其中触摸滤波方法是检测到触摸后先延迟30ms,消除抖动,然后采集10组坐标值做升序排列,去掉最大的几组坐标和最小的几组坐标,对中间的几组求平均作为最终的数值(电容触摸芯片返回的是ADC数值,不是实际坐标值)。然后将最终的数值代入通过触摸校准建立的线性公式来获得实际的坐标值,此时就可以将触摸坐标和触摸按下状态...
Describe the bug Starting an adc scan sequence of more than 8 channels does not work on STM32H7 Tested on nucleo_h723zg with adc_sequence sample To Reproduce create an overlay for the stm32h723 in the board folder of the adc_sequence sam...
STM32 F4 ADC DMA Temperature Sensor Goal:detecting temperature variations using a temperature sensor, ADC with DMA and TIM3 as a trigger (ADC sampling frequency = TIM3 trigger frequency). Note:Using TIM3 as a trigger is suited for monitoring temperature variations over time. However, this is ...
在停止模式下,如果在进入该模式前ADC和DAC没有被关闭,那么这些外设仍然消耗电流。通过设置寄存器ADC_CR2的ADON位和寄存器DAC_CR的ENx位为0可关闭这2个外设。 退出停止模式 当一个中断或唤醒事件导致退出停止模式时, HSI RC振荡器被选为系统时钟。
4.3.1.Software Tools↑ STMicroelectronics offers some software programs that allow the users to program and allow the application using the boards and the MCUs: STM32CubeIDE STM32CubeMX STM32CubeMonitor X-CUBE-MCSDK... But STM32 is also compliant with: ...
If you are directly using an uncompressed kernel, which is more rare, you should also make sure that it is loaded at an optimum location, so that there is no need to move it before starting it. Building a Linux system for the STM32MP1: implementing factory flashing ...
