TinyLily / Custom bootloader for less 2.7 volt function
« on: January 10, 2017, 01:32:34 AM »
I'm working with a tinylily + 0,98 oled i2c display and a cr2032 battery...
When power go below 2.7v the tinylily stop to work but the display have enough power to display...
I remember to have read a line about the ability to change bootloader to have a working microcontroller working with less than 2.7v power batteries.
How to do that sort of work...
Is it a changing fuse values or other way.
Please help.

TinyLily / clock speed difference
« on: November 21, 2013, 05:47:21 PM »

i've bought couple of tinylily and upload same sketch in it, but it seems the second is half speed!
Have to divide delay() by 2 to have something at the same speed!
Is it possible?
Not sure that the tinylily are coming from the same invoice but are both "rev2"
Any idea?

the only difference is the programming module not the same (i've bought 2 basic kit)
