Sampling design of ePWM triggered ADC based on 28035
preface
Jiudao is working on a switching power supply project recently. It needs TI's TMS320F28035 chip to realize the design of control circuit. In short, 28035 is used to collect the semaphore, calculate the algorithm, obtain the duty cycle, and then use the ePWM module to output PWM wave to control the on and off of the power switch, so ...

Introduction to Hexagon graphics analyzer
2 use analyzer
2.1 general
Use the analyzer after executing the application on the simulator. When the simulator executes the target application, it generates one or more data files containing analysis information. After the simulation, the profiler inputs the generated profile data file and displays the profiling information.
The analyz ...
