ICS43434

Open bulbitron opened this issue 9 months ago • 1 comments

Hello! I was testing your program with an INMP441 that has characteristics similar to ICS43432 and works correctly, but with an ICS43434 I have not been able to make it work, I only get 00 00 00... by serial realterm, looking at the 43434 datasheet I saw that some parameters differ of the previous microphones but my knowledge is not enough to adapt your program,if it is still something simple for you to indicate the solution, In the datasheet of the 43432 we find SCK frequency (fSCK) 0.460 to 3.379 MHz but in the 43434 we find 6.25 to 18.75 kHz, it would be like 0.007 Mhz, how could we adapt this? Thank you very much for your work

Sorry, everything works correctly, I am using a raytaq module that has some pins that are not recommended for high frequencies and the problem was that, changing the pins everything is correct, fantastic program, a similar one for PDM would be great
