stm32g474ve , dma can be triggered using external interrupts, but dma cannot be triggered using software. In theory, both external interrupts and software interrupts should trigger events. At the same time, I have verified that stm32h750 is OK. So ...

Hello everyone, I am trying to generate sine wave using DAC and interrupts in my STM32F446 board. I want to do it without using array model. I am getting b infinite_loop when the program is run in debug mode. I have initialised "use float with print...
I'm planning to drop in an STM32L083RC into a design made for STM32L071/073/083RZ (LQFP64) and was confident after reading AN6091 that apart from USBVDD it would be pincompatible.It appears I cheered too soon, after I dived into the U083 datasheet an...
Hello, good afternoon.I'm using a stm32103c8, and I'm having a serious error when writing to the flash. I'm working on a project where I use timer4 and I'm doing a multiplexing between 8 pins where I control the LED and button, but when I write the L...
