[Under verification] 4.41-inch ink screen

Project Description

Precautions:

Bao Yuan is shameful, and I strongly complain about this behavior. .

The project is still capturing signals, and the time period will be relatively long. I hope that a big boss will sponsor an Agilent to continue.

IC picture conversion code

static byte[] convertTo1bit_PixelFormatType0(byte[] picData, int w, int h)
{
byte[] newRow = new byte[picData.length * 1 / 8];
// join nibbles (so 1 byte is 8 pixels)
int j = 0;
for (int i = 0; i < picData.length; i += 8)
{
newRow[j] = (byte)( ((picData[i + 0] << 7) & 0x80) |
((picData[i + 1] << 6) & 0x40) |
((picData[i + 2] << 5) & 0x20) |
((picData[i + 3] << 4) & 0x10) |
