I am working on a project similar to your standard digital clock. From what I have been reading it sounds like the best way to make an internal RTC with a PIC16LF88 is by using timer1 or timer2. It also sounds like to get a descent accuracy I am going to want to use an external crystal as opposed to the internal RC clock. If I did use the internal RC clock, can anyone estimate how many minutes I would lose a day or month, assuming my code was correct?
My primary concern for this clock is for it to have a low power consumption. I have been reading about the "RC_RUN" and "SEC_RUN" features of the 16F88...still working on fully understanding those. If anyone has any good sources to complement the datasheet, it would be helpful. If not, I can probably figure it out.
I would like to power the entire project from a 3V source. I was originally going to use a 2 line LCD display for the output, but as far as I know they only come in 5V versions. Does anyone know of a good low-power display that can run off of 3V?
I am going to have the display off until the user presses a button, where it will come on for 30 seconds. I am planning on powering the display directly from a pin on the chip. According to the datasheet the 16F88 can source a maximum of 25mA on an I/O pin, so it should handle any display I use. Anyone disagree? (Keep in mind, it will be a low-powered display)
The plan is for this to be used in outdoor conditions, any suggestions on waterproofing?
