warning: comparison is always false due to limited range of data type

[Jorgen Birkler]

E.g. gainEE is declared int8_t so it cannot hold values more than 127.

Also, the expression inside doesn't make sense: KtaRoCo = KtaRoCo - 256; will do nothing, since KtaRoCo is only 8 bits wide. Same goes for all the others. Did you mean to invert the value? KtaRoCo = 256 - KtaRoCo;
Since KtaRoCo (and others) are signed, you can just do if (KtaRoCo < 0)
