    Closed: Re: Suggestions of RTOS for STM32F429

    If you are using the STM32Cube then it has FreeRTOS already in it with some documentation.

  2. [PIC]Closed: Re: PIC16F1934 Timer0 and some other stuff

    Just to be clear: with the IF bit set (and also the IE bit set of course) the ISR will be called. You *should* clear the IF flag in the ISR to make sure that the next time it is set by the hardware,...
  3. Closed: Re: CAN communication between two nodes (PIC18F458 and MCP2551 ) hardware

    How are you testing that you are not getting any output?
    You say you are using a PIC development board - which one?
    Can you toggle the RB3 (CAN output) pin with your own bit of code?
    Where did you...

    Closed: Re: STM32L475 IoT with bluetooth module

    What experience do you have with programming any microcontroller, let alone the STM32L family of devices?
    I suspect that you are jumping in at the deep end without knowing the basics which is a path...

    Closed: Re: Pic32 qei interrupts

    Which compiler are you using?
    If it is XC32, then the User Guide will show you very clearly how to write an ISR.
    If it is some other compiler then I a pretty certain that its User Guide (or similar...
  6. [SOLVED]Closed: Re: Generating Sine Wave Through External DAC (STM32)

    This part of your code makes no sense - it means that you are always using 's[0]' to hold the value. Therefore why create an array when all you need is a single variable.
    I suspect that you are...

    Closed: Re: How to do 8-bit wide write with FMC?

    You really need to show us your code so that we can see what you have done.
    I can only guess but you probably have not configured the FMC correctly.
    Can you explain what you mean by a 74-bit bus?...
  8. Closed: Re: Connect 32 serial lines to uC (eg. ESP32) over I2C or SPI?

    It sounds like you are capturing the console logs for these devices. Is the console port the *only* place the text is stored?
    At least on many servers there are log files that you can access,...
  9. Closed: Re: Problem with PIC16F877A, infinite loop output voltage 0.6V

    Looking at the last 3 instructions in your post #9 (before the 'return' that is) and without knowing what happens in the 'enable' and 'writestar' functions, it seems to me that you always call the...
  10. Closed: Re: Getting trigger signal for 555 timer from elevator button.

    Reading your first post worries me a little in that you seem to be just trying various values of your components to see what happens.
    What you need to do is to learn how to read the data sheets of...

    Closed: Re: 12 Bit ADC with interfacing SPI in STM32

    I think you are getting a number of concepts mixed up here.

    1) Sampling rate: You will need a timer to reliably trigger the ADC sampling at a regular interval.
    The way to tell the ADC to start...

    Closed: Re: 12 Bit ADC with interfacing SPI in STM32

    You are still treating the SPI module like a UART (which can do independent transmits and receives).
    Not tested but try something like:


    spidata[0]=0x00; // Set everything up before you...

    Closed: Re: 12 Bit ADC with interfacing SPI in STM32

    Have you changed the setup of the SPI module from the one shown in your first post?
    Basically, the SPI module should NOT be generating the clock all of the time unless you are in 'Receive Only' mode...

    [ARM]Closed: Re: STM32F429I-DISCO help

    I suggest that you start with something specific in mind to have the MCU actually do.
    Typically the first think is to 'blink a LED' - in order to get that working you need to have the development...

    Closed: Re: SD card - pull-ups required?

    I'm not so sure that this is a good idea as SD cards have a limited write/erase cycle life. Depending on how you intend to use the SD card, this could mean that the whole device needs to be replaced...
  17. Closed: Re: ADC simultaneous sampling of 4 channels

    Feel free to select any other ADC (and possibly any other MCU) that meets your requirements.
    Susan
  18. Closed: Re: ADC simultaneous sampling of 4 channels

    Check out the Family Reference Manual (FRM) ADC section for that device. The FRM documents often provide greater detail (and code examples) about how to use the modules than the data sheet. However...

    All that 'tutorial' does is now how to set up the SPI interface on an MSP430! That is not the same MCU you are using.

    Have a look at the demo code on the Microchip site. While that is written for the PIC families of devices, they are in C and the communication between the MCU and the ENC28J60 is via an SPI interface...

    Don't forget that the ENC27J60 provides just the bottom layers of the IP stack. You still need to provide the upper layers where things such as web pages, HTML code etc. are defined.

    General comment: if you use a simulator then you have just added another layer of potential bugs to your project.

    Also, if you are starting off a new project, then why use that MCU - there are more modern, powerful and cheaper devices available.

  25. Closed: Re: Proteus Error, No Source Line at PC Address

    Glad you have solved it, but that error message (or one very like it) can also occur when an error is detected within library code where only the object library has been linked in. Such library code...
