ya, you can give me your design details and requirement

Good evening everyone ! i need help , I'm developing a project with an STM32 microcontroller and need precise timing control. What timer and PWM features does the STM32 offer, and how can they be configured for accurate timekeeping and signal generation????

Which STM32 are you using? There are lots

Bunch of timers on this one.

There's more info about the timers on pages 33-36 here: https://www.mouser.com/datasheet/2/389/stm32f413cg-1851205.pdf

Unfortunately, the "best way" to configure the features is going to depend on your application and system design. This SKU supports both internal clock references and up to 18 timers with different resolutions that can be used to generate your pulses.

If signal generation is your target, the precision depends on what frequency of signal you desire. You can do you using DAC and this example shows reliably generating 26kHz signal https://github.com/angst7/stm32_functgen

Also, there are chips like https://www.analog.com/en/products/ad9833.html that can do upto 12.5MHz arbitrary signal generation controlled over I2C

Umesh Lokhande•2/26/24, 4:03 PM

The default Tx/Rx uses

UART0

UART0

which is mapped on GPIO1 (TX0) and GPIO3 (RX0)

Hi everyone , any suggestion about reliable third-party libraries or frameworks for building web servers on ESP8266 or ESP32? What aspects should be taken for web-based applications on ESP platforms?

Hey guys, with a lot of imposter syndrome kicking in; Seeing that I'm a total beginner in embedded system

. And what you guys post here is just wow! and way ahead of my current level. But I will not cry

John Eric•2/26/24, 8:56 PM

I'm a programmer and I have a really big passion in engineering; So I thought... What if I combine programming and engineering - that was when I found out embedded system.
In embedded system, I have created a spider with an Arduino(Just learnt about that few months ago).

Camila_99$$•2/26/24, 10:37 PM

Two years ago, I remember my teacher gave me advice when I want to charge any device, I should plug the charger into the device before plugging the other end into the electrical outlet. Why?? Does it have to do with preserving the device or the battery? Additionally, when finished charging the device, it's important to first unplug the end connected to the device from the electrical outlet before disconnecting the charger from the device.

Hi Team, While a DMA operation is launched, the memory is it accessible for reading or do we have to wait until the DMA is finished? What is the best mechanism to process saved data from DMA ?
