Hi, everyone~~ It's time for our weekly review again, come and have a look~ Recommended wonderful posts: @littleshrimp GD32-Colibri-F350Rx Review GD32-Colibri-F350Rx (GD32F350) Development Board ADC Routine GD32-Colibri-F350Rx development board related resources @懒猫爱飞 Which BLE chip development project do you use? Da14683 Learning Log (I) -- Summary of Central Demo Routine Learning

Because I have been working on the usb_hid_dongle project recently, I have explored central a lot. Now I will analyze and summarize the ble_cntral project first, and then make a study note on the ble_peripheral routine. If time permits, after finishing the notes on ble_peripheral, I will organize other routines one by one. This is a later story. Now I will organize the central routine. [/quote] @RCSN A brief discussion on timer gameplay (time polling method)

Often speaking, for some uncomplicated microcontroller applications, which have strict requirements on memory and storage, and need to process some specified tasks in multiple time-sharing modes, it is a common practice to use a hardware timer to establish various task time flags when RTOS cannot be used. However, with the increase of time flag variables, code maintenance and simplicity become increasingly difficult. Therefore, the author uses a time polling method similar to thread management (maybe the term is inappropriate) to simulate multiple software timers (hereinafter referred to as threads) with a hardware timer, supporting interfaces such as thread registration, deregistration, suspension, wake-up, and processing.
