1, syn480 is a receiving chip 480r chip parameters , only buy this chip 480r chip parameters , then the peripheral component configuration can be difficult 480r chip parameters , It is better to buy a ready-made receiver module, plus the power supply and antenna can be used>480r chip parameters . As for whether it can be directly connected to the MCU, it is possible. But the problem is, directly connected to the MCU, the received decoding of any need to write a program to complete. In fact, the received signal is determined by the sent signal, how the sending end is encoded.
2, input/output interface (I/O interface) PW113 supports computer image input signals from VGA to UXGA resolution (1600×1200p), and the maximum pixel resolution of output is SXGA (1280×1024p).
3,The second reason: that is, the performance of the main chip of the graphics card decreases, the chip resistance, capacitor, and transistor connected to the VAG have problems, the graphics card BIOS appears confused, and the graphics memory appears virtual welding, which will cause the boot screen, or the screen in use, processing method: repair the graphics card or replace the graphics card.
4, I2C: Only two wires are needed to transmit information between devices connected to the bus. SMBus: Provides a control bus for tasks such as system and power management. SMBus is used to send and receive messages between devices through the SMBus, rather than using a separate control line, which can save the number of pins of the device.
5, other signals CLK: clock signal (input) VCC: power supply, +5V± 10% Ground: ground. The two ground lines commonly used signal pins AD15 ~ AD0: address/data AD19 ~ AD16 / S6 ~ S3: address data/status BHE× / S7: high permit (output) MN/MX× : maximum and minimum (output) M/IO× : memory/IO (output) Dt/R× : data transmission/reception.
6, we are looking forward to USB masterContinuous optimization and development make USB0 play a truly fast role. The speed of reading and writing speed of U disk further affects our work efficiency, in order to make U disk reading and writing speed fast, we must first understand the two points that hinder the speed of U disk, in order to choose a good quality when buying U disk, the main control chip and Flash chip to speed up, the speed of U disk is not a problem.
