The buzzer is a hardware device on the s3c6410 Development Board. You can control the buzzer by writing a specific value to the register. This chapter implements a complete buzzer driver (which can be turned on and off) when the driver is implemented differently than the LED PWM drive will consist of multiple files. This is also the standard implementation of mos

1th. Android system porting and driving development Overview1.1 Android System ArchitectureAndroid is a very good embedded operating system. After several years of development and evolution, Android has evolved to form a very well-developed forest system architecture.Android's system architecture is divided into 4 tiers: The Linux kernel, the C + + code base, the

module AUTHOR macro. Module Description: Specified using the module DESCRIPTION macro. Module aliases: Specified using the module alias macro. The open source protocol is specified using the MODULE LICENSE macro. In addition to this information, the Linux driver module itself contains this information. The Word_count driver for counting the number of words is th

I wrote an LED driver over the past two days and read many posts online. The idea is very clear at first, that is, first look at the circuit diagram and find that the LED lights are connected to the GPM port, Then, let's look at the data manual, first to gpmcon port write command words, let the GPM0-5 set to output, and then write data to the gpmdat port, in the GPM0-5 pin to pull low or pull high level, To control the LED lighting. 1. Circuit Diagram

25. Linux-Nor Flash Driver (detailed description), 25. linux-norflash 1. nor hardwareIntroduction: From the schematic diagram, we can see that nor flash has an address line and a data line. It is similar to our SDRAM interface and can directly read data, but it cannot directly write data like SDRAM. It requires commands. 1.1 of US 2440There are 27 address lines

The eighth chapter introduces the experiment: Buzzer driver, let the development board make sound.This paper introduces the principle of buzzer and realizes a complete buzzer driver, which can control the opening and closing of buzzer.The buzzer is also called PWM pulse width modulation, the basic principle is to control the buzzer by the pulse to open and stop.
