Hi all,
I've ordered a couple of Teensy 3.0 for a project where I'm putting various things in an R/C car. I've got an NRF24L01+ module in it and a camera so I can do FPV.
It hit me that the teensy might be powerful enough to transmit a lo-res video stream over the NRF24L01+ module that's comparable to the (crappy) PAL signal I currently get.
I was thinking something like the OV2640 module in a low-res mode with JPEG compression enabled and then transmit it to a PC via another Teensy.
It seems that in order to get data from an OV2640 or similar module, it's necessary to clock it and then receive data on a parallel 8-bit bus. I was wondering if any of the features of the chip could help with this or if I have to do pure bit banging.
The NRF24L01+ supports up to 2Mbit and has an SPI interface. any ideas of high high a data rate I could sustain? I see that it's possible to use DMA for SPI transfers, so it seems to me that the limiting factor is the digital sample rate of the Teensy - anyone who knows how fast that is?
Thanks in advance.
