Description DIY Mini Digital Oscilloscope Kit STC8K8A Microcontroller Electronic 1. Indicator Light: When the indicator light is illuminated, sampling is active. 2. There are three trigger modes: Automatic mode, Normal mode, and Single mode. 3. Trigger Edge: The trigger edge determines whether the trigger point is on the rising or falling edge of the signal. 4. Trigger Level: For repeated signals, the trigger level stabilizes their display. The trigger stage can capture a single signal. 5. Save Settings: When exiting the settings interface, all parameters of the settings interface and the main interface are saved in the EEPROM. Waveform Generator: PWM (PWM generator) and SIN (sine wave generator). The amplitude can be adjusted via RP1 and RP2. Supply voltage: 5 V DC (Micro-USB) Voltage range: 0–30 V (LSB must be adjusted) Level sampling: 10 kHz, 100 µs/Div Second/Div: 500 ms, 200 ms, 100 ms, 50 ms, 20 ms, 10 ms, 5 ms, 2 ms, 1 ms, 500 µs, 200 µs, 100 µs Note: Installation instructions are not included.
