Using eInk display with LPC55S69 and OKdo E1 board

I have continued to explore my two hobbies (embedded systems, and Talking About The Weather) during these weeks of lock-down. I have finally got to the point that my Weather Station project can sit on the window shelf of my office, and show me the temperature, humidity and atmospheric pressure on the attached eInk display.

weather station project: it is warm, cloudy and low pressure outside

In this blog I’m going to focus on driving that display.

From C to C++: Converting Eclipse C Projects

Creating a new project with Eclipse for a microcontroller these days is fairly easy, and I have the choice if I want to start the project with C or C++:

Choice of C and C++ for a new project

Still the embedded microcontroller world is dominated by C and not C++. So while it is easy to start with a C++ project, most vendor provided example or tutorial project are C projects. So how can I transform such project to C++?

MCUXpresso SDK Tutorial – using I2C Driver on OKdo E1 board

In an earlier tutorial I introduced using I2C with the NXP LPC55S69 on OKdo E1 board to read a Bosch BME280 environmental sensor on a Mikroe Weather Click board. The MCUXpresso Clocks, Pins and Peripheral Config tools were used to get it running. It’s all for my Weather Station project that I’ve been working on during these months of lockdown. It is starting to take shape – as you can see from the photograph:

From the left: Mikroe Weather Click, OKdo E1, Mikroe eInk Click.

Now I really need to start reading and writing to the BME280 sensor, and that means using the I2C driver in the lpcxpresso55s69 SDK. And so this week I’ll provide a forensic examination of the most commonly-used I2C function call.

How to use Eclipse CDT Environment Variables in C/C++ Code

When using a logging framework it is useful to use the current file name or line number. The ANSI C/C++ standard defines the __LINE__ and __FILE_ preprocessor macros for this.

But what about the project name, if it is a release or debug build, the microcontroller used or other things like the operating system which was used to build the binary?

Target Chip Name

Target Chip Name

This (and even more) can be easily provided by Eclipse to the C/C++ application being built with CDT.
