Hello, community!
I am only new in EVE, now I am connecting the first my screen with FT813.
Can someone explain me, how to display several coprocessor display lists on one screen. Unfortunately, I couldn’t understand this from the EVE FT81x programming guide.
I need to displays many text data and draw couple diagrams. And I came to the fact that everything I want to display does not fit in one display list. When I try to execute one display list, and then without giving the CMD_SWAP command, load and execute the second display list, I get a completely broken image on the screen.
Here is a display function that is called every 20 ms (I simplified it). Please tell me what's wrong with it!
void TFT_loop(void)
{
   uint8_t temp_c;
uint16_t temp_16;
// uint32_t temp_32;
uint16_t Y;
static uint8_t Data[128];

if(tft_active != 0) {

      for (temp_c = 3;temp_c < 77;temp_c++) {Data[temp_c] = temp_c;}
Data[0]++;
Data[1] += 2;
Data[2] += 3;

Data[77] += 3;
Data[78] += 2;
Data[79] += 1;

And here is what I want it to display:


And what I get, instead:
