Скачать или смотреть Tutorial CubeMX -6- Tx polling Rx interrupts STM32F4 Discovery

Using HAL API and Cube Mx code generator, only 5 lines in main.c and 2 lines in ISR are necessary for Tx and interrupts Rx for STM32f4 Discovery. The major issue is understanding the game of activating and deactivating the interrupts made by HAL instructions and macros. Here we use the blocking instructions (the Tx instruction is blocked by reception, as one may notice at the end). Anyway, we recommend the non-blocking method using the HALxxxIT instructions, as in the next video.

Unfortunatelly, the projects involving ARM microcontrollers have a rather complex structure and setup and can not be simply emailed, or downloaded. However, all the STM32F4 projects presented on this channel are fully explained in the book "ARM Microcontrollers Programming for Embedded Systems", which may be found at: https://www.smashwords.com/books/view...
Other microcontrollers projects presented on this channel are explained in the book "Esp32 Programming for the Internet of Things" found at https://leanpub.com/esp32_IoT. As the time needed for watching such videos is often too long, you may simply copy the programs from the electronic edition of the book, and paste them into your projects.
