Libraries and tutorials for STM32F4 series MCUs by Tilen Majerle
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
In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like!

If you modify source code, it has to stay under GNU GPL v3 license too. I...
For FFT project purpose, I needed simple, really simple signal generator. I don’t have separate device at home, so I made one with STM32F4. DAC Signal library uses timer for output generation and DMA for transferring data from memory to DAC peripheral. So this library does not use processor for controlling. Everything is behind the scenes. You can use 4 different signal waves: Square Sawtooth Triangle Sinus They are simple, predefined signals. You can adjust signal frequency for specific wave. I...
Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
Digital to Analog Converter has inverse function as ADC. It converts digital value in microcontroller to analog value. Library Features Output analog value from STM32F4x Dependencies CMSIS STM32F4xx STM32F4xx GPIO STM32F4xx DAC TM TM GPIO defines.h STM32F4 has 1 DAC with 2 channels output. Table below shows pins for DAC. DAC pins DAC Channel ALIAS Pin APB DAC_Channel_0 TM_DAC1 PA4 1 DAC_Channel_1 TM_DAC2 PA5 1
