stm32g4 adc & dma &timer

I have stm32g441 Chip. ADC1 used in external trigger  mode and triggered by Time1Channel4 (OC4REF),But when T1Ch1- T1Ch3 worked in Center-aligned mode,T1CH4 has not Worked,ADC1 DMA interrupt occured,and occured in cycle.

STM32H7~How to allocate arrays to a certain location

I tried adding this to the linker file/* used by the startup to initialize data */ _sidata_RAM_D3 = LOADADDR(.data_RAM_D3); /* Initialized data sections goes into RAM_D3, load LMA copy after code */ .data_RAM_D3 :  {  . = ALIGN(4);  _sdata_RAM_D3 = ....

Can STM32G030Kx (LQFP32 package) high speed external clock signal (HSE) be generated from external crystal resonator, or it can be generated from external clock generator ONLY?

In STM32G030x6/x8 datasheet (DS12991 Rev 3, Table 12 on page 31) I see only input pin for external HSE clock source (LQFP32, pin 2 - PC14 - OSC_IN), but don't see OSC_OUT pin of HSE OSC.

STM32L4R5 PWM : Bare metal code| I am writing some basic PWM drivers using the TIM16 and TIM17. While initializing the TIMer register I came to a register TIMx_CCER. Can someone help me withOutput control bits for complementary OCx and OCxN channels.

Using HSEM of STM32H7 ( sharing data )

Hi, I am working in project in which I use an STM32H745, So am trying to share data between the two CPUs.first I create structure in the two CPU like this :I used the same memory addressstruct shared_data { uint8_t drdyM4; float32_t data_to_M7[6][1...

How to reset STM32 when a hardfault is triggered?

Is there a way to programmatically reset my STM32 program back to the beginning like when pressing the Hardware Reset Button ? I would like to reset my program when a random hard-fault has occurred, if possible, i'd also like to store to flash the da...

uart3 can't receive entire data

Hi All​I used UART3 of STM32F429 to receive data(larger than 10K). If the baudrate is 230400，the RX can receive entire file; But If the baudrate was 460800 or 921600，I can't get the entire file(143111 of 143316 bytes). Anyone can help?Regards,
