This post describes simple IQRF-USB interface. This device is based on FT230X device, which is USB to UART converter. So you can use gateway for example as coordinator of IQMESH network. Additional you can assemble STM32F100C4T6B MCU and write your own control application.
This post brings updated files for IQRF defined language syntax highlight and auto-completion for Notepad++ text editor. DPA syntax highlight and auto-completion for DPA 2.13 has been added. There are not only functions highlight, but variables, constants and structures has been added too. Notepad++ 6.6.6 and newer is required. You can use same installation procedure as in previous post.
A week ago, I posted some news about DPA Terminal. I promised, that I will add control capability for all main constructions from this site. A few days ago, I added Relay Board control capability. I had to change source code of Relay Board, but I think, the result is worth to it. Let’s see inside.
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.
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#.
This post describes simple RFID reader with wireless transmission to the PC. There is used Wiegand26 protocol for communication between TR-52DA and IQRF reader. This construction would be useful for installations on places, where you are not allowed to use additional cabling.
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.
Two months ago, I published post about Small Relay Box II. There was full design of small DCTR-driven Relay box. A week ago, I assembled the first piece of PCB and I discovered two bugs (one HW – wrong NC a NO contact description on silkscreen layer and one SW – wrong relay pin mapping).
