Large G-Code File in PLC Program for laser CNC machine
HC-SR04 Distance Sensor for Raspberry Pi
I added library and xml file and I get 58 errors and placeholder not resolved
I am trying to get a PWM circuit to work, I only need one channel for lase control and Raspberry Pi has it, GPIO 12 or 13, how do I enable and control it? I do see a function GPIO that has PWMFrequency and duty cycle
I am trying to use the PCA9685 board with PWM output. I can only seem to change the voltage never full range of 0V for no PWM, and 5V for full PWM. I can only change Frequency [Hz] the higher the frequency the higher the voltage range, also other parameters do not effect it like _alrMin, _alrMax, _freq, _rPeriod 100hz Frequency = Adafruit_PWM.alrPWM[0] :=0 is 0.468V and 1 is 0.972 output does not appear to actually PWM, higher frequency 400hz Frequency = Adafruit_PWM.alrPWM[0] :=0 is 1.949V and 1...
Here is 400Hz PWM
Here is 100hz PWM signal
