HAL Library 07- USART for STM32Fxxx 54

HAL Library 07- USART for STM32Fxxx

Here it is. UART library for HAL based libraries. If you don’t know, how UART work on STM32Fxxx devices, then you might take a look at my first library, where I also explained how to used it. This library works successfully on F4 and F7 based devices for now. I will add support for F0 too as soon as possible. Library Read more about new HAL libraries Features Supports up to 8 UART peripherals at a time Interrupt driven RX...

HAL library 06- DS18B20 for STM32Fxxx 18

HAL library 06- DS18B20 for STM32Fxxx

When you have onewire library done, it’s easy to make interface for DS18B20 sensors. Library Read more about new HAL libraries Features Search sensors Read temperature Set resolution for each device from 9 to 12 bits Start temperature conversion on all devices simultaneously Set alarm low and high temperatures Disable alarm temperatures Search devices with alarm flag set

HAL library 05- OneWire for STM32Fxxx 12

HAL library 05- OneWire for STM32Fxxx

Next port from STM32F4xx STD drivers to STM32Fxxx HAL drivers was done for OneWire library. This library is protocol based only. It features basic functions for read/write byte, reset port and search devices on OneWire port. 1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. It’s used in some temperature sensors, like DS18B20 temp sensor and many others products from Dallas. Library Read more about new HAL libraries Features...
