Simple fix hopefully. Keil M3

i need to edit this code so that im not using ADC, and instead some instruction that is allowed, listed below.

i got the Warning below when i replaced ADC with ADD. It caused me to get a different result.

The result im looking for is for R1 to be E. Depicted in the last picture here. thanks

good answer = thumbs up!

MOV r1, #0 ;r1 = 0

MOV r2,r0 ; r2 = r0

MOV r4, #0 ; r4 = 0

countone ; loop

MOVS r2, r2, LSR #1

ADC r1,r1, r4 ; r1 = r1 + r4

CMP r2, #0 ; compare r2 and 0

BNE countone ; branch if not equal to loop

stop B stop

END
