Today I would like to present you with the latest firmware changes for AMC. The difference is so big that I thought it makes a nice piece for the news page.
I was hopping to fix the really noisy ADC function for several years, and I finally got it. Now it follows closely the potentiometer and the measurements are not affected by motor power noise or other parasitic noise from environment.
To achieve that noise reduction I made my own routine to access directly the ADC registers and handle their sampling timing with a interrupt. This gave me a great deal of freedom to make the sampling time of each channel as fast as 7us (microseconds) or 0.000007sec. Just for comparison, before was 250us using standard library code.
This allowed me to also increase the program cycle speed up to 9000 times (when not receiving), and up to 7000 times per second when receiving data from the computer.
See the comparison video and the timing diagrams below:

You can test a simulator without owning the fitting hardware. You can follow our traning tutorial to get into the software by using a simulated simulator addon. You will find this 3D simulators in your installation folder and you can execute them if the extractor and the converter is running. It is possible to setup your games and fine tune the simulator output with this tools. If you adapt your hardware later you can use the same profile. This is extremly worthful if you build your hardware and like to get into the software at the same time.
