A maximum number of PWM channels (Pins) are available on the ESP32 - 16 channels, but only 8 different PWM frequencies are available, the remaining 8 channels must have the same frequency. On the other hand, 16

On the ESP32 ADC functionality is available on Pins 32-39. Note that, when using the default configuration, input voltages on the ADC pin must be between 0.0v and 1.0v (anything above 1.0v will just read as 4095). Attenuation must be applied in order to increase this usable voltage rang...

前面的博客使用了第一种方式,然后也将C数组存储在sd卡,然后读取sd数据,构建lv_img_dsc_t结构体来进行描述。但是可能是构建的数据不对,或者 lvgl不太兼容这种方式,显示效果不好,图片有很多噪点,所以想了想,当图片数据在sd卡上时,还是的用第二种方式。
