Both the firmware available on GitHub and Android application available on google PlayStore are free to download and use. To build this you don’t need any programming or code, You just need to download the latest firmware from the below links and upload it to Pico board. Signals and waveforms are displayed on your Smartphone screen. Scoppy Project combines Raspberry Pi Pico board and your Android phone or Tablet to build a very cheap Digital Oscilloscope along with Logical analyzer. As per the Raspberry Pi Pico Pinout diagram we will connect the signal to be observed with GPIO26(pin31) and GPIO27(pin32) and visualize it in the form of waves. The board has SoC chipset, micro USB port and few component on the top and the pin names are printed on the back of the board. It has specifications listed belowįor more details about raspberry Pi Pico refer the company datasheet. It has 30 GPIO pins out of which 3 are analog pins and other pins can handle wide range of communication protocols like SPI, I2C and more.

Raspberry Pi Pico comes with a new RP2040 microcontroller chip with dual core ARM cortex M01processor with frequencies upto 133MHz.

We choose the components according to value for money. You can buy the required components from the given best buy links. The First step in our project is to know what are the components required to build the smartphone oscilloscope, So that you can check the availability and buy them online or from stores. It visualizes the wave forms on your Smartphone using an Android application called Scoppy, it shows Square wave or Sine wave and detects the signals upto 250kHz frequency for each channel. So, Lets learn how to build it ourself with Raspberry Pi Pico and some electronic components. If you need an Oscilloscope at very very cheap price than this project is like a treasure. Taking this into consideration a developer from GitHub named fhdm-dev developed a DIY digital oscilloscope whose components are 100 times cheaper than the oscilloscopes available in the market. But still hobbyists and makers cannot afford those oscilloscopes whose prices start from 400$ which is very high. Due to the latest technology inventions Analog ones are overtaken by Digital ones which are cheaper than analog ones and the visualizations are displayed accurately on LCD displays. There are two types of oscilloscopes Analog and Digital.
