Resolved! STM32G0 DAC ADC TIM2

Using TIM2_TRGO to trigger DAC. That works.Now want same TIM2_TRGO also to trigger ADC.Is that possible ?Regards Juergen

center-aligned PWM timer with a secondary channel that has a delay (phase shifted)?

Is it possible to have a center (or centre in old english) aligned PWM timer wth a secondary channel that has a delay(phase shifted)? I have seen it done with the standard count up timer but I am struggling to achieve this in center aligned mode. I a...

mpu6050 returns zero, I2C stm32f103

I am working with MPU6050 and STM32f103VE as master. When I wake up the sensor and ask for information it returns 3 bytes of zeroes and the protocol stops working. I only send the communication Part of my code to be more specific:void I2C_interface(v...

Delay in microseconds for stm32l0 cortex m0+

I Wanted to generate the microsecond delay function, I have tried below functions but these are not working, It will be good if someone knows the delay function.static inline void delay_us( uint32_t micros){ micros *= (SystemCoreClock / 1000000) / ...

Resolved! Cannot connect to STM32H753I_EVAL2 board anymore

I know it sounds like a dumb question but I cannot connect anymore to my STM32H753I_EVAL2 (that I've been using extensively for months). I checked the driver in Windows Peripheral Manager. It is properly installed and it shows the same driver DLL as ...

STM32F412 I2S DMA pause resume does not work as expected

In our system the I2S is set up with DMA in full duplex mode (circular, no fifo). That works, we get all the halffull interrupts.Now, ideally, what we want is that some user input will reset the dma buffer pointer.I found that in order to do that we ...

when program started interrupt is called but its read only one character and repeatedly read same character.most time getting garbage value. RXNE Flag also set. my application is to handle data send by ATMEGA16 in while condition.program: voi...

Is Programmable voltage detector interrupt through EXTI_16 is available in STM32F427 ?

Can't seem to find more information on programming PVD and External interrupt 16 in STM32F427 series. Please share the sample code if available.

Are the STM32F301x4 and STM32F302x4 devices discontinued?

Hi everyone,This is a fairly straight forward question. The STM32F301x4 and STM32F302x4 are listed on DigiKey as a non-stock item but are still present on the website when searched. I was unable to find any reference manual for these parts as well. A...
