HAL Library 27- Identification for STM32Fxxx 1

HAL Library 27- Identification for STM32Fxxx

If you wanna take a control on your software (secure your software by selecting package you want, device you want and others) you can identify STM32Fxxx device. This library allows you to read several things from device, like unique ID, flash size, package type, device type and maybe more. I’ve ported my old library to HAL based drivers, which now supports STM32F0xx, STM32F4xx and STM32F7xx series.

HAL Library 26- Power Voltage Detector (PVD) for STM32Fxxx 1

HAL Library 26- Power Voltage Detector (PVD) for STM32Fxxx

Power Voltage Detector (PVD) can be used to detect if power voltage is below or above selected voltage. It can be used for closing file using FATFS when detected voltage below treshold so you don’t break data on card or similar thing, sky is the limit here. PVD allows you to select 8 voltages between 2 and 3 volts. For detailed voltages, check reference manual.

NRF24L01+ 2.4GHz RF Module 1

HAL Library 25- NRF24L01+ for STM32Fxxx

I spent some time again porting libraries from STD drivers for F4 series to HAL drivers for STM32 series. This library is going to be about NRF24L01+ transceiver module, allowing you to send and receive data between 2 NRF24L01+ modules connected to STM32Fxxx device. Library Read more about new HAL libraries Features Send and receive data using NRF24L01+ Allows to use IRQ pin on NRF24L01+ Functions to read and clear interrupts are in API

HAL Library 24- RTC for STM32Fxxx 22

HAL Library 24- RTC for STM32Fxxx

RTC library was ported to HAL drivers for STM32Fxxx line from my previously library RTC for STM32F4xx. If features similar things as before except some functions were changed, which are already described in HAL API. Library Read more about new HAL libraries Features Support Internal or external clock source PC14 and PC15 pins are used for external crystal oscillator STM32F4/429 Discovery does not have RTC crystal onboard. Check board’s manual on how to set it up Support wakeup interrupt Support...

HAL Library 23- TOUCH for STM32Fxxx 6

HAL Library 23- TOUCH for STM32Fxxx

The TOUCH library is a “high” level library for touch operations. It requires low-level drivers for communication with your sensor/device, but for high level for user, always the same functions are used. This allows you flexibility between multiple low-level device drivers to be used with in your project if needed and also allows single lib to have the same features for all projects. Library Read more about new HAL libraries Features Custom selectable driver Built-in drivers for STM32F429-EVAL and STM32F7-Discovery...

HAL Library 22- BOR for STM32Fxxx 1

HAL Library 22- BOR for STM32Fxxx

BOR (Brown Out Reset) is a way to reset microcontroller if target voltage is below voltage we set. When this happens, MCU is in reset state until voltage comes above selected voltage. STM32F4/7xx devices have 4 possible BOR values, which are described later or in API documentation.
