Hi all,
Just getting into the world of Picaxe with a project...
I am attempting to automate several tasks, including the control of a few relays and solonoids. These components need to be operated at set times throughout the day, for various durations. I wish to be able to adjust the timing intervals and duration through the use of several dials, and display the current system settings to an LCD. From the research i've done it appears the easiest way to do this would be through the use of the AXE033 LCD and 034 timing modules, using the alarm out signal as an input to my Picaxe chip.
My questions are:
Are these modules appropriate for my needs?
When interfacing the modules using ic2 to a standard Picaxe, will I be able to not only read the time value and display it to the LCD, but also display other variables on the first LCD line? From what I gather the data flow is as follows:
RTC -----i2c----> Picaxe -----> LCD
Is this correct? Will I need a specific model Picaxe or do all models have i2c input capability? From the axe manual the Pic 08 series chips do not support i2c?
Can the alarm time be set at runtime using the interfaced Picaxe chip, allowing me to control when the alarm will activate without the need for reprogramming? The documentation says this would be done through the use of a serial out with writecode 8 or 9, ie.
serout 7,N2400, (253,8,”00/00/00 07:30 ”
Sorry if these questions seem rather obvious.
