After reading datasheet for four days, I finally started to write code yesterday. So far, the capacitive screens I have done include ITE, Solomon, focaltech, EETI, and cypress. To be honest, the driver for writing these things is already familiar, but today I still feel it! ATMEL's capacitive screen is the best. The interface for drivers is perfect, and even the object-oriented idea is used! The Atmel driver is really a pleasure. Now you can experienc

ATMEL Corporation announced the launch of its AT91CAP7A-STK entry-level development kit, designed to evaluate its ProcessorCustom cap Microcontroller(MCU) series of entry-level tools. The custom MCU of cap7 allows designers to transfer from the "ARM7 and FPGA" design to a low one-time R D cost (NRE) Single ChipSolution: the cost per device is reduced by about 30%, and the performance is improved by 8 times. The static power consumption and working po

Most people who have studied single-chip microcomputer know the names of "Water lamp" or "horse lamp". The specific implementation effect is to display a group of changes cyclically according to a fixed rule. For example, if you use a byte length space to realize the "marquee", you can change the value of this Byte as follows: "0000 0001b"-> "0000 0010b"-> "0000 0100b"-> "0000 1000b"-> "0001 10000b"-> "0010 10000b"-> "0100 10000b" -> "1000 10000b"-> "0000 0001b" (loop) For example, to change th

The serial 51 in ATMEL has the same functions as 89C51. Command compatibility. The hex program does not require any conversion.Directly. Listen 51 only adds a watchdog function than 89C51. For other functions of iis51, refer to 89C51..The use of the watchdog is as follows:In program initialization, first write 01eh to

chip communication. Q1, R2, R4, dw2, and four components provide a 12 V voltage for the programmer. R4 and R2 constitute a partial pressure circuit. In normal times, * 13th chip 89C51 (P3.3) output High Level, Q1 conduction, R2 (1 k) Will dw2 (12 V) Down, at this time dw2 voltage from R4, R2 partial pressure, about 3-5 V; when writing a program, the * chip 13th foot (P3.3) Outputs a low level, Q1 cutoff, dw2 (12 V) directly sends to the 31 foot of th

single-chip microcomputer. One end is connected to the RS232 serial port of the computer, and the other end is connected to the GUI interface of the instrument. The single-chip microcomputer receives the SCPI command from the computer Super Terminal and forwards the command to the instrument with the GUI interface for execution. After the instrument executes the instruction, it sends the execution result to the Controller. Then, the Controller transmits the received data to the computer through

I will not talk much about it. I will first copy an introduction from the official website. The new atmel avr Studio 5 Atmel avr Studio 5 is the integrated development environment (IDE) for developing and debugging embedded atmel avr applications. the AVR Studio 5 ide gives you a seamless and easy-to-use environment to write, build, and debug your C/C ++ and your

packet format would be as follows: If the communication is normal, then the chip will return the data, the returned packet format is as followsThe meaning of each data field is the same as the data sent.Based on the examples just given, the data returned are as follows:Because we read the chip serial number, XX is the only part of each chip serial number. This is just a demonstration of the read commands, if other commands, the data field will be more complex, fortunately

Generally, the microcomputer (PC) is composed of the Main Board, CPU, memory, hard disk, and other devices, the single-chip microcomputer means that these devices are integrated into one chip (or some of them are implemented through external chip Extension). The single-chip microcomputer is also called a microcontroller (MCU ), the Chinese name "single chip microprocessor" is literally translated by the English name "single chip microprocessor. MCS-51 single chip microcomputer is the United St
