Programming

In the past I have written on the advantages of minimal development environments (read: Makefiles and GCC, no IDE, minimal abstraction layers) for ARM processors. One of the advantages of working this way is easy integration with existing processes such as build systems, production line, testing, etc. Using this in a virtualized environment also allows one to make sure every developer uses the same tools, and that the tools are tested and qualified for the intended project with a ready made virtual image available for each developer. They can then add their favorite editor and user interface, but the underlying build environment is fixed for everyone and archived as such on a per-project basis. This means that if a customer comes back a year or two later and wants to make a change, all the tools are there as we left them ready to make the change. In this blog post I'll write down a possible scenario for a typical STM32 project, in this case using a NUCLEO-L152RE board as a target. It should be easy to adapt to other STM32 boards/chips, and in general other ARM microcontrollers as well.

The STM32 line of microcontrollers offer a bunch of features in a nice package at reasonable cost, something I like. What I don't like as much are the development libraries around it provided by ST. For this reason, most of the time I stick to writing code using the 'Cortex Microcontroller Software Interface Standard' (CMSIS) and the datasheet, and this works nicely but can be slow to develop. While it's still my personal favorite, I recently checked out the other options to see where things are going to do the prep work for some ports of older projects built using the 'Standard Peripherals Library' to newer processors such as the STM32L4.

For a while now I've been evaluating some 32-bit micro controllers for a future product. One of them was the STM32L15x series. There are some handy development boards available such as the Nucleo boards. Since we need to have the ability to program processors from Linux for our small production line, tool support is one of the checkboxes that need to be ticked.

For the STM32 series, flashing the microcontroller can be done through GDB, OpenOCD, and the STLink tool. One issue that arose however was the need to program the EEPROM available on the STM32L series. This requirement comes from need to generate and program different EEPROM content on a per board basis at the production line. Doing that requires a few tweaks that are documented below...

In the spirit of "never give up, never surrender", we're back with a Kickstarter project! Just like the previous one, it has to do with GPS and location, but this time we focus on a particular application: bike security and tracking. We're doing this project in partnership with Cycling Boom.

 From a recent LinkedIn thread (didn't correct spelling, but you get the idea):

Need suggestion for future career

Hello all, I'm looking for a new job, but now I'm really confused. My friends suggest me for iOS/Android development, 'cause that are the most popular and easy to get started. But for me, that's not cool, not challenging and not exciting at all. No offents. Most of them are SNS and incredible easy on programing. I was tired some hardware R&D company, didn't goes well, very little salary or named "R&D" in fact "Copy and Paste"(and some company just told me that "BEc not under consideration"). I love embedded C programming, but looks my country didn't (nobody interested in teach newbie), it's too hard to improve my skill without product R&D. Should I follow my firend's advice to became a framework based SDE, or other way out?

It is not just this one person, but plenty of other young people struggle with this, in a variety of different fields. I replied with a 5 step 'program' to the question, and it seems that others appreciated it as well. I'm reproducing it here just in case it disappears from LinkedIn...
