Faster implementation of HAL_DAC_Start_DMA() to retrigger a single DMA transfer to DAC

I have configured a DAC to use DMA in single mode. I have created HAL_DAC_ConvCpltCallbackCh1(). In this function, I reenable the DMA process using HAL_DAC_Start_DMA(...), which appears to be really slow. How can I make this faster. I don't want to ...

What are the causes CAN macrocell remains into Sleep state?

Hi,I have a strange behavior on the bxCAN macrocells of a STM32F437 MCU and I'm here to askif someone has encountered the same situation.In my application I start programming one CAN module (say CAN1) to get some data sentfrom the other connected CAN...

Error/omission in RM0090: missing CC4NP bit definition

The CC4NP bit in the TIMx_CCER register should be listed in the reference manual in the section "17.4.9 TIM1 and TIM8 capture/compare enable register (TIMx_CCER)". Currently, only the CC1NP, CC2NP, and CC3NP bits are listed. The sections for the othe...

I am designing an PCB with an STM32H743 and IS42S16100H 1Mx16 SDRAM. I have two issues wiring up the SDRAM as detailed below.

The SDRAM has twelve address inputs A0-A11, where A11 is the bank select. In STM32CubeMX FMC section should I configure the SDRAM controller for 12 bit address and connect FMC_A0-A11 of the STM32H7 to the DRAM or configure for 11 bits and connect FMC...

STM32F2 Emulated UART

I have implemented an emulated UART on STM32F2 using the sample program from STM32F4. The UART TX data output is correct. Until a HAL_Delay(100) is add. When added delay, the UART TX output appears corrupted as shown below. Why is the HAL_Delay affec...

I am new to STM 32 MCU, it might be a basic issue I might be facing but couldn't find any solution in the documentations as well. When I am trying to connect STM 32 Nucleo and an IKS01A2 expansion board using a Unicleo GUI I am facing some problem

When I am trying to login to Unicleo GUI I am able connect to the communication port but the firmware description, version, expansion board name and library version in the login screen is showing unknown as I result , i suppose, am not being able to ...

I am working on H743. I have trouble getting ADC3 to work in continuous DMA transfer mode. I have ADC1 working fine but ADC3 wont work. Is there something wrong in my config?

After doing debugging i have found that the error code is set by DMA config function :HAL_StatusTypeDef HAL_DMA_Start_IT(DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength) { . . . . . else { /* Process...

Exiting STOP mode

Hi,I am a new coder using the STM32L100RC discovery board. As such, my problem is quite simple I believe; I cannot exit Stop mode using an external trigger on the WakeUp Pin PA0. The code works as fallow: the LED on the PC9 pin light up, I enter STOP...

Have anyone noticed a problem with the STM32L4 Wakeup Timer wakeup from standby with temperatures < -10°C?

The Wakeup works fine with temperatures above. At a unit based limit the wakeup does not accure (only watchdog as fallback). RTC remains running.Any ideas?
