Original question:

CC2652P: cc2652p design,

CC2652P: codec function and GPIO map for interface

Part Number: CC2652P
Other Parts Discussed in Thread: LAUNCHXL-CC1352P, CC3200AUDBOOST, SIMPLELINK-CC13X2-26X2-SDK

Hello 

 we want to know same informations for CC2652P:

1. Does CC2652 support codec function(ADC, DAC)  for analog audio signal?  If not,  what digital interface could be used for audio? Better to have a reference diagram. 
2. Is there a more detail pin map to show pin definition(not just GPIO XXX, but have detail information)?

    Hi,

    1- The CC2652P does have a DAC. You can review the section 5.15.2 of the datasheet of the device for further details. You can also the very good I2S module available on this device.

    2- One of the advantage of the CC26XX/CC13XX device family is the possibility to map pretty much any module on any pin. So we do not have a real pin map to share. Maybe you can review our evaluation board (in your case, I suggest to use LAUNCHXL-CC1352P and its quick start guide). As you will see the I2S signals are not mapped but it is definitely possible (I usually use IOID_25 (ADO),IOID_26 (ADI),IOID_27 (BCLK),IOID_23 (MCLK),IOID_16 (WCLK)).

    To finish, let me point you to the SimpleLink Audio Plugin developed by TI.

    Best regards,

    Hi Clément:

    Thanks for your replay. Could you help me on some extra issues? 

    1. Does CC2652P have a audio processing system to do jobs like mixing, gain adjusting?

    2. I checked SimpleLink and found a CC26X2 SDK, is this fit with CC2652P?

    Hi,

    1. CC2652P has a Cortex M4F ("F" for floating point unit). Depending on what kind of audio treatment, it might be enough. If your application is a bit MIPS hungry, I would suggest to use a dedicated audio codec, such as the TLV320AIC3254 (you can then review the CC3200AUDBOOST compatible with our launchpads).

    2- The SDK to use for the CC2652P device is this one: SIMPLELINK-CC13X2-26X2-SDK (compatible both with CC13X2 and CC26X2 devices). As you will see, there is no evaluation board (launchpad) for CC2652P, but you can use instead LAUNCHXL-CC1352P (see here for more details)

    Best regards,

    Hi Clément

    1. Can one CC2652P be the host device ,and connect two or more slave CC2652P? so we can use the host device to recieve the other two or more device's audio signal.

    2. In general, what the TX gain and RX sensotivity can be? dose it can reach +20dBm for TX and -105dBm for RX sensitivity?

    3. Is the DAC&ADC can used for codec? i see it's just 8bits DAC and 12bits ADC ,for normal audio is that too small, the normal codec are 16bits.

    Hi,

    1- Yes, TI's BLE stack provides the possibility to have several peripheral devices connected to the same central device.

    2- This information can be found in the data sheet.

    – Excellent receiver sensitivity:-100dBm for 802.15.4 (2.4 GHz),
                                                          -105dBmfor Bluetooth125-kbps(LE CodedPHY)

    – Output power up to +20 dBm with temperature compensation


    3- This is up to you, it depends on the audio quality you are expecting. But, as mentioned before, you can use other ways to sample/play audio such PDM (audio input only) and I2S (audio input and output)

    Regards,
