SigmaStudio+ Indirect Parameter Accees Table
In old SigmaStudio you could add a parameter to the IPAT with a simple mouse right-click. Is there a similar feature in SigmaStudio+? I can only add it via the IPAT table but it gets annoying when the

Indirect Parameter Access Table
Hi, Having issues with the IPAT. I have enabled the proper options, built a table, did the update, recompiled and then stored to EEPROM. For some reason, I cannot access the IPAT addresses, just the o

USBi programmer issues (EVAL-ADUSB2EBUZ)
Hello everyone, When we started our DSP project, we got some Chinese USBi programmers with our DSP Devboards, which didn't seem to be of the best quality, so to improve our reliability we decided to b

Which Registers control SPI Mode and other configuration?
The datasheet warns that "The master port must be reconfigured in software before using a protocol other than the one configured at boot time." So, how is this done? Which Registers control this confi

Programming ADAU1761 using Sigma Studio Capture Window Address + Data sent from microprocessor Circuitpython via I2C
I am (usualkly) successfully able to use address and data copied from the capture window of Sigma Studio to program an ADAU1761 via I2C. I use CircuitPython running on an nRF52840-based microprocessor

ADAU1701+esp32+micropython
hi. I decided to experiment with adau1701 and esp32, wrote a simple code to turn mute on and off using micropython, ran it on a microprocessor, but it doesn't want to work. I checked the dsp address,

Reset RAM via MCU
Hey Team, Is there a way to clear the DSP RAM via SPI from a MCU ? The datasheet says that after a hardware reset the RAM is not guaranteed to be cleared. I implemented a DSP firmware update mechanism

Is there a way to edit values of cells outside there pre-set limits
I have two of the ADAU1701 chipset and use sigma studio for development, although i get by with the values that are set and there limits. i wish to know if i can go over by a DB or so as a call either

External Master Clock vs I2S
Using ADAU1772, we create a Master Clock with our fpga. It is a little off, 12.262 MHz. I did not change anything in the PLL SigmaStudio tab, wrote the EEPROM with the fpga, and we got the intended si

Can somebody check if my program is OK?
Hello, Could somebody check if there is an error in my program? I'm new to Sigmastudio and don't what to look for at the moment. The first time I loaded this program into my tinysine board the speaker
