The problem:
If several people are working on the same account (Linux) then it creates problems to work with remote git repos. You just do not want to store your ssh credentials in the same account.

Solution:
Set up a bare git repo that works as a "remote repo" where all users are pulling and pushing to this bare repo and not to the real remote git server. Benefits:
do not need any credentials to push to the bare repo
do not need to set up new Linux account (maybe that would have been better)
On you own local machine you set up a new remote, for example rpipoc01. Then you can push the git repo to the bare repo. After that you can clone from the bare repo to the repo where you intend to perform the work. When finished, push to the bare repo. In order to push the updates to the server, you pull the updates from bare repo to your own machine (specify when pulling the bare repo, for example rpipoc01). The push (or pull request) to the server.

git clone /home/pi/bare_repos/sss-poc-imx-web-packager.git

Importera data från lastkajen 5.10 (https://lastkajen.trafikverket.se/) till QGIS 3.4.
Från lastkajen laddade jag ner filen för Lund, Lunds kommun GeoDb_GeoDatabas__2975.zip. Innehåller en mdb fil. Import av databasfilen till QGIS skedde mha instruktion från https://www.northrivergeographic.com/qgis-accessing-personal-geodatabase. Det kanske finns ett bättre sätt? I vilket fall så får man möjlighet att välja olika lager som finns i mdb-filen. Ett av dessa är C-Cykelled. I QGIS kan man bla, efter import, undersöka olika egenskaper hos befintliga objekt (olika cykelsträckor i det här fallet).

Simple gpio is based on xmos an00155 for xCORE-200 eXplorerKIT.
Here, I'm applying the code on MCA.

Observe that instead of using the led matrix on MCA, I'm using 
a single bit port normally used for OPT_RX (which I monitor 
with an oscilloscope).

I have built with unchanged Makefile Target, i.e. xCORE-200 Explorer Kit
