The below display partial does not work. The single digits does not get updated instead only the 10th digit got updated.
'#include "Adafruit_ThinkInk.h"
ThinkInk_290_Grayscale4_T5 display(EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY); //ThinkInk_154_Mono_D67 display(EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY);
void setup() { Serial.begin(115200); // while (!Serial) { delay(10); } // Serial.println("Adafruit counter"); display.begin(THINKINK_GRAYSCALE4); display.setRotation(0); }
uint16_t counter = 0;
void loop() { display.clearBuffer(); display.setTextSize(4); display.setTextColor(EPD_BLACK); display.setCursor(32, 32); display.print((counter / 1000) % 10); display.print((counter / 100) % 10); display.print((counter / 10) % 10); display.print(counter % 10);
if ((counter % 10) == 0) { display.display(false); } else { // redraw only 4th digit display.displayPartial(32+(243), 32, 32+(244), 32+(4*8)); }
counter++;
}'
tbh partial updates never worked very well in this librayr. you could try gxEPD or gxEPD2!
