STM32F4xx - Cerberus Helper Classes


#1

Hi All,

I have converted the file: ‘stm32f4xx.h’ to C# as a helper class. Its too big to run in Application so portions may be used separately.

See Codeshare for full code: https://www.ghielectronics.com/community/codeshare/entry/919 <-- Updated…

Just a small snippet: as this is a huge file!!!

Very simple to use:


GPIO.GPIOA.MODER_Register.SetBits(3 << 8);

    
    /// <summary>

    /// </summary>

        private UInt32 _MODER = 0x00;
        private UInt32 _OTYPER = 0x04;
        private UInt32 _OSPEEDR = 0x08;
        private UInt32 _PUPDR = 0x0C;
        private UInt32 _IDR = 0x10;

        private UInt32 _BSRRH = 0x1A;
        private UInt32 _LCKR = 0x1C;

        // Alternate Function Number 
        private UInt32[] AFR = new UInt32[] { 0x12, 0x12, 0x22, 0x22, 0x22, 0, 0, 0x32, 0x32, 0x32, 0x32, 0x92, 0x92, 0x92 }; // AF1/2/3/9}

It is indeed huge :slight_smile: Consider splitting to smaller files — my Firefox dies trying to open that Codeshare entry!..


#3

Yeah I had similar problems… Mind you, 886Kb isn’t that much…

New codeshare link: https://www.ghielectronics.com/community/codeshare/entry/919

All the best

That’s good, sorry, thought it was a site issue and not so much a size issue.

Glad you can get to it now.

All the best

I have made some revisions to the Code and updated a few minor items.

See: https://www.ghielectronics.com/community/codeshare/entry/919

Changes:
[ul]I2c and USART completed Class Code.
Added GPIOC, D, E, F, G, H and I.[/ul]

I am in the process of using this file in my Windows application and sending the Address’s and bit procedures through serial interface so I will post application soon.

All the best
