Tit

Description

Ever wanted to have two hardware Serial Ports, two SPI, two I2C and more PWM pins on the Arduino Pro Mini? Tit has all of this, and retains the same form factor. Tit uses Atmega328PB at its core.

Tit, is pin compatible with Arduino Pro Mini, the chip Atmega328pb is software compatible with Atmega328p. Hence all the existing code and libraries should work without any changes. Tit uses higher version of avr-gcc toolchain, we have bundled it up as a package along with additional libraries required to access the extra features.

Check this detailed tutorial on setting up Tit for different operating systems.

Help! Want to change the name from Tit to Bee, what do you think?

I am found of naming boards after birds. Tit was named after the bird Willow Tit. Since I am not a native English speaker was not aware of the other meaning of the word Tit/Tits. Speaking to a friend, I realized what it means. I had done a google image search for the name, when finalizing it. Nothing else except the bird had popped up in the search results, because the search filters were on! Apologies for it.
I think I will rename it to Bee (after hummingbird bee); will have to change all the references in code, pages and even the name on the board. We have 100 PCBs made for it. Will putting a sticker help? What do you think about the whole thing?
PWM channels on Tit

Did a test on all PWM channels! The code can be found on the tutorial page:

Tool-chain tests on windows and linux

The current Arduino toolchin (AVRGCC etc) does not support the new chip hence it was required to update it. However instead of updating the existing toolchain, we decided to use the new tool chain just for the board. The platform allows inclusion of tool-chain for a specific board. Picture below shows the setup that works on windows.
Similarly we did tests on Ubuntu 64 bit. We believe it would work on other linuxy/unixy machines.

The detailed steps can be found on the tutorial below.

We would need your help in testing this on other unix/linux machines and see if works. Also testing it on other versions of Arduino Software will be of great help. Please do comment if you've any concerns.
