I’m in the final stage of finishing a electrical vehicle (EV) charger controller, which optimizes battery loading using the available PV system: use as much as possible the solar energy and not the grid.
For this last blog in the series Investigating ARM Cortex® M33 core I decided to explore the expansion features of the LPC55S69-EVK. This board has three expansion ports (PMOD, Arduino Duo, Mikroe click) and I picked the Mikroe expansion port. Why? Only because I had good experience with these boards with the Hexiwear project.
And because I have been doing some work this month with AWS IOT I wanted to get my LPC55S69-EVK onto my office WiFi network for the Christmas holidays. I know that the MCUXpresso SDK for lpcxpresso55s69 version 2.6.3 has a built-in WiFi example named qca_demo, and so that is what I am investigating today.
That WiFi example supports three WiFi shield boards, and I picked the Mikroe WiFi 10 click board. It’s part number MIKROE-3432 and available from all of the usual catalogue distributors.
I’m a fan of all kind of weather stations. When Daniel Eichhorn twittered about his new version using an E-Paper display module, I immediately preordered one. I decided to build a station with a custom enclosure, so here is my version of a 3D printed version, featuring magnets so it can be attached to the fridge:
I’m convinced that this ‘Internet of Things’ thing-thing is not real. Pure marketing and buz words without any added value, right? The IoT hype is so bizar: it must be originated by aliens which have taken over the brains of all the Pointy-haired Bosses of the world? There is no useful application or use case out there!
But wait! There *is* actually good use case, at least for the geeks of this world. We all love clocks as we want to know the time, and we all love the weather forecast so we can plan accordingly. At least I usually do :-).
