Description: One of the most important issues affecting
the implementation of microcontroller
software deals with the data-decision
algorithm. Data-decision refers to decoding
the DIO-pin from the CC400/CC900. Two
main principles exist for decoding
Manchester-coded data: Data decision
based on timing the period between
transitions, and data decision based on
oversampling.

Description: 采样率小于一个连续时间信号最大频率的2倍时就叫undersampling，欠采样，根据抽样定理，当fs>=2fmax，也就是oversampling，过采样时，数字信号才能重建成原来的模拟信号，欠采样重建会发生混叠

Description: 使用STM32单片机ADC模块的过采样技术使采样值更稳定，是一种时间换精度的方法。-This firmware gives the STM32 ADC oversampling using triangular dither. This method
consists on adding a triangular signal to the input signal and sampling it with
a rate.
The timer TIM2 is used to generate the input signal sampling frequency.
The STM32 ADC1 clock is configured to 14Mhz and the channel 10 is converted (PC.00).
The triangular dither is generated using the Timer TIM3.
After OSR DMA transfer from the ADC data register to a buffer in RAM, the new
sample is computed.
