I'm working on a solution using STM32H753 MCU. HRTIM1 TIMA needs to generate short periodic 100 ns pulses periodically and drive MDMA channels. This already works fine.In addition to above, I need to drive GPIO F8 low for a short 500 ns time window t...
I'm trying to do something that seems simple if you go a search. I want the module to sleep. Then I will wake it with voltage on pin B6. I don't want an interrupt. Just an event. People mix event and interrupt so much and all the examples I see are b...
Is it possible to change the FLASH write protection at run time without reprogramming the option bytes?The write protection registers are writeable after unlocking, but it appears as if changing the value has no effect on the actual write protection;...
I am using stm32f103c8t6 with uart cable to connect it with stm32 cube programmer but come up the statement above. Any suggestion to fix this problem?14:12:16 : Serial Port COM3 is successfully opened. 14:12:16 : Port configuration: parity = even, ba...
Hello everyone,I'm current creating my first STM32 design using STM32F411 and have a need for the USB function on the MCU. The datasheet states that it requires a 48 MHz clock generated by a PLL connected to the HSE oscillator.And I've currently chos...
Dear,Recently, when working with STM32U575 and using WWDG, I've encountered an unclear behavior when I set the controller to STOP mode by using HSE or HSI clock source.By using HSI and LSE clock source (See below code), when enter STOP mode, WWDG is ...
Hi there I'm working on a project where I need to create 4 different pulse trains on 4 different GPIO pinsI've created and formatted a uint32_t array to be able to directly write to the GPIO BSRR registerI want to use DMA memory to peripheral in circ...
Hi everyone,I'm working with an STWINBX1 board and using ST-LINK V3MINI for debugging and serial communication. However, I can't see any output on PuTTY (COM3 @ 115200 baud), even though everything seems correctly configured.Setup Details:Board: STWI...
Hi all,I'm designing a product that will have a USB boot-loader.I would like to choose a micro-controller that supports secure-boot as well as an ability to completely lock down the micro-controller such that no flash can be read from it. I understan...
Hi am relatively new to stm32 development.I would like to understand the difference between HAL_GPIO_EXTI_CLEAR_IT and HAL_GPIO_EXTI_CLEAR_FLAG Thank you!
