CH549EVT development board test - solution to the problem of data segment exceeding the limit [Copy link]

After completing the driver of LCD5110, I started testing the timer. After adding timer.c, the compilation failed. A careful inspection revealed that the data exceeded the limit (see screenshot), data=151.6, far exceeding the limit of 128.

Before this, data=101.5 (see the figure below), so it can be compiled normally.

I carefully checked the program and found that the touch button occupied the data memory. The UINT16 PowerValue[16] data alone took up 32 bytes. For this reason, I compressed the data index to 8 and compressed another related array UINT8C CPW_Table[16] by half. After compilation, data=71.5.

After testing, the touch buttons function basically normally and the memory occupied by data is reduced by 30 bytes.
