago, we tested Microchip MCP3021 ADC. Now we are going to test simple and very cheap Microchip DAC MCP4706. It would be useful especially with (DC)TR-52 modules. More inside… Continue reading
External ADC – MCP3021
I’ve used the AD converter several times in my articles, but you could be in situation, when you need more ADCs, or you have not enough IO ports. In these situations an external AD converter is suitable choice. I tested MCP3021, cheap and simple ADC worked on I2C bus. More inside… Continue reading
PCA9634 (LED driver) driven by DPA
Some months ago, I wrote article about PCA9634 LED driver. I made a Breakout Board for this IC and made IQRF application for this board. Now it is time to try make it better – with DPA.
IQRF Relay Board II – upgrade to DPA
One of my first post on this site was IQRF Relay Board. I made a simple board with shift register and eight relays. All was controlled by IQRF P2P application. Now it is time to make some upgrade, upgrade to DPA and make real IQMESH device. How is it simple? You will see inside…
