    [SOLVED] Need dac simple modifiable example for stm32f429zg

    I made a mistake and did not make the "reset and run after download" check box active. My codes were working and needed to restart. Thank you.

    [SOLVED] Need dac simple modifiable example for stm32f429zg

    Hello, I have to test a board which is designed containing stm32f429zg core, I want a sumple example to configure and set value (whether dc or sine signal). I am very newbie here and Cube example or other sources didn't work properly. Also I couldn't find any part inside that codes to let me...

    [SOLVED] Creating a very sharp pulse generator

    It's a good suggestion. However 74hc14 is too large for me. I want to replace this circuit with a crystal oscillator so I do not have a large space. Is there any small package one?

    [SOLVED] Creating a very sharp pulse generator

    Thanks, is there any specific known circuit for that. What I want exactly is to have an oscillator with specific frequency, which an equivalent could be exist in form of oscillator pack.

    [SOLVED] Creating a very sharp pulse generator

    I meant fast slew rate. Not a specific v/us is considered.

    [SOLVED] Creating a very sharp pulse generator

    Hello everyone, I want to generate a clock with about 4 MHz frequency (should be adjustable) which is very clean and sharp. I can not access ready oscillators. I have test a crystal collpits circuit but it is not sharp enough. Any suggestions? Best Regards Ya Montazar

    Microblaze SDK problem

    First, create a new source of microblaze in the ise/vivado. Then you should specify the processor(s) and its peripherals in the XPS environment. After generating netlist you may export the design into SDK directly or closing XPS and export the design from ise/vivado. Using MBLAZE is so...

    How to create and code a 16-bit spi interface in Microblaze?

    Hi to all. I have created a spi module with 8 bit width data. Now I WANT TO change it to a 16-bit one. To do this,I have change its property in XPS and now I should change the codes. I use this function to transfer data. Xspi_Transfer (&mySPI,data,NULL,1) The spi definition is now 16 bit but...

    Microblaze migration to new device

    if you had read my question you would see that I have told about virtex 6 device so it couldn't be in vivado ;) . - - - Updated - - - The Problem has been solved, and that was missing the elf file. so I add it manually and then synthesize it again....

    Microblaze migration to new device

    the target device and previous one are compatible. but especially the MBLAZE does not work,yet. however it seems the rtl codes work with no problem. (regenerating IPs as I said means they just upgraded by software without any changes from me.)

    Microblaze migration to new device

    Hello all, I have had an about complex project using Microblaze and so, Implemented in a v6-130t and ٍnow the employer asked me to displace it to v6-240t. what I have done to do this migration is regenerateing all the componnets such as IPs for new device. the problem is that in new project I...
