Posted on June 24, 2016 at 09:24Hello, I'm looking for information about the circuits to add to a STM32F7 Nucleo board to build an operational SPDIF output. I tried to find the information in the STM32 reference document, but could not find the inf...
Posted on June 30, 2016 at 21:57I plan to use the STM32F40x TIM1 CH1 (PA8) to produce a varying PWM signal. The base frequency is set, say 1 MHz. I need to use DMA to change the PWM duty cycle on every iteration. I know this can be done by aiming...
Posted on June 30, 2016 at 16:43Hello,I'm navigating trough STM32L052 documents but could not find any information on specific IRQ numbers besides the ''stm32l052xx.h'' from Cube L0. Also, connections between peripherals, EXTI and the interrupt cont...
Posted on January 02, 2012 at 04:06I am using STM32F103 MPU.I set the board as SPI Slave and uses DMA to receive and send data.Most of time Command comes from Master and Slave responses.So I made code to wait for receiving Command from Master. Once ...
Posted on June 28, 2016 at 17:39I wish to transfer a large array of data to 8 output pins that are all on the same port. E.g. a 500 element 8bit array where each bit of each element represents the pin status.So 500 independent transfers to the port ...
Posted on June 30, 2016 at 12:38hi i wanna connect stm32f407discovery board to stm32f429 via uart communication. how can I calculate the closest baud rate to 5Mbps for these 2 board? I use following cod and it work but I want to be sure about minimu...
Posted on June 30, 2016 at 13:14i want to make low cost oscilloscope i want the maximum speed can i work with external adc using stm32f4 what is best dcmi or fsmc and can change dcmi or fsmc clock out frequency through mcu running. https://www...
Posted on June 29, 2016 at 15:11Hi there, I'm implementing a bootloader. And have created an application vector table that is different to the bootloader vector table Boot Vectors at 0x08000000 App Vectors at 0x08010400 volatile const void (*vector...
Posted on June 30, 2016 at 11:53Hi,i am designing one sensor motion board using STM32411CC for which we wanted to connect four 6 axis inertial sensors to STM32F411CC controller( 48 pin package) using SPI bus and the selected controller having only t...
Posted on June 20, 2016 at 16:12I'm trying to generate a single pulse wave, having about 20 toggle transitions. I've created such a generator, and the thing that I haven't solved yet is how to stop it. The aim is to have the pulse wave start after p...
