Hello SDCC : stm8 3.4.1 #9068 (Sep 5 2014) (Linux)
I dont see the difference between this ( A and B ) : I have _lcdchar declared by : .area OSEG _varOne: .ds 1 _lcdchar: .db 1 .area CSEG . .which seems not working, at least the way variables are to mee in assembly ... . A) ;try write I ### this block doesnt work: prints "trash" ldw x, #0d05 call delay_m mov _lcdchar, #0b01001001 ld a,_lcdchar ; "I" upper "i" : ascii code in the hd44780 and a,#0b11110000 ; delete lower nib or a,#0b00000011 ; put in that : data write + bkl ON ld PD_ODR, a ; #0b01000011 bset PD_ODR, #3 bres PD_ODR, #3 ldw x, #0d5 call delay_m ld a,_lcdchar ; "I" upper "i" : ascii code in the hd44780 swap a and a,#0b11110000 ; delete lower nib or a,#0b00000011 ; put in that : data write + bkl ON ld PD_ODR, a bset PD_ODR, #3 bres PD_ODR, #3 And that: B) ;try write I ### this block writes a capital i . ldw x, #0d05 call delay_m ld a,#0b01001001 ; "I" upper "i" : ascii code in the hd44780 and a,#0b11110000 ; delete lower nib or a,#0b00000011 ; put in that : data write + bkl ON ld PD_ODR, a ; #0b01000011 bset PD_ODR, #3 bres PD_ODR, #3 ldw x, #0d5 call delay_m ld a,#0b01001001 ; "I" upper "i" : ascii code in the hd44780 swap a and a,#0b11110000 ; delete lower nib or a,#0b00000011 ; put in that : data write + bkl ON ld PD_ODR, a bset PD_ODR, #3 bres PD_ODR, #3 thnx again for stm8 support ! :) ------------------------------------------------------------------------------ Slashdot TV.
