Converting a float into an int with greater than 11 bit exponent?
Hi All, This has probably been asked for in some shape or form. It's not a problem I've come across as I rarely do float maths, but the PID library I'm using is doing just that....

I2C library using INT for clock-stretched write?
Hi,   Just extracting myself out of Arduino where going through the code they use I realised they're looping to write to I2C.   I need to recreate the 2004 LCD library...

AtMega2560 -> Maximum ADC Frequency
I've an Arduino almost entirely reconfigured with the software as optimised as I can get it. Interrupts do little work, set flags and work is done in the loop.   There are...

ATtiny1616 -> Comparator Hysteresis Variance
I'm using a resistor divider, the fabulously low 0.55v reference, and "50mV" hysteresis to net a turn off and on point of the equivalent of 9.5v and 14.5v. It works very well...
