Serial Streaming

Serial Streaming

Not very happy with the performance I get from Processing in displaying the images coming from my Arduino Module I decided to build a dedicated application to “see” the image instead. Is part of a bigger project, my “stereoscopic vision” project ^_^ Kind of a long shot, but sounds like a lot of fun. Anyway, I … Continue reading

Tuning…

Tuning…

Last night managed to spend some time to redo my panning code and got it moving much better. Still work to be done but is not too bad. Then got a CF7670C-V1 module work with this setup, also tracking at high-speed using the same piece of code, by doing a short-circuit between pin5 and pin6 … Continue reading

“Arduino camera” and mbed

“Arduino camera” and mbed

So far the tests to attach the OV7670 camera to a robotic platform seems to work. My “arduino camera” module (not sure how to call it since “AVRCam” and “ArduCam” are already used by other public projects) seems to work pretty fine  attached to a small tracked robot, same base with the one I’ve use … Continue reading

Going faster

Going faster

Looks really interesting… Using CF7670C-V2 module I can go faster on my board… Is what I see is correct can basically track one color at 30 FPS… The movement looks so smooth on the Processing screen I use for displaying the data in real-time. The good part: is a way to make a V1 module work … Continue reading

CF7670C vs CF7670C-V2

CF7670C vs CF7670C-V2

Managed to get a CF7670C-V2 module in the end, and the available schematic only shows that WRST was replaced by HREF, which is a bit of nonsense, cause in that diagram WRST was left floating. I connected the module and all you see is noise…. Digging further, managed to find the real schematic then all … Continue reading

Assembling the parts

Assembling the parts

By default, OV7670 module come with pine header at 90 degrees while I need straight ones, so I had to take the original one out and replace with straight ones: I attached the module to a Lynxmotion bracket using a scrap of thin PCB drilled and a bunch of small screws and spacers and replace … Continue reading

AVR/Arduino Camera v0.3

AVR/Arduino Camera v0.3

Due some hardware glitches, no holes to attach it to my servo bracket or to anything in general, I had to build a new version. Anyway, took the decision to drop the testing connector (the 5 pins header on the second board pictured bellow) and now, instead of reading last 3 bits of every half byte … Continue reading
