Dear comrades: There is a voltage sampling function in my touch screen driver. This function obtains the voltage by reading AC97. There is a small delay program in it: [b]do { ReadAC97 (0x76, &adcData...
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
Ultrasonic tooth cleaning machines have been widely used in the medical field. Most ultrasonic tooth cleaning machines used at home and abroad now use analog oscillation circuits. There are the follow...[Details]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
