DSP I2S
Posted: Mon Aug 29, 2022 1:30 am
Hi Ben
I have already used some of your your DSP functions before using EB085 & EB086 using DSPIC
But now looking at practicality of carrying out some DSP manipulations this time using input from a codec chip using i2s
Need to sample 2 analogue inputs 24bits sampling each around 300khz and then performing some DSP filtering and FFT processing
1 Is this practical speedwise using the flowcode I2S component and the DSP functions with a ESP32 within flowcode
2 I also notice that the only i2s component that is currently available appears to be for ESP32 is it practical to use a DSPIC33 instead as i have more experience using this chip
3 There are a number of stereo codec a/d chips around which appear to use i2s any suggestions which have been successfully used in existing flowcode programs
4 Are there any basic examples you can forward me which i can use as a start
Best Regards
David
