“UartTFT.ini”. The command file consists of two parts, one is the TFT serial panel information 
setting [INFO], and the other is the TFT serial panel command setting [USERCMD] detail

Most of the above information settings are provided by ER-TFT028A2-4-5465 TFT serial panel 
manufacture . The manufacturer of the TFT panel will provide the above information 
according to the characteristics of the TFT panel and the hardware design. With the 
information, users only need to add them to the beginning of the command file. For example, 
if the TFT serial Panel is a 240*320 TFT Panel, the XSIZE and YSIZE must be set as follows: 

 

XSIZE: 240                              
YSIZE: 320 

 

The resolution of the TFT panel is fixed at the factory. The user only needs to add the [INFO] 
information provided by the manufacture to the front of the command file, so that the 
information of [INFO] is settled.
