include files generations bug?
Hello,
I'm developing an application with ADAU1761
When I export a project the include file xxx_CODEC.H has some
variable with a incorrect name, for istance:
ADI_REG_TYPE R29_DSP_RUN_REGISTER_Default[REG_DSP_RUN_REGISTER_BYTE] = {
0X01
};
the DSPRUN register in the ADAU1761 is R62.
I'm also confused because in the datasheet the registry size is always 1byte but I found some initialization with multibyte
like this
/* Register Default - CODEC.Watchdog Registers */
#define R19_WATCHDOG_REGISTERS_SIZE 5
ADI_REG_TYPE R19_WATCHDOG_REGISTERS_Default[R19_WATCHDOG_REGISTERS_SIZE] = {
0X01, 0X00, 0X00, 0X00, 0X00
};
in the datasheet page 50 the watchdog register R56 has a size of 1byte

Hi Stephano
Correct, I have seen this problem, I believe is related to the export file generation fixes we recently introduced. I'll make sure our software team is aware of his concern and fixes it in the next SigmaStudio release.
Best regards

Hi Stefano,
The “R29” in the export file just means it’s the 29th default register value, it is unrelated to the actual register in the datasheet. Sorry for the confusion. The internal numbers in the export files code are simply unrelated to the datasheet numbers. However, the really important portion is just the address and data, so that should all be correct.
What's happening here with the register lengths is that there are multiple, sequential registers that are written in one burst write. There are actually 5 watchdog registers, as you can see here:
Basically, SigmaStudio is just writing all five of those in one burst, instead of 5 individual writes. You are free to do whichever you choose.
