看到datasheet里面讲PWR5(general purpose BUCK1)和PWR7(general purpose BUCK3)是不能用的,在未来可以使用。那么现在的DLPA3000可以使用这两个PWR吗?

目前最新的DLPA3000D暂不支持PWR5、PWR7输出,具体请参考对应的规格书。General Purpose Buck2 (PWR6) currently supported, others will be available in the future.
打开DLPA3000的GP-Buck2的5V输出,发以下I2C命令给DLPC3438:
# Addr write
W 36 eb 14 00 00 01 00
# Write value to register
W 36 ec FF
DLPC3438的14h寄存器是调整图像的水平、垂直翻转。DLPA3000的14寄存器是调整GP-Buck2的电压输出大小。
