I’m using the RS-485 field bus in many of my projects: it is very reliable and robust, and easy to implement. And with ModBus there is standardized protocol used in building automation or industrial control applications. For example I’m using the protocol to communicate between battery systems and an EV Charger.
In this article I show you with an example, how the NXP LPC55S69 can be used with RS-485.
Continue readingI want to share with you a little embedded trick that I use to improve the reliability of my code. And in addition to improving reliability, the technique can be used to schedule any event to occur ‘sometime in the future’. It uses the MicroTick (UTICK) timer found on the NXP LPC55S69 microcontroller, and could be applied to any device with a simple timer.
The MicroTick timer is an elegant, thing of beauty. But there is not a driver example built into the lpcxpresso55s69 SDK, and I believe that the timer is not widely used. That means we need a tutorial!
