hi sir,
with ADC5140 EVM,we wanna use ap(AudioPrecison) measurements by adc path,
for example,audio input and output,how can we use the GUI testtool with ap??

Hello,
You will use the PPC3 GUI to configure the device registers and get the device in the proper state for the Audio Precision connections. You will need to set the S0 switch on the AC-MB to "OFF" for External ASI and then the AP will connect on the AC-MB motherboard on the J7 "External ASI" connector.
These connections are shown in the EVM User's Guide, search for "External ASI".
hi sir,
i got it,and after i test it with external ap,and if some problems, i will ask you.
thanks
hi,sir
i have got the evm,and i open the PPC3,and evm connect to my pc with usb interface,and PPC3 gui,just show the installed EVM name:I2C MASTER,and no tlv320ADC5140 app title,and how can i open the adc5140 control app??
hi sir,
i got the adc5140 access right,and already connectted the target evm,
thanks
hi sir,
with ap,i have a test suit,please help me check
1.ap with adc5140 INP/INM input analog signal with balance or unbalance,
2.adc5140 with IIS output digtal signal,and output connect ap digtal serial in
3.ap check the adc5140 with adc audio path value,such as snr,waveform,so on...
Is there anything wrong with my test method?
Hello!
It would appear that the access to the ADCx140 application was delayed which is why you did not see it. I have confirmed access has been granted now for the application. Launch PPC3 and log-in using the same myTI account information this E2E thread is associated with.
In regards to the testing question, your test methods are proper and this is the same high-level flow we follow when testing. Be sure to enable "A-weighting" filters to match the same datasheet performance.
but as below,when i test ,and PPC3 GUI whether config some registers or not??
such as ,i test INP/INM and output IIS
with me hw connections board, and ap send analog single signal, and adc5140 output iis signal connect to ap
please check me attachment
and GUI config also help check
hi,sir
For the above test path, the IIS output of ADC5140 is master and synchronous clock data is sent to AP.
but found the board IIS pin ,have no waveform,i think ,there is ADC5140 config wrong??
please help me check??
Hi User,
It's a little hard to see the screen images but it doesn't look like you have any output channels enabled to Slot-0/Slot-1 for the 2-channel out I2S configuration it looks like you're trying to achieve.
Also, it looks like the audio signals are possible connected in the wrong polarity from the AP. The GND connections are on the outside of the board as the labels on the board show. You posted another thread with similar information which I'm going to close.
