RGB Sensor with ATtiny 25

Post by Samuelma »

Hi Folks, I'm looking for some pointers with utilising the TCS3472 RGB sensor with a smaller chip than the arduino or its 328.

I'm pretty confident i could get some code together to get the project im working in done using an uno board or the breadboard -dunio im prototyping with at the minute but i'm not hugely knowledgeable in AVRs and microcontroller, can anyone help with wiring them? and/or any resources for this ?


Thanks a lot :)

Sam

The ATtiny25 is pretty limited, but our Trinket uses its big sister the ATtiny85: https://www.adafruit.com/products/1500 If nothing else, you can use the design of that as a reference for how to wire the support hardware.

If you decide to stick with the '25, you'll probably need in in-circuit programmer. There are dozens of them out there, incuding Atmel's AVRISP mkII and our USBtinyISP: https://www.adafruit.com/product/46

The peripheral set for the '25 is the same as for the '85 (same timers, ADC, PWM, etc), so code that runs on a Trinket should port to a '25 as long as its RAM and Flash footprints are small enough.

Thanks for the reply, its a lot of help :) tempted to just build it off the trinket for now at least, seems a great little board. Thanks :)
