Description:- This program uses TMR0 to generate a 100mSec delay using interrupts. A pushbutton (PB0), connected to pin RA0 of the PIC16F188, is used start a mSec timer (i.e. a variable that is incremented every 100mSec ) whose value is displayed on an LCD screen. Another pushbutton (PB1) is used to reset the mSec timer. LED0 is used to indicate that the mSec timer is running (i.e. incrementing) while LED1 toggles on/off every 100mSec from within the interrupt service routine (ISR). *See LAB_7B_TMR0_INT_Delay_100mSec for details of a very similar program \[ \begin{array}{l} \text { Tdelay }(8 \text { bit Timer })=\text { Tosc } * 4 * N *(256-\text { TMR0_Init }) * \text { count } \\ \text { Tosc }=\frac{1}{\text { Fosc }}=\frac{1}{19.6608 \mathrm{e} 06} \\ \text { Tdelay }=\frac{1}{19.6608 \mathrm{e} 06} * 4 * 256 *(256-16) * 8=0.1 \mathrm{Sec} \end{array} \] Description:- This program uses TMR0 to generate a 100mSec delay using interrupts.
