====== RTCRead( ) ======

''variable = RTCRead( address )''
| //variable// |variable to store the result (Byte type) |
| //address// |RTC’s address |

If you see the address table of RTC chip (DS3231) below, you will notice
that the time data are stored from addresses 0 through 6. The rest of the
addresses are related to the alarm and RTC chipsetting; thus, we
recommend those interested to refer to the DS3231 databook.

RTCRead command literally reads data from the RTC chip.

To use CB405RT, in the beginning of the program, one must replace Const
Device = CB405 with #Include "CB405RT".


<code xbasic>
#include "CB405RT"          ' Use "#include" instead of the "Const Device" statement.
Dim i As Integer
Wait 100
RTCwrite 0,&h20             ' Sec
RTCwrite 1,&h59             ' Min
RTCwrite 2,&h23             ' Hour 24h
RTCwrite 3,&h7              ' day 1-7, 1=Sun, 2=Mon, 3=Tue, 4=Wed, 5=Thu, 6=FRI, 7=SAT
RTCwrite 4,&h31             ' Date
RTCwrite 5,&h12             ' Month
RTCwrite 6,&h08             ' Year

Do
 i = RTCread(0)
 Debug Goxy,1,1,Hex2 i, " Sec"
 i = RTCread(1)
 Debug Goxy,1,2,Hex2 i, " Min"
 i = RTCread(2) And &h3f
 Debug Goxy,1,3,Hex2 i, " Hour"
 i = RTCread(3)
 Debug Goxy,1,4,Hex2 i, " Day"
 i = RTCread(4)
 Debug Goxy,1,5,Hex2 i, " Date"
 i = RTCread(5)
 Debug Goxy,1,6,Hex2 i, " Month"
 i = RTCread(6)
 Debug Goxy,1,7,Hex2 i, " Year"
 Wait 500
Loop

will appear
