Posted on June 23, 2017 at 16:05Hello,I use the CPU STM32F765.I want to use DMA2 to transfer ADC-results into memory.This works fine if I use DTCM-Memory for the destination (128kbyte from 0x20000000 to 0x2001ffff)If I use SRAM1, DMA seems to work...
Posted on June 21, 2017 at 10:43Hi. I have not so much experience with bootloaders.I need to store in flash 2 firmwares (without to replace the ST original bootloader).My idea is: at startup time, if a particular signal is low the first firmware has...
Posted on June 26, 2017 at 08:53I asked this quiestion yesterday and for some reason I do not see it in the forum ans also did not got any email about it.I want to Set/Reset 6 GPIO pins belong to the same port using HAL what I am doing now is callin...
Posted on August 31, 2016 at 14:16Hi,Using the CubeF7 USB Host examples ok with default provided linker script (using SW4STM32 SystemWorks IDE).Yet, when moving the .bss & COMMON section out of the DTCM RAM region into the SRAM1 RAM region, example ...
Posted on June 24, 2017 at 02:22 Hello, I think variation of this question has been asked a couple of time, but i'm trying to understand why what I am writing is not working. Because I want to get some experience with the HAL librairies I go...
Posted on June 25, 2017 at 22:38Hi,I have been working on this for 2 days trying to figure out why my application just stops. After looking at posts on this forum, and other places, and reading the STM32F4 reference manual, I see no problems with my...
Posted on June 20, 2017 at 10:34I write since I have a problem using HRTIM with the Nucleo F334R8 development board.The firmware is developed using System Workbench for STM32, using the STM32 HAL libraries (and code Snippet for HRTIM). The MCU clock...
Posted on June 26, 2017 at 03:46Hello.CubeMX 4.21 + STM32Cube_FW_F1_V1.4.0. SPI DMA (SPI1_TX) not working on F103 series. Tested on f103c8t6 and f103rbt6. Result - MCU dont want working. SPI without DMA - all good.For example:uint8_t data = 0xDE;HAL...
Posted on June 24, 2017 at 12:51 I need to vary the frequency and duty cycle of a pwm using stm32f Inside the 'pulse finished' pwm callback i've tried the following code HAL_GPIO_WritePin(LED5_PORT, LED5_PIN, GPIO_PIN_RESET); //tentative 1 //T...
Posted on June 25, 2017 at 18:46Hi,I'm working on the STM32F769I-Eval board and trying to get frames from the ov7740 using the DCMI and DMA (stream 2 channel 1). my problem is as so: the ov7740 is in VGA format (640 x 480). when I'm trying to use th...
