Loading dsp data using esp32 holds i2c lines low
On ESP32 I program the ADAU1452 DSP over a shared I2C bus during startup (bulk writes of the DSP image). During this DSP load phase I have observed, on a logic analyzer that both I2C lines (SCL and SD

Understanding of gain stage, dsp headroom and serial port bit rates
Hello Ez, I am trying to properly understand the relation between gain stage, DSP headroom and serial port bit rates as the title says. The DSP is used as an active XO for stereo systems. It could be

Read/Write to EEPROM does not work anymore, but selfboot does
I've built a custom ADAU1452 board with a Winbond W25Q SPI flash. I have used this board with no issues for the last 6 months or so but I had to reconfigure it and for some reason I can't write to the

Programming ADAU1452 via I2C in SigmaStudio+
I have used SigmaStudio 4.7 for programming ADAU1452 via I2C, using a "custom" USBi. However, I can't seem to do that in the new SigmaStudio+. Using a custom platform block, there isn't a way to conne

DSP Readback is not working
I have a problem with the USBi 1.5, EVAL-ADAU1452REVBZ, and SigmaStudio 4.7 on Windows 10 Pro (22H2) where none of the DSP Readback blocks in my setup read anything but FFFFFFFF. Power (6V) is applied
