esp32UTFT彩屏库不能将数据存到闪存怎么回事？

如题用PROGMEM语句把一串数组存到闪存里了
const uint16_t newint[4096] PROGMEM = {0Xffff,0Xffff,0Xffff,0Xffff....};
然后调用时报错UTFT_Demo_160x128_Serial_HW:322:42: error: invalid conversion from 'const uint16_t* {aka const short unsigned int*}' to 'short unsigned int*' [-fpermissive]
myGLCD.drawBitmap (0, 0, 64, 64, newint,2);
库函数声明是void UTFT::drawBitmap(int x, int y, int sx, int sy, bitmapdatatype data, int scale)
读闪存的代码是
pgm_read_word(&data[(ty*sx)+tx]);
这个代码在UNO上跑起来是没问题的能出图，也不会报错

我的utft库底层函数默认读取esp32的flash存储区，把底层函数修改成读取程序里的变量就行
