A few months ago, I published post about DPA .NET Class. This article describes simple, but effective library used for DPA handling by MCU (UART interface). Published library is independent on the MCU family, but it was written for 32-bit ARM processors with Cortex-M3 core and GNU C compiler.
From OS v3.06D, upgrades can be done by the user oneself, using IQRF IDE v4.30 (menu Tools – Change IQRF OS Wizard) or higher. Downgrades (down to v3.06D or higher) are possible as well. Whole process is very simple and this short article shows you, how to do it.
This article describes simple wireless Dallas one-wire device ROM reader. It is intended as a base code for some more sophisticated access control system. We try some kind of access system in followings articles. Now, we are going to read 1-wire ROM code.
This post demonstrates, how to use functions startDelay() and isDelay(). It is a response for questions from visitors of this website. At beginning I am going to show you, how to use simple startDelay() and isDelay() functions combination for red LED blinking. Then we will do some simple but useful temperature measurement application.
