Super
Recomand,
cu lib. TFT_eSPI si ESP32
pana la 100fps si 33MHz SPI frecv
Excelent
Un display bun.
Este bazat pe controllerul ILI9341.
Atentie insa: display-ul are ca tensiune maxima 3.3V. Ceea ce inseamna ca are nevoie atat de alimentare la 3.3V dar si pinii de date au nevoie tot de 3.3V. Este recomandat sa folositi un CD4050 daca aveti o placa de dezvoltare (ex. Arduino) care functioneaza la 5V.
Am reusit sa comunic in modul SPI HW cu libraria ADAFRUI ILI9341(https://github.com/adafruit/Adafruit_ILI9341)
Daca folositi libraria Adafruit, in exemplul "graphictest", la pinii HW spi trebuiesc declarati pinii pe care ati conectat DC, CS si RST, dar in exemplu, lipseste pinul de reset... (vezi mai jos:)
Initial, astfel sunt declarati pinii pentru HW SPI:
#define TFT_DC 9
#define TFT_CS 10
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);
la mine a functionat cu urmatoarea modificare:
#define TFT_DC 9
#define TFT_CS 10
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341 tft = Adafruit_ILI9341(10, 9, 8);
Unde 10 -pinul DC al display-ului, 9 - pinul CS si 8 pinul Reset al display-ului.
NU UITATI de level shifter-ul 4050. In caz contrar, display-ul va ramane alb.
