Sipeed Series

In this experiment, an LCD based on the Hitachi HD44780 controller was used. In this type of screen, there are liquid crystals inside that when they are passed through by a current, the crystal becomes opaque, blocking the light (backlight) that tries to pass. Therefore, the various combinations of specific crystals on and off  make it […]

The I2C protocol describes the operation of a serial communication bus that uses just two wires. Invented by Philips in the early 90’s, this protocol is widely used to connect low-speed peripherals to motherboards, microcontrollers, and related devices. In this tutorial, I am going to establish the I2C communication between the Maixduino and the 0.95inch

Face detection can be regarded as a specific case of object-class detection. In object-class detection, the task is to find the locations and sizes of all objects in an image that belong to a given class. Face detection answers two questions: Are there any human faces in the collected images or video? Where are the

A Solar tracker is a system that positions an object at an angle relative to the Sun. The most common application for solar trackers is the positioning of photovoltaic (PV) panels (solar panels), and it is important that they remain perpendicular to the Sun’s rays . PV solar trackers adjust the direction that a solar panel

Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up and down in a vertical plane. Tilting the camera results in a motion similar to that of someone raising or lowering their head to look up or down. [1] In cinematography and photography, Panning means swivelling a still or video camera horizontally from a fixed position. This motion

An ADC converts a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal. The conversion involves quantization of the input, so it necessarily introduces a small amount of error or noise. Furthermore, instead of continuously performing the conversion, an ADC does the conversion periodically, sampling the input, limiting the allowable bandwidth of the input signal. [1] In this tutorial, I am

Servo control is a method of controlling servos by sending to the servo a PWM (pulse-width modulation). The parameters for the pulses are the minimal pulse width, the maximal pulse width, and the repetition rate. Given the rotation constraints of the servo, neutral is defined to be the center of rotation. Different servos will have

MicroPython is a lean and efficient implementation of the Python 3 programming language. It includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. Micropython makes programming on K210 hardware easier. The code is open source and can be found on GitHub. After frustrating attempts

In this tutorial we are going to explore the APU (Audio Accelerator) of the Maixduino. The Sipeed M1 chip comes with a high-performance microphone array processor that can achieve the following capabilities: Sound Source orientation Sound field imaging Beamforming Voice wake up Speech Recognition The Maixduino has an onboard MEMS microphone. In simple terms, the

In this second tutorial, we are going to explore the display and camera of the Maixduino. The documentation is scarce and the examples even worse, but we are going to make it or break it. Tutorial #1: Getting Started With The Maixduino What Will We Need The Maixduino Board (Affiliate) – Buy on AliExpress The
