Background
Level 1: Getting the source (from Git)
Level 2: Making system calls to flash an LED
This task outlines level 3 of the course, a little bit harder, building on levels 1 and 2. Based on feedback given at the meeting where level 2 was shown and comments on the videos this next instalment should:
- Continue to be single tasking/command line based
- Comprise more than 1 source file (as a means to introduce using a makefile, or needing to link 2 or more objects together, or the equivalent in the respective language, eg.
LIBRARY in BASIC)
- Comment on where to find background material in the PRMs or StrongHelp manuals (rather than just pulling magic numbers out of the air)
- Handle the error return from a
_swix call (or equivalent, eg. SYS in BASIC)
- Use file I/O (contrasting the language built ins like
fopen() or OPENIN with SWI OS_File and OS_Find)
A tutorial example which takes a sprite or JPEG, queries its dimensions, and prints them to the console. With a suitable framework this could be extended for other types by the avid reader like PNG or GIF, and take the general form
*ImageInfo <imagefile>
At level 2 we presented (in order of most number of views first)
- Assembler (gas syntax, ObjAsm optional)
- C (with the DDE, gcc optional)
- C++ (in CFront, g++ optional)
- Python
- BBC BASIC
- Lua
Don't be limited by these 6 though! All languages for which there is a RISC OS variant are up for grabs if volunteers have a particular area of interest they'd like to produce.
Definition of Done
Paolo has kindly offered to 'top & tail' any videos submitted.
The meeting to review this topic is 03-Jun-2023, so ideally material needs to be complete by 27-May-2023 to give time for editing.
This task would be complete once the new level 3 videos are edited and available on youtube for developers.
