If Alternate function IO pin is used, the later 2 should be used. This information will be processed by the HAL library at the function call. It is in the process of being refactored to support other processors, in particular the STM32 series. The concept is simple, on line 190 an init struct is defined, this struct is filled with information. You just have to choose the trigger, the function ( hardware -> memory ) and set the adresse where you want your data. I want to receive data using the HAL_UART_Receive_IT() which sets up the device to run an interrupt function when data is received. My question is can I use the HAL library with the MBED compiler? janjongboom (Jan Jongboom) March 16, 2018, 6:45pm #2 Yes, it’s included in Mbed OS 5 as well. The peripheral driver library should make it relatively easy to use. Billy, you can scroll the STM32 reference manual to see how the DMA works, there is some dedicated channels for USART and UART, it's not that hard to use. It will - of course - describe the parameters for the available functions. Sensor output is connected to PC15 and PWM to PD12. STM32 SPI HAL library [stm32] - Page 1. Lines 193 to 196 enable the clock for the. Open the folder with the library HAL_Driver, go to / src open the file stm32f1xx_hal_msp_template. Your function is a simple SPI tranfer. The HAL library contains a large number of functions that can be used to develop applications using the STM32 processors. The bootloader implementation uses the official HAL library of ST. STM32 HAL Tick Interrupt priorityPosted by m-wagner on March 30, 2016Hi @all, I've come across a problem when using STM32 HAL library in combination with FreeRTOS. It maybe easy to use with code generators like stmCube but when you try to read a code, it is impossible. Hello everyone, does anyone have an example of how to remap the USART or another peripherials pins using mbed library on the STM32? Is it possible or I have to use StdPeriph Library for this operation?. I am using STM32L053 Discovery. The USB device library is generic for all STM32 microcontrollers, only the HAL layer is adapted to each STM32 device. Hardware abstraction layer (HAL) provides us a high level, high abstraction library. Most approaches I found crawling the internet are using the LL library to achieve this and many discussions around HAL do not end in satisfaction. On the STM32 however, it really is universal. How can I reduce the size of the HAL library or otherwise make it take less of a huge percentage of my project? Try to: eliminate unused code and data ("garbage collection") using -ffunction-sections and -fdata-sections for compiler, --gc-sections for linker. There are many ways to program ADC in STM devices.
