Hi,
I'd like to hear from people that worked with those DAC's.
My first question is how do you program them without an EVM?(I know about the SPI/I2C interface ,but my question is related to the Instruction Set or how do i use the DAC's DSP).
PurePath seems to want an EVM otherwise it won't spit out the cfg file or create the configuration instructions to be sent.
Second is where can i find an Instruction ISA handbook or documentation for the mini DSP core?
Let's say i have the Z-Transform/Transforms for my digital filter/filters,I load it into the coefficient memory.How do i specify the summation operations etc. and witch coefficients to some with whom or implement the Z^-1 delays?
Also do i have a chance of making PCM5252 work with the SmartAmp functionality without an EVM?
I understood the PCM5252 ROM has the algorithm loaded,i presume in some of those RESERVED pages of instructions.However i found 0 documentation explicating the memory map other than the general layout.(i only found the datasheet)
Feels like the only tool i have to work with is PurePath ,but support is not available("oficially") for PCM5252.
Worst case i'll use them as pure DAC's and do the DSP on a Cortex M-4 ,but i feel like i paid for features i won't use then.
