Using the dual slope method a resistor value can be converted into a digital counter value To do this the charging time of capacitor C18 will be measured with the 16 Bit Timer Event Counter 00 of the microcontroller The first charging slope will use a reference resistor RREF R6 and the second charging slope will use variable resistor RvaR R5 RT which should be determined By the comparison of the two measured times and the known reference resistor RREF the variable resistor can be calculated The 78K0 LX2 device family has the advantage of bit settable I O ports and Schmitt trigger inputs e g timer input port 11000 The L_Line See it board uses the bit settable port PO as a bidirectional port At first the complete port PO is cleared and set to output mode In this case the capacitor C18 is discharged via P00 11000 and prepared for the first measurement The resistor R7 is only used to limit the current during the discharging of the capacitor Then port P02 is set to 1 and output At this point also the 16 bit Timer Event Counter 00 is started The rest of the port PO is set to input high impedance So the capacitor will be charged via the reference resistor Re When the capacitor has reached the threshold level of the Schmitt trigger input POO TIOOO the actual timer value is automatically captured and an internal interrupt is generated Using this interrupt the capture value is read out In the next step the capacitor C18 will be di
