Re: mcpwm_set_frequency() equivalent for esp-idf v5.0 PostbyChrisP_SD»Tue Sep 26, 2023 3:51 am Yes, thanks for the suggestion. I did look through all of those and ran the mcpwm_servo_control on my ESP32-S3 to generate a PWM signal. The mcpwm_bldc_speed_control is almost what...
MCPWM 单元的更详细框图如上所示。每个 A/B 对可由三个定时器定时器 0、1 和 2 中的任何一个提供时钟。同一个定时器可用于为一对以上的 PWM 输出提供时钟。每个单元还能够收集输入,例如检测电机过流或过压,以及获得反馈,例如转子位置。SYNCSIGNALSFAULTSIGNALSCAPTURESIGNALS ...
