The lack of vendor-agnostic hardware abstraction layer (drivers) in FreeRTOS was my main reason to use ChibiOS for my projects. Although, libopencm3 has progressed nicely, so FreeRTOS + libopencm3 could now be a decent alternative to ChibiO

Two things from my experience: 1) Read the fine print when it comes to processor manufacturers telling how much time something takes. Although PRU subsystem is deterministic and __most__ instructions take 5ns, there are quite a few cases wh

I'm fond of STM32 Discovery/Nucleo devboards. They have all the required debugger/programmer hardware on board, can be used as debuggers/programmers for standalone STM32 MCUs and are very well priced (you can get one for

Second this as I tried platformio for STM32 recently. I was expecting hiccups due to arch usually having newer versions of libraries but everything worked out nicely.

Well, of course it's easier to have a single off-the-shelf solution which solves N things than have to cook up the same solution using separate independent pieces of software. But I would argue it's easier to debug and modify each

I'm using arch on T430s and T440p. wicd didn't play well with wifi card/driver on T430s- no wifi after resume. It works fine with NetworkManager though (or maybe driver was updated in the meantime). I'd recommend a Tx30(

I recently got T440p with 1920x1080 screen and I quite like it (at least, compared to my T430s with 1600x900 screen). I'm inclined to believe that colors look dim because it's a matte panel- don't Mac's come with glossy

Compatiblity with existing libraries and example code for other Arduinos is the key here. I find it surprising too, but there are people who do not really want to know all the low-level details but get the result quickly :)

It's interesting how newer technologies allow us to notice these kinds of bugs. I am unable to read speed with 1 km/h resolution on my car which doesn't have digital speed readout.

I'd make that statement the other way around- open source firmware supports hundreds of routers. It doesn't look like the openwrt folks and others get much help from the router manufacturers.

CSS/HTML frameworks like these are very well suited for web interfaces running on embedded microcontrollers, where storage comes at premium and design requirements are moderate. Looking forward to actually trying this in near future!

Well, you better not choose Riga (capital of Latvia) then. According to my back-of the napkin calculations, an 80 000 EUR investment will pay itself back in 10 to 15 years.

Aren't the linked peristaltic pumps a little bit too slow for this purpose? It would take 3 minutes to fill 300ml of soft drink on top of 200ml vodka.
