I stuck with reading images from a5020e optical mouse sensor using my new arduino due. :smiling_imp:
I studied the example here http://frenki.net/2013/12/convert-optical-mouse-into-arduino-web-camera/
The spec for the sensor available here http://pdf.datasheetarchive.com/indexerfiles/Datasheets-IS5/DSA0093762.pdf
When using example, I've got all zeroes at serial output.
I found that DUE uses SPI in different way than other arduino's. According to chip spec, there is ground, +5V, chip select, serial clock and...Serial Port Data Input and Output
But SPI neds MISO & MOSI. For 3 wires implementation chip select is skipped.
So, should I connect my MOSI and MISO (http://arduino.cc/en/Reference/SPI) ?
From the example above, I also doubt about pins 5-7. These are not standard SPI pins for anyone of arduino's. But As I learnt, when using not SPI pins, the communication speed drops dramatically.
Sorry for probably stupid question, I have my arduino just 3 days. Simple LED and buttons works well, but this stuff not yet. Thank, and have a great day!
