Creating delay using __asm__("nop")
How to measure the time from __asm__("nop") on STM32F730 using 216 MHz clock? I did try to check it using osciloscope without success. The time is bigger than 1/216 MHz.

Resolved! Looking for examples & how-to for stm32l051 i2c non blocking (i.e. interrupt) slave and master receive and transmit
Hello - I have been working with the l051 for 2+ years now on a product, using i2c-1 as slave to outside world and i2c-2 as master for local board downstream devices. while my interrupt-driven code "works," I continue to have bugs filed about both ma...
Sampling sound and sending it using RF, sending takes to much time
Hello, I am having a problem. I am using STM32F411CE and NRF24L01 module. I try to sample sound using ADC and then I send it using RF to another uC. I sample a simple sine wave at 48kHz with 16 bit resolution using IT. I send 32 bytes at one time usi...
Resolved! STM32G473 configure ADC in 16-bit mode
I need to configure STM32G473 ADC in 16-bit mode, Currently i configured it in 12 - bit mode it works fine but as per my application i need 16-bit resolution. As datasheet indicates it is possible to configure 16-bit mode by oversampling, but is ther...

Porting STM32F070 to STM32F446 issue with user data in option bytes
Hello, we are currently porting some code from STM32F070 to STM32F446. In the original code, we used to use a generic byte from the option bytes to keep some flags between two resets, without using one page of the onboard flash memory, using somethin...
Resolved! Controlling servo with potentiometer
I want to control servo movement with potentiometer. I'm using ADC and getting the pot value. But i don't know how to control the pwm with this value. What should i use?Thanks in advance.

Can stalled IRQs be interrupted by IRQ in RAM?
Hi,i'm dealing with the window watchdog.as my program erases a sector in flash i created a watchdog irq handler in RAM which retriggers the watchdog wen the sector is erased.my Watchdog irq has the highest priority. all other irqs have lower priorit...
