Product introduction:

This is a simple oscilloscope made with an STC8A8K microcontroller. It only requires a small amount of components and is easy to assemble. The function can cover simple measurements. This kit aims to build a basic oscilloscope model with the simplest possible principles and as little hardware as possible. The source code is easy to understand, and it is also very suitable for interested electronic enthusiasts to learn and research while using the product.

Feature:

Product name: MiNi-DSO microcontroller oscilloscope kit Product model: TJ-56-646 PCB size: 57 * 34mm Working voltage: 4-5V Single chip: STC8A8K64S4A12 Display: 0.96 inch OLED display screen -7P, 128 * 64 resolution Number of channels: single channel Sec/div: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us (100us only available in automatic trigger mode) Voltage range: 0-30V Sampling level: 10kHz@100us /Div Trigger level: Trigger voltage level Trigger slope: ↑ - rising edge, ↓ - falling edge trigger Trigger mode: A-automatic mode, N-normal mode, S-single mode.

Description:

Trigger level: For repetitive signals, the trigger level stabilises the display. For single-shot signals, the trigger level captures it. Trigger Slope: The trigger slope determines whether the trigger point is on the rising or falling edge of the signal. Trigger Mode: Auto Mode: continuous scanning. Click the encoder to stop or run sampling. If triggered, the waveform will be shown on the display and the trigger position will be placed in the centre of the graph. Otherwise, the waveform will scroll irregularly and display "Fail". Common Mode: After the pre-sampling is completed, you can input the signal. If triggered, the waveform will be shown on the display, waiting for a new trigger. If there is no new trigger, the waveform will be kept. Single Mode: After the pre-sampling is completed, the signal can be input. If triggered, the waveform is displayed and the sampling is stopped. User needs single point encoder to start the next sampling. When in common mode and single mode, make sure the trigger level has been adjusted correctly, otherwise the waveform will not be shown on the display. Indicator light: Normally the indicator light is on to indicate that sampling is running. *Save Setup: When exiting the setup interface, all parameters of the setup interface and main interface will be saved in EEPROM.
