HAL Library 28- Digital to Analog converter for STM32Fxxx 1

HAL Library 28- Digital to Analog converter for STM32Fxxx

Here it is. After many email about this library, I’ve finally made it. This library works on STM32F0xx, STM32F4xx and STM32F7xx based devices, where DAC is supported. For example, STM32F401 and STM32F411 does not support DAC. Library Read more about new HAL libraries Features It does not use built-in HAL support for generating signals Output is based on user value Independent 2 DAC channel outputs with 12-bit resolution

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. Library Read more about new HAL libraries Features Read device type with software, Read...

HAL Library 24- RTC for STM32Fxxx 23

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 8

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. Library Read more about new HAL libraries Features Set Brown-Out detection value Get Brown-Out detection value

HAL Library 18- RNG for STM32Fxxx 1

HAL Library 18- RNG for STM32Fxxx

STM32Fxxx devices (in most cases) have True Random Number Generator (or RNG). This peripheral can provide 32-bits random number. I made a small library, that you can enable and use it very quickly which is compatible with HAL based drivers. RNG on STM32Fxxx is based on analog circuitry. It makes analog noise and that noise is connected to linear shift register. Analog circuitry is designed from ring oscillators whose outputs are XORed. For RNG circuitry is also separate LFSR clock...
