I'm a programmer that's a little out of his element here, and not sure where to start.
I'm trying to figure out a way I can connect this TTL camera to a PCB that also has a cheap ARM or DSP CPU on it. The ARM would be running some kind of headless Linux (probably Debian) with a homegrown device driver (I'd have to write it myself) that could read the serial video bitstream from the camera and do something with it.
So my constraints:
- Cheap ARM/DSP processor that can run Linux
- The camera (linked above)
- Custom device driver (unless the camera comes with drivers, which the link doesn't indicate)
- I'd prefer to spend less than $100 on the entire solution (camera, chip, board, etc.) --> cheap
Everywhere I look for an ARM chip, I get one of the following:
- I have to buy in bulk (not an option; this is a hobby project); or
- I have to buy a full MCU/SoC with lots of excess stuff that I don't need/want
Do I have any options here? I've been reading up on custom/DIY PCBs using this "toner transfer method" and it seems interesting. If it's possible, I'd be happy to design my own circuit, make my own PCB, and then attach a cheap standalone ARM chip to it (as well as the camera and anything else). But perhaps that's not an option; perhaps attaching a CPU to a homemade PCB isn't feasible for technical reasons.
My first preference would be to find a cheap CPU, solder it to my own homemade PCB, and do the same with the camera. Is this possible? If not, perhaps someone could explain why, and tell me what my options are?
Either way, I'm not real familiar with ARM. What's a good make/model that would suit my purposes? Thanks in advance.
