    [ARM]Closed: Re: Enc28j60 with STM32F4

    You need to add 'Network Interface' to FreeRTOS TPC and add a ENC28J60 driver. I did that before and can give you my codes.

    But! F4 has it's own MAC which has a official FreeRTOS driver and...

    [ARM]Closed: Re: stm32 interfacing with enc28j60

    enc28j60 is just a phy. It has nothing to do with ethernet data.
    IP processing have to be done by sw.
  4. Closed: Re: STM32F3 + SPI Ethernet interface and Http server etc.

    I did that a year ago. STM32F103 + ENC28J60 over SPI.
    FreeRTOS + TCP. But you will have to provide the driver by yourself if it is not available.
  5. Closed: Re: Sine PWM calculated with pic, instead of using table

    The concept of using constant table in flash is to fully dedicate the processing to interrupts/perepherials. So, the main cycle will be free for other purpose.
    In your case you don't need mcu at...

    Closed: Re: Arm RTOS C++ newbie advice

    STM32 + FreeRTOS
    Using C++ will require to use dinamyc memory allocation. Don't use malloc, it is not thread safe. Redefine it with heap.4 or heap.5 functions from FreeRTOS.

  9. Closed: Re: STM32F103 (Blue Pill) can only get A0->A3 to work as outputs

    Yes, you have init code for PA0 PA1 PA2 PA3 only, not surprised why the rest is not working.
  10. Closed: Re: STM32F103 (Blue Pill) can only get A0->A3 to work as outputs

    I still don't see any initialization for gpio.
  11. Closed: Re: STM32F103 (Blue Pill) can only get A0->A3 to work as outputs

    You don't have to. F103 has bitbang access to gpio. But in theory yes, you should.
    If you wanna get a help about your issue, you need to provide full code.
    Weird, that I have to explain that.
  12. Closed: Re: STM32F103 (Blue Pill) can only get A0->A3 to work as outputs

    Did you enabled the RCC for portb?
    Did you initialized pins as output? Default is analog input.
    HAL_GPIO_WritePin may be a not a thread save function, also don't use static variables inside...

    I would suggest to stop for a while and think. There are totally mess in your head. May be we should start from beggining? What you want to achive?

    If you will mix up drain and source, all current will pass throuhg the internal diode and thus it can warm up also

    One advice before we will lost you for a years. Forget 'Sainsmart' and 'mega'. This words are unnesecessary. Exlude them from daily usage.

    Sorry, I can't provide any code. This driver has no hw dependency. It can work with any hw. But you need to provide interface functions. SSD1289 support spi, i2c and parallel 8 and 16 bit interfaces....

    LCD controller is SSD1289, touch ADS7843. For both of them there are a lot of code examples in internet.
    I can give you my lcd driver for SSD1289, but I don't think you gonna be happy having it :)

    I wrote my own sw i2c lib long time ago and using it in many projects. It is simple, you can do that easily.

    i2c on f103 is a pure pain. Even in commercial projects i'm using sw i2c implementation. Thanks god, it has bitbang
