Posted on September 22, 2015 at 20:35Hello,I'm having a strange problem that's been holding me up for the past few days. I've been trying to configure the FMC to work with a Cypress CY7C1051DV33 SRAM on a PCB that I developed. In fact, the configu...
Posted on September 19, 2015 at 11:29Hello! I have a simple program. It has software IRQ to enter Stop mode on return from ISR, and RTC IRQ to wake up and leave Stop mode. RTC IRQ toggles the red LED. On return from Stop mode (return from SW IRQ) th...
Posted on September 22, 2015 at 20:52Hi everyone.I am developing a robotic application and I need some advice.I need to drive two BLDC motors (these drive the wheels of the robot) and also to interface with a parallel camera.I understand that with S...
Posted on September 22, 2015 at 16:27Hi,I am writing a small piece of demo code that is located at 0x08040000 that we call when our boot loader has completed execution. I have looked at the NVIC and everything looks clean when we exit the boot load...
Posted on September 18, 2015 at 19:24Hi ST, When configuring the FatFS in Platform settings, I can configure the pin for card detect function. When using this config, following code in generated: uint8_t BSP_SD_IsDetected(void) { __IO uint8_t sta...
Posted on September 22, 2015 at 17:47Hi, Im using an STM32F071RB. I configured USART to receive data in DMA. I often get reception stuck but I cant understand why. I had a look at the registers: USART1->CR3 looses DMAR bit (0x00001040 becomes 0x00...
Posted on September 21, 2015 at 20:16Hey,I know that I can include a opt.s assembly instruction file in a keil project to set the read/write protection bits etc to level 1. I was just wondering, if I need to wipe such a device, how can I reset the o...
Posted on January 03, 2015 at 11:04HelloI'm using stemwin library for stm32f429 discovery. I just try to create simple project like - ''Hello world''. And my program hangs in GUI_init, namely in _DMA_Fill in line:while (DMA2D->CR & DMA2D_CR_START) {...
Posted on September 21, 2015 at 18:53I have an issue that seems to be related to some fundamental lack of understanding about GPIO behavior that I can't figure out. The most clear symptom I have identified is this:I'm working with an STM32F405RGT6 ...
