Hello, my name's Jorge, I am an electronics engineer with experience developing firmware for embedded devices.
I have read the document with the timing specification of your project, I have a couple of questions related a couple of bytes, but these are minor details. In particular, I can complete your project, but for this type of projects I ask for a development board for testing with my oscilloscopes and equipment, do you think you can provide that? or do you want someone to work 100% remotely?
Please contact me to discuss this and other specifics of your project, I'd like to talk to you so we can start working on your project as soon as possible.
Thanks for your time.
