Yesterday I finished first version of firmware - it is able to measure voltage up to 20V, measure resistances from zero up to 5MOhm with 10Ohm resolution and calculate something else from those measurements using second order polynomial function. Coefficients of this function can be entered by user via joystick - I must tell you it is as inconvenient as I expected. On the other hand, floating point routines ate a lot of FLASH memory

115 words of FLASH remaining. There is a few details missing (indication of battery state), so I'm going to find good use for this bunch of memory cells. Oh yes and it seems like SDCC authors do like Frank Zappa

Sorry for such as short project log, but hackaday.io page doesn't allow me to post more without getting error 413 message. Meh.
