I’m trying to read ESP ADC input voltage from TDS sensor, but it jumps randomly from 0,300V to 0,450V. The Sensor output voltage is stable (0,438V) according to my multimeter and osciloscope. I connected sensor output to one of ADC GPIOS. Should I do anything else to remove the...
有个神奇的地方,ESP的芯片有专门控制LED的外设,又因为控制LED就是控制的PWM,舵机的控制也是PWM,所以很自然的就会想到用LED的外设去控制舵机。 可以参考官方的文档 LED 控制 (LEDC) 外设主要用于控制 LED 的强度,但也可用于生成 PWM 信号以用于其他目的。它有 16 个通道,可以生成独立的波形,例如用于驱动 RGB LED...
