Here is something pretty handy some times: https://x-io.co.uk/serial-oscilloscope/ (11-3-2021) You can use it with this module in B4R: https://www.b4x.com/android/forum/threads/module-serial-oscilloscope.128394/...

Here is a module that communicates with the serial oscilloscope as seen in this thread: https://www.b4x.com/android/forum/threads/serial-oscilloscope.128346/ As far as my knowledge goes it is not... that I have). In order to face this and since it is a nine channels only oscilloscope I created it as a module...: SerialOscilloscope.Initialize(6) 'Change the number to the channels you will need AddLooper("osc") And of course also this sub in Main module: Sub osc SerialOscilloscope...

TFT low frequency oscilloscope, bandwidth is DC to 2000Hz. Max sampling rate is 40000 samples per second. An oscilloscope with these specifications has limited use, but it is a good exercise in using LCD TFT. Arduino can be Uno or Nano. The screen is constructed from 32 lines. The ADC reads the input at resolution of 10 bits, the MSB 8 bits are stored in the RAM and then transmitted to the LCD RAM by 4 wires SPI. C code is for the SPI and setting the ADC to max speed. The Sweep time...
