Hi all,
My name is Patrick. This is my first time in this forum.
I ve just bought a PIC 16F877. Wow, so exciting, and I wanted to build my own first application. Well, I dont know if it is feasible or not, because I am a newbie in this field!
Ok, this is the specification:
This timer is for marital arts, which allows me to select number of rounds, duration of round, and break time. Current time will be shown on a LCD. So I reckond, the max period of time should be around 5 mins. There are 3 buttons, which are stop, reset and start.
I have few questions about this application. Could you please help me out?
1. There are many timers inside the chip such as TMR0,1,2,3 and even Watchdog timer. I dont know which one to use. If the max time is 5 mins, I think I can use Timer ) with 8 bit input.
2. I get an idea to use the crystal, but if so, I wont use teh CHIP I like make use of the chip.
3. How can I implement the button?
Thanks
Have a good day
Patrick
