here's my code:

Code: Select all
dim position as integer
dim position1 as integer
dim position2 as string[20]
dim position3 as string[20]
dim thechannel as integer
dim thechannel2 as string[3]
thechannel=0
position=5000
position1=position>>6
inttostr(position,position3)
inttostr(position1,position2)
do
inttostr(thechannel,thechannel2)
uart1_write_text("0b11100000 |")
uart1_write_text(thechannel2)
uart1_write_text(position2)
uart1_write_text("0b01111111")
uart1_write_text(position3)
uart1_write_text("0b00111111")
uart1_write_text("50")
inc(thechannel)
loop until thechannel=7


no response = doesnt work. anyone can exlain why? by the way, i dislayed the position3, position2 and thechannel2 on lcd, and here's what i got:-

position3 = 5000
position2 = 78
thechannel2 = 50

anything wrong with my code?

i think the error u mentioned come from the GUI software. maybe the visual studion version incompatible? mayb u can try to recompile the GUI. or mayb u can send packet through terminal software like XCTU to test?
thanks&regards,

Hi, i never use mikrobasic before therefore i not really understand on your code. Maybe you should put some comment on your code so that ppl can easily understand the coding. Just to remind you that you need to activate the servo channel on SC08A everytime SC08A is power up. I checked on the SC08A's UM, you will need to send two bytes of command to activate the servo channel so that the servo will respond to you at position and speed command.

i just modified the code from cytron arduino tutorial to mikrobasic language style. n currently, the windows app provided by cytron cant control the board too. is this mean that my sc08a is not functioning well?

Since it is working with the test button, i don't think is the SC08A problem. Maybe you can try to use Arduino to test on it first. :lol:
