| Purpose: |
Place an ASCII space ' ' (32 = 0x20) and one other printable
character into the COM1 the Transmit Buffer.
The routines' names indicate the order of the characer output. |
| Assumes: |
Nothing. |
| Passed: |
R24 CHAR cValue
the character to print, 7 to 254. |
| Returns: |
Nothing. |
| Alters: |
R24, the FLAGs (SREG), and the COM1 Transmit buffer |
| Example: |
.ORG 0x1000
PrintSNDigits:
LDI R30, 14 ; Loop initializer
MOV R31, R26 ; Command line tail pointer (NULL or not)
Loop:
MOV R24, R30 ; Specify which Signature BYTE to read and
INC R30 ; pre-advance it to the next one
CALL AReadSignatureBYTE
CPSE R31, R1 ; See which print path to take - if there was
RJMP ACharacterMode ; ANY command line tail, do alternate logic
CALL APrint0xHexBYTE ; Print the value returned in "0x##" format
CPI R30, 24 ; If it has already printed the last one
BRSH APrintSND_Finish ; desired, exit the loop
LDI R24, ',' ; Specify the character to print, then jump to
CALL APrint1CHARAnd1Space ; output the 2 chars and return to our caller
RJMP ALoop
CharacterMode:
CALL APrint1SpaceAnd1CHAR ; Print the CHARACTER rather than HEX
SBRS R24, 7 ; Exit if the Signature BYTE's MSBit is set
RJMP ALoop
PrintSND_Finish:
JMP APrintNewLine |
| Test it: |
m>@ 4096 ; Unique MCU Serial Number:
0x55, 0x34, 0x37, 0x31, 0x35, 0x30, 0xFF, 0x11, 0x26, 0x25
m>@ 4096 ; Anything, really
U 4 7 1 5 0
m>

| Notes: |
Both of these routines utilize the PrintCHAR
and PrintSpace System Functions. |
|
"Printable" means a character with a value between 7 to 254, inclusive.
(see PrintCHAR for details.) |
