	RC SERVO CONTROL VIA TPU
by Jeff Loeliger Start ı The Answer Isı ı Designing Functions ı Demonstration ı Youıre in Control ı Sources and PDF YOUıRE IN CONTROL From the information given, it is obvious that the TPU is an extremely efficient way of controlling servos without causing any additional loading to the CPU. The entire servo function described here is implemented with only 23 TPU instructions and a single channel running the function only loads the TPU3 by less than 0.175% when running at 40 MHz. The minuscule loading requirement placed on the TPU leaves the door open for enhancements such as a 10-bit version of the function or an option for higher resolution. The future of the powerful TPU is limited only by the imagination of the programmer. PREVIOUS • NEXT Circuit Cellar provides up-to-date information for engineers.
