Also irgendwie will da grad gar nichts klappen.
Hier ist der Beispielcode von dem Shield:
#include "EPD.h"
#include "GUI_Paint.h"
#include "EPD_SDCard.h"
void setup() {
DEBUG("7.5inch e-Paper B and C demo\r\n");
DEV_Module_Init();
EPD_7IN5BC_Init();
EPD_7IN5BC_Clear();
DEV_Delay_ms(300);
#if 0
/*show sd card pic*/
//1.Initialize the SD card
SDCard_Init();
//2.Create a new image cache named IMAGE_BW and fill it with white
//Draw black picture
DEBUG("IMAGE_BW\n");
Paint_NewImage(IMAGE_BW, EPD_7IN5BC_WIDTH, EPD_7IN5BC_HEIGHT, IMAGE_ROTATE_0, IMAGE_COLOR_INVERTED);
Paint_Clear(WHITE);
//3.Read BMP pictures into RAM
SDCard_ReadBMP("7in5b-b.bmp", 0, 0);
//Draw red picture
DEBUG("IMAGE_BWR\n");
Paint_NewImage(IMAGE_BWR, EPD_7IN5BC_WIDTH, EPD_7IN5BC_HEIGHT, IMAGE_ROTATE_0, IMAGE_COLOR_INVERTED);
Paint_Clear(WHITE);
SDCard_ReadBMP("7in5b-r.bmp", 0, 0);
//4.Refresh the picture in RAM to e-Paper
EPD_7IN5BC_Display();
DEV_Delay_ms(2000);
#endif
#if 1
//1.Create a new image cache named IMAGE_BW and fill it with white
//Draw black picture
Paint_NewImage(IMAGE_BW, EPD_7IN5BC_WIDTH, EPD_7IN5BC_HEIGHT, IMAGE_ROTATE_0, IMAGE_COLOR_POSITIVE);
Paint_Clear(WHITE);
//2.Drawing on the image
Paint_DrawPoint(25, 50, BLACK, DOT_PIXEL_1X1, DOT_STYLE_DFT);
Paint_DrawPoint(25, 70, BLACK, DOT_PIXEL_2X2, DOT_STYLE_DFT);
Paint_DrawPoint(25, 90, BLACK, DOT_PIXEL_3X3, DOT_STYLE_DFT);
Paint_DrawPoint(25, 110, BLACK, DOT_PIXEL_4X4, DOT_STYLE_DFT);
Paint_DrawLine(50, 50, 150, 150, BLACK, LINE_STYLE_SOLID, DOT_PIXEL_1X1);
Paint_DrawLine(150, 50, 50, 150, BLACK, LINE_STYLE_SOLID, DOT_PIXEL_1X1);
Paint_DrawLine(100, 200, 100, 300, BLACK, LINE_STYLE_DOTTED, DOT_PIXEL_1X1);
Paint_DrawLine(50, 250, 150, 250, BLACK, LINE_STYLE_DOTTED, DOT_PIXEL_1X1);
//Draw red picture
Paint_NewImage(IMAGE_BWR, EPD_7IN5BC_WIDTH, EPD_7IN5BC_HEIGHT, IMAGE_ROTATE_0, IMAGE_COLOR_POSITIVE);
Paint_Clear(WHITE);
Paint_DrawRectangle(50, 50, 150, 150, RED, DRAW_FILL_EMPTY, DOT_PIXEL_1X1);
Paint_DrawRectangle(200, 50, 300, 150, RED, DRAW_FILL_FULL, DOT_PIXEL_1X1);
Paint_DrawCircle(100, 250, 50, RED, DRAW_FILL_EMPTY, DOT_PIXEL_1X1);
Paint_DrawCircle(250, 250, 50, RED, DRAW_FILL_FULL, DOT_PIXEL_1X1);
Paint_DrawString_EN(10, 310, "hello world", &Font24, WHITE, RED);
Paint_DrawString_EN(10, 335, "Waveshare Electronics", &Font24, RED, WHITE);
Paint_DrawNum(10, 360, 123456789, &Font24, RED, WHITE);
//3.Refresh the picture in RAM to e-Paper
EPD_7IN5BC_Display();
#endif
DEV_Delay_ms(4000);
EPD_7IN5BC_Clear();
EPD_7IN5BC_Sleep();
DEV_Module_Exit();
}
void loop() {
}
Wenn ich den ausführe, bekomme ich im seriellen Monitor nur umgedrehte Fragezeichen und manchmal auch andere Zeichen angezeigt.
Hier ist der Demo-Code vom Display:

Wenn ich den versuche, auszuführen, bekomme ich die Meldung, dass der Sketch zu groß ist und 199% des Programmspeicherplatzes belegt.
Bin grad echt am Verzweifeln und weiß nicht, warum keiner der 2 Demo-Codes klappt.
Könnte mir u. U. jemand weiterhelfen?
Danke schon mal und liebe Grüße
