Other Parts Discussed in Thread:TAS5755M
你好,
用TAS5755M PBTL模式下,将0x19设为0x35,0x25设为0x01 10 32 45或0x19设为0x3A,0x25设为0x01 01 23 45,都没有声音输出。而将0x19设为0x35,0x25设为0x01 13 02 45或0x19设为0x3A,0x25设为0x01 02 13 45才有声音,但此时有新的问题,请帮助分析PBTL模式下该如何配置,感谢!
0x19 | 0x25 | 有无声音 |
0x35 | 0x 01 10 32 45 | 无 |
0x3A | 0x 01 01 23 45 | 无 |
0x35 | 0x 01 13 02 45 | 有 |
0x3A | 0x 01 02 13 45 | 有 |

您好,
感谢您对TI产品的关注!您其他寄存器的配置是怎么的呢?电路图可以分享出来吗

! I2C Configuration file for TAS5755M in PBTL mode.X1B 00 X06 00 X0A 30 X09 2C X08 2C X14 54 X13 AC X12 54 X11 AC X0E 91 X20 00 01 77 72 X10 02 X0B 00 X10 02 X1C 02 X19 30 X25 01 02 13 45 X07 30X05 00
It seems that we don't "must" have to set the register 0x19 as 0x3A or 0x35 in PBTL mode, and don't need to set 0x25 as 0x0110 3245 or 0x0101 2345, in fact, sometimes, only set as other value it can work properly.
Expect for this two register, shall you explain a little bit which registers are also usually related to finally audio output, we ecpect to figure out the internal audio routes and setting.

我想向您了解,在如下数据手册配置,在您的电路中可以正常工作吗
Register (0x25) be written with a value of 0x0110 3245, Register (0x19) be written with a value of 0x35
Register (0x25) be written with a value of 0x0101 2345, Register (0x19) be written with a value of 0x3A
