Description
Details
DSO138 was designed as a 'training' oscilloscope kit. Simplicity in structure and ease of assembly/operation were the main design goals. To meet this goal, DSO138 uses mostly through-hole parts.
This oscilloscope is partially open-sourced, which means source code is available to allow user to add their own features. At the heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. Of course, the MCU has been pre-programmed, so no re-programming is required. It uses 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element to ensure clear waveforms.
Detailed assembly instructions, troubleshooting guide and schematic are provided.
