安富莱电子推出emwin教程,共60期。论坛:http://bbs.armfly.com/本期教程主要是跟大家讲解一下抗锯齿,关于抗锯齿,在第16章讲解字体显示的时候也讲了点。本期教程就是跟大家详细的讲解一下抗锯齿方面的知识。 线条由一系列必须位于显示坐标处的像素近似构成。因此,可能看起来呈锯齿状,尤其是近似水平线或近似垂直线。这种现象称为锯齿(aliasing)。抗锯齿是对线条和曲线进行平滑处理。可以减少不完全水平或垂直的线条的楼梯状锯齿。STemWin支持不同的抗锯齿质量、无锯齿字体和高分辨率坐标。- Armfly Electronics launched emwin tutorials, a total of 60.

ADXL362是一款超低功耗、3轴MEMS加速度计,输出数据 速率为100 Hz 时功耗低于2 μA ,在运动触发唤醒模式下功耗 为270 nA 。与使用周期采样来实现低功耗的加速度计不同, ADXL362没有通过欠采样混叠输入信号;它采用全数据速 率对传感器的整个带宽进行采样(The ADXL362 is an ultra-low power, 3 axis MEMS accelerometer with output data When the speed is 100 Hz, the power consumption is less than 2 A, and the power dissipation in the motion triggered wake-up mode For 270 nA. Unlike using periodic sampling to achieve low power dissipation, accelerometers are different, ADXL362 does not aliasing input signals via undersampling; it uses full data speed The rate is sampled across the entire bandwidth of the sensor)
