Hay dos problemas: primero, las líneas \"high = i - 1\" y \"high = i\" en ocv2cap tienen el orden incorrecto en comparación con temp2resist. Como consecuencia, ocv2cap establece high=-1 si ocv>table[0].ocv, lo que provoca una lectura fuera de los límites. Segundo, la lógica de temp2resist tampoco es correcta. Considere el caso table[] = {{20, 100}, {10, 80}, {0, 60}}. Para temp=5, esperamos una resistencia del 70 % por interpolación.
