Another processor with NRF52

[Raja]

I have created a program on Arduino which does audio/video output and takes input from accelerometer and camera module. I was able to move accelerometer code to NRF52 with @martinbl e.g.

On other posts it was mentioned with softdevice running we might get problem with audio output. Also i was not able to create any e.g. with audio/video on NF52.

Now i was thinking of having another chip like avr or arm processor which can take commands from NRF52 via rx/tx and run audio/video etc. By this Nrf52 will only be responsible for BLE connection and other chip for processing commands.

Am i completely wrong or is this right way? If i am right can you please recommend any chip which is used commonly with NRF52 and is rx/tx best way to communicate with primary nrf52 chip?

Thanks

Well nRF52 has enough power and peripherals to run as single chip in most embedded systems. But it requires certain embedded SW and HW development skills to over come all challenges. You can indeed take opposite approach to just wire multiple of chips over SPI/I2C/UART and let each of them do more or less single function (sensor data gathering, radio communication, audio input, audio output...) In normal commercial product this would be probably unacceptable because of high BOM and manufacturing cost but for prototyping/small batch/hobbyists this approach is fine as well.

I won't advise you on what chips you can pair with nRF52 because basically everything what can do UART/SPI/I2C/I2S will work.

Thanks @endnode your points are very valid. It is a great forum and nordic is doing good job also skilled people like you also contribute a lot and i respect it. I use to develop on Arduino at start then realised i need to properly develop using industry standard hardware and tools. So i moved to Nordic chips as i need BLE for what i need to develop. They have great forum here with tutorials. So in past 3 months i have learned a lot. Now i can comfortably develop BLE services talking to my custom made apps on iOS and android. I have learned how to integrate different hardware components. For some i am still finding ways like for touch screen display/audio out/microphone etc. Also i was able to use open source tools in my journey here. I have been developing software professionally for last 20 years and have moved a lot between different technologies like server side, web, desktop, databases, big data and mobile this was only possible as in software side companies like microsoft, oracle, google apple spend lot of time writing tutorials for new developers to there platform so i would request nordic to take same approach and carry on there amazing works by adding new tutorials every 2 weeks and keep there existing tutorials upto date.
