Why use serial screen
The arrival of the era of color, but also with low black and white screen design products? Out of date!
SCM direct drive color, requires a lot of IO, increase the complexity of the system, the hardware design cycle length
Software design need to extract your own font, the size of the dot, different fonts, and even graphics, icons processing requires a lot of code, the software design cycle length
Design interface every time you need to compile the code, complex and inefficient;
Application Serial screen, write with a serial data output can drive a variety of dot matrix display Chinese characters and graphic icons, Easy!
A new generation of serial panel prices have been up close to the black and white display with no processor price!
Usart which means that the serial port; GPU mean microcontroller with a graphics processor; the purpose is to do microcontroller dedicated graphics processor;
The system uses 32-bit ARM core microcontroller + SPI memory and performance cost in sufficient advantage.
Parameters
Voltage: 3.5V ~ 5.5V（Found 3V can work properly, lithium batteries can directly drive）;
Usart serial mode, TTL level, supports baud rates from 2400 to 256000, 115200 default;
Memory: 4M bytes;
Only need a minimum of IO to drive, using a microcomputer, TX transmitting side;
Horizontal and vertical screen display support; optional four directions;
Comes Store, 12, 16 dot matrix GB2312 support all the characters and 24,32,48,64 lattice small font characters and character, the small size of each font can store 512 characters and character, but all does not allow small font ultra 384K length
Serial transmission of data non-binary coding, but the use of statements mode, convenient human-readable display kanji characters strings can be directly transmitted, without transcoding numbers easy to read and debug;
Serial command buffer 1024 bytes for easy transmission of large amounts show a statement, the effect of increasing the UI;
Basic graphics support point, line, circle, block, block, etc. filling display;
Support graphics display, the maximum allowable 512 graphics, but the total length may not exceed 1M bytes（Each figure representing: L * W * 2）
Part of the support ICON class, automatically intercept the whole image display（The Big Picture mode is determined by the composition of the same size ICON）
Support background images and characters superimposed display（12 dot matrix does not support）
Support Internet download firmware upgrades
