one of my projects needs a support of MIPI protocol, in order to send camera sensor output via WiFi / BLE. The sensor output should be 1 picture at several minutes… so the stream speed does not important.
I was thinking to use the BW16 (RTL8720DM) module, but I saw that there is not enough GPIOs to direct connection to a parallel sensor, so, I have to use a serial sensor - probably a MIPI sensor.
Does the RTL8720DM can support the very fast MIPI protocol? should I use a parallel to serial (shift register) chip in order to read a stills picture from the sensor?
Thanks in advance!
Hi @Evyatar_Nassie ,
No MIPI as far as I know, but according to the demand you described, there can be other options besides MIPI, unless MIPI is a must in your project
As I understand it, the RTL8720DN does not have on-silicon support for the MIPI CSI interface. You might want to consider other methods, such as this Arducam camera which uses a FPGA to convert the parallel camera format to SPI.
Thank you very much!
even the recommended sensor is very expensive, I may use it, since I don’t know any other serial camera sensor…

Thank you very much…
I should look for other solutions as you suggested…, but looking for a serial camera sensor (I2C / SPI) is probably not a simple mission…

@Evyatar_Nassie Do check out this camera that wyy pointed out, it works very well with SPI
thanks I’m on it right now…
