Not able to start. I d'loaded MDK529.exe , it is an icon on my desktop. I click on it hoping to run it but it gets me to another screen asking me to install. Is there a clear and comprehensive single set of instructions that actually work?

[KDIAS.2340]

Most of the links lead to nowhere i.e. 404 error

[KDIAS.2340]

I tried the book by Kerighan & Ritchie' it gave the foll ex.:

lower = 0;      /*  lower limit of temperature table * /

    upper = 300;    /*  upper limit * /

    step = 20;      /*  step size * /

Based on this the Blinky code should follow i.e. lower = thrBUT, upper = NULL, step = NULL but this does not make sense!

Any thoughts?

Trying to use Keil for compiling my C program. As a start, I tried compiling the Blinky.c program done by Keil - no luck, although I didn't change anything, got 114 errors, tried another ex, same. So, something I am missing (as always!)

> What do the 3 parameters signify

Are you incapable of even using Google?

But before even touching RTOS, you should learn the basics.

One can refresh only knowledge he already knows. In your case you must learn the C and MCUs. Probably the best tutorial to start with is this one:
