19.Arduino learning n otebook-- Atmega8 makes the minimum  arduino system                        Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   Atmega8 is the cheapest of the arduino's officially supported chips, so we'll take it to explain how to make the arduino minimum system on the breadboard. Prepare the material 1. One Atmega8 DIP packaging chip 2 .   One 16MHz Crystal Oscillator 3 . Two 22P capaci tors One key, One breadboard and some connected wires. Let's look at this chip A new chip needs to download the arduino's bootloader, which We use the official recommended USBtinyISP to download. Take a look at the pins of Atmega8 and ICSP pins + 5 v connects to VCC GND connect s  to GND D11, D12, D13 connec...

15. Arduino learning notebook--Liquid crystal experiment of 12864            Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  ( Catduino has the same function of Arduino)   12864 is the lattice abbreviation of the 128*64 lattice liquid crystal module . Control chip generally adopts ST7920 or is compatible  with it . The data bus adopts the way of 8-bit parallel port and SPI  serial port. T he 12864 LCD zip font version with   no font version . Font  version does not need to enter again after the Chinese character s   are became  lattice with lattice generator, direct ly  input the Chinese character interior code   can show the corresponding Chinese characters .   No font version  want s  to display Chinese characters, it  only can be driven by its own way according to the lattice...
