AD1939 in selfboot system
Hi! I have a SW/HW question about programming the AD1939 CODEC in a Selfboot ADAU1446 DSP-System. My board works well with the ADAU1446 in I2C Mode, with selfboot from EEPROM (I2C) and with the AD1939

First value read by ADC can vary from chip to chip?
I'm reading an Aux ADC and then holding the minimum value with a slow release time. This has only been a problem on 1 out of 7 prototypes, but on that one, the value is held much lower than it should

How do I start a timer after power-on, or when the input signal goes away?
How do I start a timer when the SigmaDSP powers on, and then output a GPIO flag when the timer is complete? This could be used, for example, in power sequencing for a system that requires staggered st

How do I self-boot multiple SigmaDSPs in a single system?
If there are multiple SigmaDSPs in a system, they will all attempt to boot from an EEPROM at address 0xA0. How can a system with multiple SigmaDSPs use the selfboot function but have unique programs i
