Many modern microcontroller devices have more than one memory region, and you may want to locate code or data on fixed memory addresses in any of those memory regions, for various reasons. It has two LED blinking tasks running at the same time. The kernel itself consists of only three C files. The Portenta H7 is the first MCU board with a DisplayPort output over USB Type-C. For this example, we selected DMA1 Channel1, so first of all, we call DMA_DeInit(DMA1_Channel1) function, which makes sure DMA is reset to its default values. I'm happy to do that if you think that this approach is OK. in both cases you should have a bootloader to update the application. This code will generate 6 assembly lines needing 1020 bytes of code. Dual-core STM32H7 series of high-performance MCUs with Arm® Cortex®-M7 and M4 cores. For this example, I want to set up two Output Compare channels on TIM3. By using the two cores flexibly, developers can easily upgrade existing applications with more advanced and complex graphical user interfaces, taking motor control for example, by migrating old code from the single-core cortex-m4 MCU to STM32H7 cortex-m4 while running the new GUI on cortex-m7. For example on the FRDM-K64F (same device as on above TWR-K64F120M), the SWO pin is *not* routed to the debug header:. ADC in STM32 is very advanced and very complex. The embedded Flash of the STM32F7 and H7 Value Line also increases the security of the entire system. Each channel will simply generate an interrupt.
