I love making little machines tick—especially the smaller ones! The smaller they are, the cooler they get.
Defining a shortcut key to call the python script for Siglent screen captures has been another major flow improvement!
No longer switching USB sticks between oscilloscope and desktop! Using #SCPI commands in a python script to get screenshots from my #Siglent scope onto my desktop. What a relief! #testbench #embedded
Achieving ~5.4Mbit/s USB throughput from my #pico2 device (Full Speed) to python host on windows. Not sure if I'll be able to get more out of it with this setup... #USB #data #throughput #raspberry
While probing a GPIO pin on my oscilloscope, I noticed it toggled between 2.4V and 3.3V. Using another reference pin, toggling at exactly the same time swinged correctly between 0V and 3.3V
I think I might have damaged a pin on my #rp2350 :( #debugging #signals #embedded #pico2
Added some oscilloscope measured waveforms to my blogpost about the hc-sr04 ultrasonic distance sensor. Trigger pulse width was off from the expected width on linux. Ultrasonic pulses clearly visual as well
Expected to create a 10us pulse in python using time.sleep() on my raspberry pi:
GPIO.output(pin_trig, GPIO.HIGH)
time.sleep(10E-6)
GPIO.output(pin_trig, GPIO.LOW)
Only to see a 95.5us pulse with my #siglent scope
Looking to turn my #Pico2 in a rudimentary #oscilloscope. Have been checking the ADC's samplerate and tried measuring an ultrasonic distance sensor's echo pulse. Not quite there yet, USB throughput is still a limiting factor.
