Hi,

We have incorporated the above-mentioned registers, as provided by you, into our register set. However, we are currently not receiving any output.

Please find below the final register set that we are using:

(0x21, 0x88, 0x00)

(0x21, 0x54, 0x80)
(0x21, 0xF6, 0x3B)
(0x21, 0x0E, 0x00)

We would also like to clarify one point regarding the register configuration. For offset 0x0E, both data values 0x80 and 0x00 are assigned at different points in the sequence.

Could you please confirm whether this configuration is correct and whether the register at offset 0x0E is expected to be written twice with these values?

Additionally, since we are not receiving the output with the above configuration, we would appreciate it if you could review the register sequence and confirm whether any changes are required.

Thanks and regards
