This will enable the ‘update’ interrupt for the timer. Note that as we did not configure interrupt controller, the interrupt won’t affect our code execution and we’ll have to check for it manually. Replace the contents ofmain()with the following code: InitializeLEDs();InitializeTimer();...
When configuring the STM32 Blue Pill timer module in encoder mode, the timer module works as a digital counter using two input signals. When both input pins have a valid transition, the counter gets clocked. The count pulses are generated by monitoring the sequence of the transitions of the ...
HAL_TIM_Base_Start_IT(&s_TimerInstance); From the main() function you can check the status of the ‘Update’ interrupt and toggle the LED state when the update happens: for(;;){if(__HAL_TIM_GET_FLAG(&s_TimerInstance, TIM_FLAG_UPDATE)!=RESET){__HAL_TIM_CLEAR_IT(&s_TimerInstance...
I left the Interrupt (T_IRQ) pin unconnected for now. This is because the input interface LVGL can work without the interrupt, so I am not connecting that pin.The touch interface also uses SPI, so we need to enable another SPI to connect the touch interface. Below is the picture ...

As we have seen in the last STM32 Blue Pill UART tutorial, In the polling method, microcontroller will do nothing except polling the state of the RX pin. Therefore, it is kind of a waste of microcontroller processing time and resources. On the contrary, by using an interrupt-driven approac...
There are some situations when the slave device can not keep up with the master. The device might be a little slow, or there might be some high priority interrupt it has to serve. In these situations, clock stretching allows the slave device to hold the clock pin low for some additional...
The STM32 MCUs have an extended interrupts and events controller which manages the external and internal asynchronous events/interrupts and generates the event request to the CPU/Interrupt Controller and a wake-up request to the Power Manager. ...
