I watched YouTube and followed it. This is to display the voltage coming into ADC IN0 on the LCD.
I used the TouchGFX + CubeIDE compiler, but an error occurred.
On YouTube, it compiles normally. Please let me know why the error occurred.

I saw your YouTube and tried it. However, some errors have occurred.
Some variables are not declared, how can I solve them?
void Screen1View::analogUpdate(uint32_t value)
{
memset(&textAreaADBuffer, 0, TEXTAREAAD_SIZE);
Unicode::snprintfFloat(textAreaADBuffer, sizeof(textAreaADBuffer), "%.3f", value * 0.000805664 ); // 3.3/4096 = 0.000805664
textAreaAD.invalidate();
}
I tried to display the analog input voltage on the LCD screen, but an error occurred in the screen viewer function. The problem made me sick for a week. I want to upload a proper YouTube. The person who uploaded YouTube wants to upload in detail how the error did not occur.
Can someone please help me.
It seems crazy.
