STM32_Drivers

Here are the FPU, UART, Timebase, GPIO, ADC and Circular drivers for the NUCLEO-F446RE board.

This repository is part of a bigger project where an SMT32 NUCLEO board is connected to a ESP32 WROOM32 so it can later reach an AWS Lambda function to store, read and delete readings. https://github.com/ewardq/STM32_with_ESP32_and_AWS_Lambda

How to use this project

This project is meant to be used with the STM32F4xx series of microcontrollers. Clone the repository and use the specific-library files at your will on your STM32 project or directly copy the code in the .c and .h files.

The libraries are incremental; the GPIO #3 library also includes the #1 FPU and #2 UART libraries. The libraries in this proyect and their purpose are as follows:

1. Float Point Unit enable library to be able to use float data type. [ fpu.c | fpu.h ]
2. Universal Asynchronous Receiver-Transmitter library to be able to use the UART1 port to communicate with another microcontroller and the UART2 port as a debugging tool (Serial Console needed to visualize debugging messages from the STM32). [ uart.c | uart.h ]
3. Timebase library so you may use timers, delays and counters. [ timebase.c | timebase.h ]
4. General Purpose Input Output library as an example of how you can use the GPIO ports as digital input/output. [ bsp.c | bsp.h ]
5. Analog to Digital Converter library so you may use analog inputs and processes them later as you need. [ adc.c | adc.h ]
6. UART Communication Buffer library to better process characters comming from another microcontroller and later be able to send characters without risking overflow. [ circular_buffer.c | circular_buffer.h ]
7. ESP32 library to setup the ESP32 microcontroller in modem mode. [ esp32_lib.c | esp32_lib.h ]
8. ESP32 client library to interface with the ESP32 WROOM microcontroller in Modem mode. [ esp32_client.c | esp32_client.h ]
