Display control terminal program

This resource is the engineering source code of a project I participated in, and it is shared for beginners to learn. It covers ucOS, ucGUI, LWIP protocol stack, USB protocol stack, T9 input method, task priority assignment, etc. In addition, it also includes engineering application codes for drivers of UART, SPI, I2S, SDRAM, NORFLASH and keyboard scan chips. A good choice for beginners.

The following is an introduction to the resource readme.

Original program model:

1. This routine is the use routine of uCOSII2.91+UCGUI3.90A.

2. Instructions for use
   
  (1) Download the compiled hex file to the development board and restart the running code.

 (2) After the code runs, the calibration interface of UCGUI will appear. Click the corresponding area to complete the calibration process according to the instructions, and then enter the routine demonstration interface.


Modified program:

1. Remove UCGUI
2. Increase the LWIP protocol stack
3. Increase the USB protocol stack

4. Add UCGUI
5. Revised display control program
6. Add T9 input method

task prioritization

Note: The addition of tasks cannot be the same as the existing priority
**************** User Created Task ************************

Ethernet related:
  Priority: 3
  tcpip_thread: The core task of processing messages such as sending and receiving packets at the Ethernet network layer
  
  Priority: 4
  ethernetif_input: physical layer receive packet task
  
  Priority: 5
  Upgrade_init: single-mode BDU and ADU upgrade tasks
  
  Priority: 7
  tcp_client: The TCP server hangs when there is no connection or data. Question: How to judge the sudden unplugging of the network cable.
  
  Priority: 6
  tcp_server: TCP client no connection or countless

                            It hangs when it is reported, and does not scan a connection every 2s. Question: How to judge the sudden unplugging of the network cable.
  
  Priority: 8
  udptsk_send: UDP send      
  
  Priority: 9
  udptsk_rcv: hang when UDP receive no data
