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.

And one more: I hope Nordic support team will appreciate your feedback on lack of tutorials (which I personally would argue a lot because you have TONS of tutorials and examples for nRF5x) but I believe you understand what's happening here: Nordic isn't non-profit organization which releases low-cost boards for DIY/hobbyists/teaching of kids (which Arduino more or less is), it's publicly listed private business which wants to sell as much chips as possible. Who is then main focus? Big OEMs and similar companies embedding low-power radio chips to all different electronic devices and pushing hundreds of thousands of them to the market every year. These guys have teams which don't work on Arduino IDE level, they are embedded SW and HW professionals. So you need to understand that while Nordic is so nice and kind to support everyone on this forum, the main focus of all the support materials
