Delay generator based on STM32F429

HelloI am trying to delay a 1Hz digital signal.I would like to generate a delay varying from a few microseconds to 10 ms.I tried to use ETR, TI1_ED and PWM input but I didn't manage to found out how to do.Does anyone has an idea on how to proceed?Bes...

stm32F103 ibis model error!

Error :Messages for model XXXX：Vmeas_(rising/falling) is set,It is necessary for delay neasurements. satisfy Vinh >= Vinl.

What happens when I read/write byte at arbitrary address shown as reserved in memory map (or write to flash memory address)?

I am exploring the memory space of my STM32F051 using a very simple hex monitor that communicates through a serial port. I can (attempt to) read/write a byte at any arbitrary address in the 32-bit address space. Within the SRAM area (starting at 0x20...

UART4 and UART5 Receive DMA interrupt on STM32F767ZI

I am using receive DMA to mange reception of data on UART4 and UART5.The setting of both UARTs is identical. UAERT4_RX is using DMA1 Stream 2UAERT5_RX is using DMA1 Stream 0I’m using halt transmit, transmit completed callbacks and idle interrupt to m...

float argument inside function stopping the infinite loop. screen sorts and file are given below. Edit: mcu I'm using is stm32f411re .

if I give argument like above picture infinity loop stops workingbut if I give the number num inside function the instead of giving argument then its working fine.If I give int instead of double as the datatype of argument then also it's working.Plea...

During the test, we found that the reference voltage of DAC channel 1 for STM32L4P5is 3V，while the VREFBUF for channel 2 is 2.048V，they are not identical，and the VREFBUF->CSR value is 2.

Are there any DISCO or EVAL boards for STMH7 MPUs that offer access to an unused I2C bus for external peripherals?

I might be missing a trick here, but it seems that most (if not all) DISCO / EVAL boards expose the same I2C bus externally that is used to communicate with onboard peripherals.This makes perfect sense with DISCO boards as they are small / low cost. ...
