How to combine two PWM pulses along with a delay in between?

I am using stm32756G eval board. I want to generate a pattern of two PWM pulse along with a delay. Example: A pulse of 1Khz + delay (milliseconds) + A pulse of 1KhzI am able to generate a PWM pulse of 1Khz.Is there any example for that in stm32cubef7...

Hi all, I am using a high speed ADC (AD9601) and I would like to know if STM32F429 could handle this high speed or i should use a FPGA in between. Thanks in advance.

This https://www.analog.com/media/en/technical-documentation/application-notes/AN-835.pdf helped me but I was not able to dig deep about STM32F429 regarding this.

How to program an STM32 ARM micro controller

Hi guys, I have a project where I need to use STM32 ARM processors I want to be able to program a bare chip of STM32's ARM Microcontrollers on my breadboard. I have a ST link V2 as the programmer. I would like to know what software (for free only)/ap...

i would like to know whether Serial NOR flash ISSI (IS25LP256D-JLLE) can be interfaced with STM32F437VI through SPI and we are using this flash for memory extension alone. Not for programming or code storage. Thank you in advance.

DMA to/from external SDRAM

Using the STM32F769 Disco, I've enable the external SDRAM using the FMC and can read/write that memory.I also have both SAI audio and microSD interfaces working with DMA, as long as the memory target/destination is internal SRAM. However, DMA transfe...

How can you get the time in milliseconds in reference to a particular timebase (e.g. epoch)?

I want the epoch time in milliseconds (or with a milliseconds field), but the main function that is suggested out there clock_gettime() ends up as an undefined reference. I have also tried functions like gettimeofday() but it always returns zero for ...

How do I properly configure the USART Receive for FIFO Interrupts on the STM32H753IX?

I am able to receive data on the USART1 peripheral on the stm32h753-eval board using the character match and RXNE Interrupts. When I configure USART1 peripheral for FIFO mode, I set RXFTCFG to 1/8th in CR3, I enable the FIFOEN in CR1 and the RXFFIE i...

SPI/DMA error on STM32F4

I'm trying to implement an SPI slave using DMA on a NUCLEO-F429ZI board. It basically works but when transactions from the master come too often (about 1ms) I start getting SPI overrun errors (i.e. HAL_SPI_ErrorCallback() is called). I would like to ...

HOW TO SAVE ADC RESULTS?

Hi everyone, I am new to the community and I am also not very expert on microcontrollers. I own a STM32F407G-DISC1. I was able to write the code for ADC (at least I think), but I don't know how to save the data on the memory. Can anyone tell me how t...
