LP5569: Breathing Effect

I have confusion about the highlighted numbers. From where 0x09,0x78,0xa8 came from?

Why the loop is from 0 to 16? Why i+j*32 is used?

0x09, 0x78, 0xa8 are the ENGINE1/2/3_PROG_START Register.

You can find these data from the .hex file.

The for loop is used to shift the 32*16 bytes data array to the chip SRAM through i2c.

Ok I got it. But now I am facing another issue.  My writes are not properly going to SRAM. When I write to page 0 on addresses 5a,5c,5e,60,62,64,66,63 any value and when I read back from these addresses I always get 00. Other addresses are giving right values. but something is wrong with these addresses. I also tried writing 00 to whole memory and reading back I get all zeros. which means that my writes are getting to the memory. I have attached the file in which I have written the data gathered from logic analyzer. First column is for random values written on page 0 of memory and 2nd column show writing 00 to page 0. I have highlighted these addresses with red. Please have a look at code also.

I have already enabled auto-increment and i'm using internal clock, no charge pump.

Did you get the LED ON without SRAM? Like the following register setup.
