Posted on June 30, 2016 at 16:20I have an SPI slave. The master may request data at a faster pace than I can handle in software, so I've set up DMA. I've prepared a buffer etc. Now after one transfer, I get an interrupt of the DMA having finished (i...
Posted on July 01, 2016 at 04:14I tried editing the simple DMA example in STM32Cube_FW_F7_V1.4.0\Projects\STM32F746ZG-Nucleo\Examples\DMA\DMA_FLASHToRAMI changed the DMA direction register so its memorytoperipheralinstead of memorytomemory. And I ch...
Posted on July 01, 2016 at 07:39Hello all,I use STM32F303VC and plant to use UART to receive data, but the receive size of data are different. Does anyone know how to implement it?Thanks
Posted on June 25, 2016 at 09:20Hello, 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 28, 2016 at 21:11I have a STM32F4 Discovery board. I have GDB connected to OpenOCD and when I run my program on GDB it executes perfectly. When I disconnect the board and program it via ST-Link nothing happens. I tried and older progr...
Posted on February 06, 2016 at 18:06 I am using STM32F407VGT-6 chips. I use the DMA2 Stream0 with the ADC1 to read analog values. On two of my Boards, the code is working fine and I am not having any problems. On a third Board I programm...

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 ...
