GPIO_Digital_Output

[ART_ME]

Hello.
Need advice for a beginner.
In the examples MikroBasic have UART, which is an expression of GPIO_Digital_Output (@GPIOD_BASE, _GPIO_PINMASK_ALL) 'digitalni output
GPIOD_ODR = 0
Where can I find the rules for this expression, if it is in the same example in C is not?

Hi ART_ME,

Welcome to the MikroE forum.
You can take a look in GPIO_Librray in the Help menu in the compiler.

You can use similar in mikroC for ARM:

Code: Select all

GPIO_Digital_Output (&GPIOD_BASE, _GPIO_PINMASK_ALL);  //digital output
GPIOD_ODR = 0;

Also, each example in mikroBasic is available in mikroC too, you can find appropriate examples
in installation folder, but also when you click on Open Examples Folder... icon in the compiler.

Best regards,
Lana

Hi ART_ME,
You can take a look in in the Help menu in the compiler.

Dear Lana,

My mistake was that I was looking for GPIO library in Library Manager, where it does not exist.

Thanks

And again the question of the beginner.

There are instructions:

sub procedure GPIO_Clk_Enable (dim port as ^ longword)

and it is an example of the expression:

GPIO_Clk_Enable (@GPIO_PORTB)

What is "@", and where it came from?
"GPIO_PORTB" - is a variable or it is described in some rules?

Hi,

Please take a look at the image in attachment (which is taken from the Help menu),
for detailed explanation what is the use of operator @.

GPIO_PORTB is GPIO PORTB register, you can find definitions of appropriate MCU
when you open Defs file (Ctrl + Alt + D), but for information like detail explanation of MCU registers
you need to search the MCUs datasheet which you are using.

Best regards,
Lana

Hi lana.arsic,

Pointer is not basic. Pointer is C. Therefore, I could not guess what this character should look at the statements.

Then I see if GPIO_PORTB is dim, then I have to use pointer.

Thanks.

Hi,

The mikroBasic compiler supports pointer type, it may be derived from other languages, but it is widely used in our codes.
If you have any problems or questions, we will gladly help.

Thank you, filip.
Earlier on your site had a separate section on libraries. And now I can not find it, there is only HELP in the compiler.
Is it possible to return this section of the site, and even better to link to pdf for ftp?
Use the description lib directly in the compiler is not always comfortable.

Hi,

Thank you for your suggestion, I have forwarded it to our developers.

Meanwhile, here is a link with libraries:

https://download.mikroe.com/documents/c ... raries.htm

You can open Help file separately, from installation folder,
but just in case I'm sending it in attachment.

Best regards,
Lana

Lana, thank you very much for your wonderful response.
