i’m replying from an email client but I lost the original and most of my replies using Chrome and directly access the group through it. I thought it might not present well but I actually highlighted with the client. If you’ll tell me what I should use instead I will start using it for future posts. I want to make them as easy to read as possible.
I left all the declarations off but mentioned they are declared as unsigned int or int. Yes, this version likely does have some redundancy with samples_in_pulse. It is a work in progress that wasn’t making much progress because of this weird problem. It appears now that the names start_of_pulse and end_of_pulse were the problem for some reason. I changed them to PulseStart and PulseEnd and the PRU responds now. I have no idea what the problem with those names is.
