Embedded Template Library



) was first pushed to Github back in 2014, but I had been developing the
concepts behind the


for quite some time before that. I had found it a little annoying that every time I changed
employer I had to reinvent the code, based on the concepts I already knew.

In 2014 I had a couple of months between jobs, so I decided to put my knowledge into a library that could be shared
with other embedded coders. At the time, the functionality was fairly limited and I just worked on it one or two
evenings a week at the most. Now, over seven years later, it has a far greater range of functionality applicable to the
embedded developer, and a large number of users have downloaded the library for everything from personal
projects to international companies developing commercial products.

This has increased the workload tremendously, sometimes up to 30 hours a week. Unfortunately, this is not
compatible with holding down a job that pays the bills! When I have to find work, the


gets very little attention.

At the moment, I am funding time working on the


through my personal savings.

Please consider sponsoring the


and allow me to give you the support you and the hundreds of other users

Many thanks,
