📂 Projects

Here is a list of the projects in this repository, with a brief description of each:

ADC & Signal Processing

• adc_curvefitting: A data acquisition system for temperature sensors (LM35 and thermistor) to be used for curve fitting.
• adc_potentes_test_RMS: A test project for high-speed ADC sampling and RMS calculation on an STM32F7 discovery board.
• ADC_rampa: An implementation of a ramp ADC with a 7-segment display and UART output for verification.
• adc_rms_6ksampling: A project that calculates the RMS value of three analog signals at a 6kHz sampling rate.
• ADC_SAR: An implementation of a Successive Approximation Register (SAR) ADC with a 7-segment display.
• Factor_Potencia: A power factor measurement project that samples voltage and current to calculate the power factor.
• fft_cmcis_display: A TouchGFX application that calculates and displays a Fast Fourier Transform (FFT) using the CMSIS-DSP library.
• Frecuency_mesuarments: A frequency counter that uses the input capture feature of a timer.

Communication

• ASK_frecuency_measures: A simple ASK (Amplitude-Shift Keying) transmitter that generates a 150kHz carrier and transmits data over UART.
• CAN_MCP2515: An example of how to use the MCP2515 CAN controller with an STM32F4 microcontroller.
• CAN_transiver_ejemplo: A simple CAN communication project that demonstrates how to send and receive CAN messages using the built-in CAN peripheral of an STM32F1.
• ethernet_1: A basic example of how to use the Ethernet peripheral on an STM32F7 with the LwIP stack.
• MCP2515: Another project demonstrating the use of the MCP2515 CAN controller, this time with an STM32F7.

Motor Control & Robotics

• line_follower_speedy: A line follower robot with a PID controller, an IR sensor array, and Wi-Fi communication.

GUI & Display

• Bidireccional: A TouchGFX application for the STM32F746G-Discovery board with video playback capabilities.
• TouchGFX: A folder containing TouchGFX projects.

Audio

• AUDIO_Standalone: A USB Audio Class implementation that allows you to use the STM32F746G-Discovery board as a USB speaker.

Other

• BSP: A comprehensive example that demonstrates how to use the Board Support Package (BSP) drivers for the STM32F746G-Discovery board.
• Codigos_desktop: A collection of C code examples for DSP algorithms that can be run on a desktop computer.
• Func_gen_mux: A 4-channel function generator with a multiplexer that uses PWM to generate waveforms.
• heaters: A temperature control system for a set of heaters, likely for an application like a 3D printer extruder.
• iris_plant: A machine learning application that classifies iris flowers using a model trained with Edge Impulse.
