Hi I'm using ADS1278 for converting voice with 8k samples please give me suggestions for to compressing and decompression technique for the audio C code. i referred the example code but its not working.
thank you.
Regard,
Suguresh M
Hello Suguresh,
TI does not have any example code for the ADS1278, other than the source code included with the EVM software. I believe the code you refer to is from a third party, and we are not able to support questions for these examples.
If you have problems communicating with the ADS1278, please include a picture of the waveforms, including SCLK, DRDY, DOUT, similar to Figure 1 in the datasheet, and a picture of the ADS1278 schematic showing the state of the IO pin configuration.

Precision ADC Applications
Hi Suguresh,
To add to what Keith has said, if you are using this for an audio application you may actually prefer to use a part like the PCM4204 unless you really need the DC precision or higher channel count of the ADS1278. Our audio converters will also have I2S/TDM interface if that simplifies your design.
Best,

hi keith i got it from TI only to how to compress and decompress audio from msp so i followed those steps and fro the zak point of view we selected wrong ADC for audio conversion.

Actually what we are doing is just taking the input from the mic converting to digital for that i used adc1278 Actually its converting the data but its not giving proper output i think its because of noise and its just normal functioning adc so because of that i didnt got proper output.
thank you,
