Good evening
Thank you for your replies.
i am currently talking to a 20 years old Spectrofluorometer... I must adapt it in order to use the device with a new computer. So we are using an Arduino to achieve this goal.
But, as Pylon told, 8 Khz is a very low frequency and I doubt I can reach it since I only could get a minimum of 30 KHz frequency.
I also have been able to send data with a homemade clock (including delays..). The Saleae device understands the data and so does the spectrofluorometer : small variations semm not to matter so Pylon and Riva are right.
However, sending data may turn out to be complex.
If we could change the SCL frequency using TWBR then we would be able to use the Wire library. This would simplify our problem.
I will post codes and screenshots as soon as possible.
Thanks
