I believe you need to treat the data as Binary Coded Decimal, However if you enter the data as 2 digits of hexadecimal that should work. Just don't enter any alpha digits, ie. ABCDE or F. Try replacing the lines:

SERIN2 RX, Baudrate, [DEC2 TEMP] with SERIN2 RX, Baudrate, [HEX2 TEMP]

and

SHIFTOUT DG, CLK, 0, [$30] ' Send hours with SHIFTOUT DG, CLK, 0, [HEX2 TEMP] ' Send hours

[richard]

SHIFTOUT DG, CLK, 0, [HEX2 TEMP] ' Send hours

will not work

the value needed to be sent is a packed bcd byte not two hex chrs
consideration also of the 12/24 hour bit must be considered also


simple way to convert binary hour value in tmp to packed bcd in hour

HOUR = ((tmp / 10) << 4) + (tmp // 10) ; bin to bcd
