STM32 MCUs Products

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...

AN2606 pointing to RM0433 for STM32G43/7

Hello,AN2606 Rev 37 on page 321 writes:For more information regarding the STM32G431xx/441xx option bytes configuration, refer tohe STM32G4 reference manual (RM0433).RM0433 is the STM32H7 reference manual.

What should be the output value of ADC if input is not connected to dedicated pin? I am getting some values (230).

Hello, As I am working on analog inputs I require ADC. STM32F334 Nucleo board has 12-bit ADC (2) with 21 channels, I am using ADC1 Channel 1.After programming without applying any input to the pin (PA0) I am getting some values through USART2.Can any...
