OK ... i am serious here, please provide me with advice whether my assembly works for serial communication. It is basically a calculation on getting ampere hour. Here is the main part:
And here is the assembly to display this value to the 16x2 LCD:
Now I try to send Show_AmpHours as a serial data to my RF module.
The RF module is using a BR of 9600, 8N1 setting.
And here is my attempt to send it in assembly. Please, I am a truely newbie on assembly.
I am using 16F88.
I refer this code from other site and modify it a bit. Might want to know is the code correct?
Thanks, i really appreciate ur help.
Code:
calc_Ah:
add1632 Amps,AmpSum ; AmpSum = accumulated Amps
mov32 AmpSum,dd
movi16 3600*3,aa ; 3 reads per second, 3600 seconds per hour
call Div32 ; AmpHours = AmpSum / (reads per hour)
store_Ah:
mov16 dd+2,AmpHours
Code:
Show_AmpHours:
mov16 AmpHours,Number
call bin2dec
movlw ' '
call Print_Char
call ShowDec2 ; display "xx.xx"
movlw 'A'
call Print_Char
movlw 'h'
call Print_Char
return
Code:
call Show_AmpHours ; "9999.9W 99.99Ah"Now I try to send Show_AmpHours as a serial data to my RF module.
