本文基于STM32F103RBT6微控制器,深入源码,详细分析了时钟中断处理程序Systick_isr。1. Systick_isr源代码static volatile clock_time_t current_clock = 0; static volatile unsigned long current_seconds = 0; static unsigned int second_countdown = CLOCK_SECOND; //详情见2.1 /***时钟中断处理程序***/ ...
我無法理解當 ModusToolbox 產生專案時如何呼叫 systick 計時器 ISR。通常,當您設定 systick 定時器並啟用其中中斷時,將直接從中斷向量呼叫 Systick_Handler。 我仍然可以看到Systick_Handler是startup_psoc6_02_cm4.s檔案中的那個。 但看起來它不是服務 systick 中斷的實際函數。 相反, Cy_SysTick_ServiceCallb...
I'm failing to understand how systick timer ISR is being called when the project is generated by ModusToolbox. Normally, when you setup the systick timer and enable its interrupt, Systick_Handler is called right from the interrupt vector. I can still see that Systick_Handler is the one ...
