Hello,now I will record 32 GPIO's via DMA for the analyse. The DMA itself shall triggered with a timer.So first I have found different information to solve this. So I have tested some solution, but on the STM32F756 will it not run.My solution is: GPI...

Hello,I have buy the NUCLEO-F302R8 board with the X-NUCLEO-IHM07M1 with the motor BR2807. Now I search for the library and code generation with STM32CubeMX. It is stand on the web page that is "Workflow supporting the STM32CubeMX GUI configurator". B...

Hello,I've a project which are build with the STM32CubeIDEA Version 1.16.0. I use the tool chain 11.3.rel1. After build with optimisation -O0 the application works without problems. It is implemented with bare metal and with using of the LL version 1...

Hello,I've a project with the STM32G030F6 which the application use in 90% of time the low power sleep mode. In the reference manual page 95 is written that can debug:But in the register DBGMCU_CR dosn't exists a flag for the low power sleep mode. On...

Hello,I've a spezial question about the reading of the RTC date/time. In my project are used the STM32G030F6 with SYSCLK=64MHz and RTCCLK=32768Hz. Per reset value the BYPSHAD=0.Now I read the date/time with the follwoing consecutive two lines: const ...

Thanks all, now I found the last problem. It was the debugger. I user the winIDEA from iSystem with iC5700. And here I must configured a reset after download a new firmware. And I've forgot this. So is artifacts inside of the registers in the MCU, wh...

Thank @waclawek.jan , now I understand it.

So, I have test it. I have change DMA1 to DMA2. Now it works only for one DMA transfer. When I enable by booth timer the DMA Request update, the software crash and the debugger stop at the adress 0xbeca4cf0. The callstack give me the follwoing inform...

Thanks for our answers. I will test it today and give here a feedback.@gbmWhich first big picture did you mean?Figure 1. System architecture for STM32F75xxx and STM32F74xxx devicesHere I see that the DMA1 have connection to APB1 and DMA2 to APB2. Boo...
