麻烦用过131芯片或类似芯片的朋友
如果我需要对输出的图像进行jpeg压缩20倍的话
应该如何控制呀
芯片手册上好像没有设置压缩多少倍的参数
芯片上有这个参数
Watermark of the output FIFO.
00: Less than 25% full
01: 25% to less than 50% full
10: 50% to less than 75% full
11: 75% full or more.
Watermark is cleared when the host or microcontroller writes “1” to bit 4 of this register
