EXTI->IMR1 |= BIT21;//COMP1 Output 中断屏蔽失效 EXTI->RTSR1 |= BIT21;//COMP1 Output 上升沿触发 EXTI->FTSR1 |= BIT21;//COMP1 Output 下降沿触发 } 上述配置中断部分的 BIT21,是通过手册查表Table 98: EXTI lines connections来的(手册Page449)。 根据上图可以看到,line21就是COMP1output总线。
Front Porch This is the area of the video waveform that sits between the start of horizontal blanking and the start of horizontal sync. Genlock When two cameras are genlocked, their internal sync circuits are driven by a common external source. These cameras output video frames synchronous to ...
Almost works, thoughcompositor.clearis pretty ugly here, as we would be blanking all surfaces for but I have also seen another variant of this issue, where drm leasing fails, because we are using too much bandwidth. So now we suddenly need to keep resource usage low, while another process...
