Dear ST Community,The MCU type is: STM32F407VGT6I try to write GPIOx->ODR register with DMA2. The trigger signal is TIM1 update event. I set the timer period frequency is 9Mhz and i measure 4.429Mhz on GPIO pin. Why?here is my code:#include "stm32f4x...
Hi everyone,I want to have a section in FLASH that will act as an EEPROM with some initial values defined at compile time. I have defined the section in the linker script (the last page of the FLASH) and I can see it in the .map file correctly.Howeve...
Hi,Turning Voltage regulator into low-power mode (LPR) in Stop mode possible only for Category 1 devices as stated in RefMan (6.4.1 p158), but referring on datasheet for L051 family (that's category 3) that's however possible (3.1 p14 & 3.4.3 p21). S...
Posted on January 10, 2017 at 05:44Hi,I am developing application on STM32F0 MCU to interface with external android device (host) via virtual com port.I plan to use USB CDC class on STM32 USB library so that host device. STM32 VCP driver only availa...
Posted on January 27, 2012 at 20:58 There is bug in USB Host library that causes to wrongbehavior if the attached device has more that one interface. EP properties for interface 0 is overriding by the values for next interfaces. There is also a ...
I want to interface HMI with STM32F1 MCU using UART to RS232 converter but i can not found any MODBUS library for STM32 mcu.
Hello,STM32G0 provides additional device pins by using onlt one VCC/VDD pin pair. Is there any deeper explanation how this is achieved?
Hi,I am working on STM32F042.I have setup the BxCAN peripheral into loop-back silent mode, and it works fine. I can transfer and receive every single frame I am transmitting and no error conditions are detected.However, I have noticed that when I wan...
Posted on November 27, 2017 at 14:20Hi everyone,I'm trying to clear my head around interrupts with an STM32l0x3. I'm not using HAL functions, rather I'm trying to understand the logic behind all this.This becomes a little bit messier since the NVIC ...
