前端主控接6540的I2C0。具体的I2C协议和相关寄存器请参考6540的Programmer Guide: https://www.ti.com/lit/ug/dlpu110/dlpu110.pdf?ts=1627529914911&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDLPC6540%253FkeyMatch%253DDLPC6540%2526tisearch%253Dsearch-everything%2526usecase%253DGPN
你好,我这边通过前端主控去修改VBO的配置,将默认的Byte Mode 1改为2,修改不了,我这边写的是0x34,0x30,0x00,0x02,0x08,0x00,如下图,是我这边的命令不对还是6540的固件需要定制呢?
DLPC6540现在使用的固件是DLP471TP_EVM_v3.2.2_MCU_Fv3.2.6.img
发送的命令不对,少了length和checksum。建议你试一下不用checksum和ACK,只有length,命令如下:
Write Vbo Configuration | 14 30 04 00 00 02 08 00 |
