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

[Piranha]

Indeed there is one: https://www.amazon.co.uk/PCs-Dummies-Dan-Gookin/dp/1119041775/

Also try to accomplish this: https://www.youtube.com/watch?v=2eiUjfPiF5A

Thanks (for the second link). This talks about dev boards which I am not using. I have the STM32 already in my own board as mentioned earlier.

[Piranha]

Oh, you poor one. One of course has to be a genius to see the "Devices" tab besides the "Boards" tab.

Tried Blinky example but got error msg:

Error: Flash Download failed - Could not load file 'C:\Users\Admin\Documents\MDK\MDK\Boards\ST\STM32G474E-EVAL\Blinky\Objects\Blinky.axf'

And is the file actually there? Any other failures in the connection/download process

I'd build these things off an C:\KEIL directory

Does the project build and complete?

Does the ST-LINK find a connected STM32 device? Inspect Options -> Debug -> Debug Settings

Do the ST-LINK Utilities find the STM32 / Board?

Thanks. How to run the simulator?

[KDIAS.2340]

I decided to try the simulator instead but got stuck. I am in microvision and loaded the project blinky but could not see the simulate button. The video shows him opening MDK and then you get a list of examples and you copy the one you want and then simulate appears automatically in the abstract file. I don't think you have to do this every time you simulate but then how else can you simulate?

[KDIAS.2340]

At last, d'loaded Blinky via STLINK. When I ran it, the LED on STLINK started FLASHING red and green. So I assume my d'load to STM32G4 works OK. Now, I have to program the 3 motors for forward and reverse motion. Is there any code out there that can do it?

Thanks

[Tesla DeLorean]

You've got a custom board, with random motors. No one here was involved in your design. I'm not sure this stuff is the trivial exercise you think it is.

If you want examples, perhaps look at ST provided board/motor combinations related to the STM32G4, and apply what you learn there to your specific case.

You should engage with ST Motor FAE's, perhaps they can suggest seminars or motor hack-fest type events, or suggest contractors for motor applications.

[Piranha]

You mean a universal code for universal unknown drivers? How about learning how your motor drivers work and turning them on?

[KDIAS.2340]

I was trying to understand the C code for Blinky but with limited success, may be need a refresher on C. Any suggestions welcome

> may be need a refresher on C. Any suggestions welcome

Would recommend to look at courses and articles of Jacob Beningo.

I like his style of explaining things.

And then, more tools and TDD:

Thanks, but looking for something quick; ordering and getting a book - 2 weeks? with this virus. Having trouble with this line:

tid_thrBUT = osThreadNew (thrBUT, NULL, NULL);

[Pavel A.]

This virus time gives ideal chance to read a book.

Maybe he has some electronic format - pdf or doc ...

> Having trouble with this line:

 tid_thrBUT = osThreadNew (thrBUT, NULL, NULL);

This is a function call. osThreadNew is the function name. To the right of it are 3 parameters. To the left hand of it is the returned value.

Thanks. What do the 3 parameters signify
