As I have mentioned in last blog. There have been new challenges to me. With thorough I have got new solution and new parts to make it work.
1. Solution to heavier motor
I have to add a new worm reducer which can change the rotary direction in 90 degree, in comparing with my previous simple design with the axis of motor a turn shaft. A coupling part shall be prepared to link the motor and the reducer. I will post photos later when I calibrate the mechanical parts.
2. As to direction controlling, heavy parts are not fit for precise gyro-sensor data-sampling. I have ruled out the possibility of simple Hall-effect on/off switch. New FDC2114 chip by TI is Noise-immune Capacitive Sensing Solution for Proximity Sensing, by I2C porting, it can reflect the distance of Proximity. The problem is that I have to design a small PCB and soldering the parts. Furtunately, fress sample policy by TI has saved my time and one FDC 2114 is in my stock now. I will design with CADstar by Zuken. The scheme and PCB design will be uploaded in next blog.
3. While new problem baffle me, the incompatible of KDS with KMS. The sample project in Kinetic Motor Suite can not pass Build process in KDS 3.2.0. Some dependency seems missing for some library. That is huge work if I have to find out what happens. With two weeks of program code search, I have decided to program from a blank project. I have noticed that there is not much updated blog recently. Maybe they have met same problem as me. My suggestion is try to program by my own. It will cost time to program but save time to debug.
I have found a drawing for this Linix motor a attached. There are some Chinese words in the drawing. I try to translate it in English and shown in this screenshot.
