9 years agoHello Kraz,
Thank you very much. The problem is solved! I double checked the first valid. At the first valid the channel and data are from c1 instead of c0. This is because the counter setup, which I use to generate channel number and select data, was set to [<_initial_value> <_modulo> <_step_size>]= [0 5 1], and the output became 1 at the first valid. Instead I have to set it to [-1 5 1] to get the first channel number to 0 at the first valid. Once I did this everything looks nice! Thanks a lot. Tormour
