    [ARM]Closed: Re: emwin whitout external ram stm32f103

    It is possible. I have STM32F103VC which runs emWin on SD1289 320x240. But you need to understand that basically all cpu resources will be used for GUI.
    In your case you have a troubles with...

  4. Closed: Re: Real use of left and right alignment in ADC

    For 10 bit adc, if you need all 10 bits you are reading low and high value of conversion result using right alignment. If you need only 8 bits, you use left alignment and take only high value.

    [General]Closed: Re: Structure Copying Issue in Keil

    You have no understanding of pointers

    data_ID *dataID = (data_ID *)malloc(sizeof(data_ID ));// Allocate memory for struct data_ID
    After this txdata will still be a undefined pointer and have to...

    [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.

    [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.
  10. 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.
  11. 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...

    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.

  15. 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.
  16. Closed: Re: STM32F103 (Blue Pill) can only get A0->A3 to work as outputs

    I still don't see any initialization for gpio.
  17. 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.
  18. 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...
