Here is a piece from STM32F746 Reference manual, page 653, TIM1/TIM8 section. Timer reload value is 36, after that update event happens, Update Interrupt Flag (UIF) is set, and the counter starts over. CK_PSC is a clock prescaler. Timer counter is incremented only every presca...
Same thing go with TIMER 3. For Period=65.535 ms and ARR = 65535, PSC = 167 (Please note that computation are approximatives in this case, but I don't need a very high precision). But there again, interrupt is called twice as slow as I expected (every 131.064 ms ap...

When a device initiates PSM with the network, it sends the two timer values (T3324 and T3412); The PSM cycle/time is the difference between these timers (T3412 minus T3324) as shown in the diagram. Through these timers, the device reports to the network how often and for how long it...

Switch bouncing is the non-ideal behavior of any switch which generates multiple transitions of a single input. To remove the bouncing from the circuit Switch Debouncing Circuit is used.
What is PWM (Pulse Width Modulation)? PWM stands for Pulse Width Modulation; we will get into the reason for such a name later. But, for now understand PWM as a type of signal which can be produced from a digital IC such as microcontroller or 555 timer. The signal thus produced will ...
上位机mcu计划使用STM32L4R9ZIY6。 Thanks, Leo Like Dec 22, 2019 2,086 0 3 Owen_Zhang123 Moderator In response to Leo_liu1 建议选择非standlone的模式,因为20706的I2C引脚和I2S引脚是共用的,在standlone模式下,只能选择SPI控制的codec。 Like Dec 25, 2019 2,172 1...
