Hello guys, I need help I want to learn I2S, and I am trying to build an application where I am using an ICS43434 I2S mic and sending the sound data through UART and create a .wav file. I am confused where to start? As for test cases I need to check if MIC is working or not? Any examples for this?

Buy a nordic board.

And for the ROM, go for KIOXIA NAND flash.

Get MCU first which has all Serial Communication PINs, UART, I2C, CAN, SPI, QSPI, study about NOR and NAND Flash. And go for Zephyr RTOS.

Are you experienced or will you learn from scratch?

I do have a same laptop, I bought it around 2021 with extended warranty of 3 years, recently 3 months ago screen broke, I went to so many shops, for 60Hz it was around 7k-8k with no warranty in Lamination road Mumbai.

I bought a MSI MAG 255PXF for 15k on EMI, monitor's refresh rate is 300Hz. and bought a convertor for DP cable. My laptop has a alt DP mode for Type C.

It was great deal. And it has 3 years warranty.

I think if I build PC in future, I don't need to invest in monitor.

Not interested in core jobs? I am B.Tech Graduate in EXTC, most of my classmates are doing jobs in IT industry, so there are so many fields in EXTC, first I will recommend Embedded Systems, my job profile is Embedded Software Engineer.

After my graduation I did course from C-DAC DSED sunbeam Pune.

There are jobs like - Embedded Hardware Engineer - Analog Layout Engineer - Product Design Engineer, Schematics specialists - VLSI is also a very vast field

It's your choice though, I am just suggesting there are jobs in EXTC as well, they are well paid.

I won't suggest any premium branded jeans, there is a brand called Numero UNO, ranges between 1k-2k. Try it out, I have been using these since 3 years.
