100 years ago I wrote a data logging programme for DOS which ran on a
Sharp pocket PC. It was written in C and assembler. I now have a need
for this programme and would like to revive it for use with the
Raspberry Pi.
I haven't done anything like this for some time and would like some
advice on current techniques to get the job done as soon as possible.
The first thing is a suitable IDE. I have had some experience with
Eclipse but it may be a bit heavyweight for quick results. However if
extra effort pays off in the end it might be worth it.
I will also need a lightweight graphics library. The original plotted
data on the display which was done with functions like
drawline(x1,y1,x2,y2) and writechar(x,y,char) etc. That sort of level.
Having said that, the Pi has a lot more capability and I could use an
existing display package.
The data came from various sources, some serial and some small devices
which were connected to the parallel port. The smallest timing period
was 1 second and I used the timer interrupt to initiate the read
commands because there was a lot of processing going on, updating the
display and also the logger had a modem attached so that data could be
collected remotely. Is this the way to go with linux or is there a
better/easier technique.
Originally I just recorded the data sequentially in a file but I was
wondering if there was any advantage in using something like sqllite.
I would be grateful to hear for any advice.
Thanks
Roger
