In the following macro statement for tiny-0 & tiny-1 TWI baud rate register value, there is a "\" floating out at the end of the first line.
#define TWI0_BAUD(F_SCL, T_RISE) \ ((((((float)20000000.0 / (float)F_SCL)) - 10 - ((float)20000000.0 * T_RISE / 1000000))) / 2)
Does it have a purpose or a function or is it ignored?
Code is from Dieter Reinhardt library included at the end of Msg #1 in https://www.avrfreaks.net/forum/...
Have looked for the original source, but google-fu has failed me.
