STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I didn't see PA11 and PA12 in this kit
After reading the section about Flash in RM0433 I am till a bit in doubt of the sequence of events during flash programming.This is important because I need to know that certain write operations are complete (such that the update is reflected even if...
Hello,we had trouble with a batch of STM32F103CBT7 processors. I have read a lot about counterfeit CPU's. I had the Error 18 in CubeIDE and 5 out of 1000 IC's did not work as our stock ones (STM32F103CBT6). The UID of one of the chips is UID0= 0x0047...
Hi,In my code Program counter struck in Default hander routine. .section .text.Default_Handler,"ax",%progbitsDefault_Handler:Infinite_Loop: b Infinite_Loop .size Default_Handler, .-Default_Handler how to know what is the cause for this and how to o...
hi we want to debug from the external memory interface. Actually my code size is more than internal RAM memory, so we want use external memory jtag debugging. is this external memory debugging possible? if possible what is procedure ?
I have an idle interrupt, on usart2 handle;void USART2_IRQHandler(void) { /* USER CODE BEGIN USART2_IRQn 0 */ /* UART IDLE Interrupt */ if(__HAL_UART_GET_FLAG(&huart2, UART_FLAG_IDLE) == SET) { __HAL_UART_CLEAR_IDLEFLAG(&hu...
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...
