Hello,I have three interrupts,One from EXTI4, which has NVIC_IRQChannelPreemptionPriority = 0One from EXTI9_5 which has NVIC_IRQChannelPreemptionPriority = 1One from TIM4 which has NVIC_IRQChannelPreemptionPriority = 2For testing purposes, EXTI4 and ...
Hello, what's the difference between the "Normal" and "Circular" modes of the STM32 DMA ?As far as I understand - "Circular" will write to the first address, auto increment the address to the next one until the last address is reached and then return...
Hyperbus RAMs requires 12 pins for implementation and offer decent speed. I have already 16 spare pins for the data/address and 10 other pins for fsmc handshaking. have any one tested this option before? is this easily implemented using HAL library o...
Hi,I'm using the flash in a dual-bank mode. I would like to have a common (shared) sector between the 2 banks for storing configuration data. This becomes somewhat tricky when addresses are shifting according to the active bank. How should I go about...
I tried this tutorial - https://www.carminenoviello.com/2015/06/04/stm32-applications-eclipse-gcc-stcube/ - Build STM32 applications with Eclipse, GCC and STM32Cube. In the last,it was said:we have to declare which MCU we are using defining a global ...
Hi All,As is the topic. Maybe someone else is stuck with the same problem?I wasted the last few days trying to find why my code is giving wrong (to low) temperature readings but it looks like a device limitation. I try to isolate the test case but in...
Hi, I am using STM32F407 for my PMSM vector control project. And i need to determine the current position of motor for vector control. So I use TIM3 Encoder MODE (x4) and ı have 360 PPR (pulse per revolution) encoder. I set the ARR value 1439 (4*36...
Hi there!Here i'm with another question about UART. I know i have a tree mode for receive data from uart 1) Polling 2) Interrupt3) DMAi know the difference , but i'm soo confiuse about :Example : I work with interrupt where i put this declaration HA...
*How to save varibales or array of data in Internal memory on STM32F042G6*Can i get some example to understand this thing more clear.Thanks in advance.
