Hi Team,

Can anybody please see what im doing wrong.
if you enter a baselenth of 1m press enter.
Then select velocity of 1000m/s then press enter. then press fire it should generate a 1ms start stop time/

Thanks

Hello Wayne

Can you tell us what you are getting as pulse duration ?

Do you test it in "real" life or is it a simulation ?

Hi,
The simulation seems to work but not when programmed in to the pic and using a oscilloscope both the start and the stop happen at the same time.

Thanks

Hi,
The simulation seems to work but not when programmed in to the pic and using a oscilloscope both the start and the stop happen at the same time.

On both simulation and real hardware, both stop and start will occur at the same time.
The reason it happens is because just before stop_flag decision icon, you have port c set at 1 since this is masked it will only affect bit 0.
then if stop_flag = 1 then you have got port c1 set at 2, this is also masked, so will not change the state of bit0 to 0 so both C0 and C1 will be at logic 1
For each shot count, do you want start led to go form on to off, then when goes off you want the stop led to go on for a brief time, then back off etc?
If you can explain step by step what events you want to occur e.g. Start led on, after 1ms start led off , stop led on for 500 us etc.
Then debugging will be easier.
In the mean time, see if this one is any better. Not tested on hardware.
