Typo in RM - DMA_SxNTR
In the ADC chapter, DMA_SxNTR register is mentioned. There's no such register, it's DMA_SxNDTR.This goes across many RMs - I've checked several 'F4 and 'F7 (using simple text search) and all of them contained it.JW

Resolved! STM32F446, QuadSPI Bank1 CS signal
Hi folks,currently I am working on an communication with a sensor via QuadSpi using the STM32F446 controller. The QuadSpi Bank1 was chosen, but unfortunately the hardware designer did not connect the Chip Select signal (CS) to the pin that correspon...
[rtems] when enable idle interrupt uart receive nothing
HI, ALL !i am debugging the stm32F407 uart ON RTEMS, found that the idle interrupt will effect the RXhave cleared the idle flag by pragma but now i can not receive uart data, i don't know what's the erroruint32_t *USART2_SR = (uint32_t *)0x40004400;u...
TIM2 interrupt becoming de-activated
Hi all,I have an STM151 system (our own PCB) running FreeRTOS. As recommended, I leave TIM6 for the FreeRTOS timer,. and am using TIM2 to provide a source for the HAL_Tick timebase.In the BeforeSleepTasks (ie when all RTOS tasks are idle and the CPU...
SysTick
Hi guys, I am trying software timers without using interruptSysTick->CTRL = 0x5; SysTick->LOAD = 0xFFFFFF;SysTick->VAL = 0; when start the program, what will happen with SysTick->VAL = 0; it is value start with 0xFFFFFF or 0?
Resolved! STM32F7 DMA Circular Mode Not Circulating
I'm using an STM32F769 for a project. I'm trying to continuously stream ADC samples to a buffer. I can fill the buffer without issue, but the DMA never recirculates back to the beginning. I don't get any DMA errors, and the ADC is still running (I...
Can anyone please suggest me a resource from which I can learn STM32F4VE from scratch?
I recently bought a STM32F4VE board. I have experience in 8051. Im unable to learn program the STM board on Keil. Its completely different compared to 8051. Im completely confused.

Resolved! Clock source for USART3/4 IN STM32G070
STM32G070. It is said there are 4 USARTS in the datasheet. For USART3/4, there is no place talking about the clock source for them. Would you please tell us what's the clock source for the USART3/4?
What is the Reference input current flowing into VREF+ pin of STM32H753BIT6 ?
It will be in micro Amps only right...Will be helpful if you let us know the exact value..
