TFT_eSPI crashes after a while

[j45p41]

Hi,

carrying on from: https://github.com/sandeepmistry/arduino-LoRa/issues/290.

I have managed to implement code that works but crashes within 24 hours. Did anybody find a fix for this issue?

I am using lgvl but I am sure the issue is related to SPI.

Here is the code that works for while and then crashes:

#include <lvgl.h>
#include <TFT_eSPI.h>

#include <SPI.h>
#include <LoRa.h>
// #include "NotoSansBold15.h"

//define the pins used by the transceiver module
#define ss 33
#define rst 12
#define dio0 27

#define MY_CS       33
#define MY_SCLK     25
#define MY_MISO     27
#define MY_MOSI     26

#define CE_PIN   12
#define CSN_PIN 33
