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...
I am trying to turn on the LD3 LED (connected to PB3) on the NUCLEO-L031K6 board using direct register access without libraries, but it is not working. The LED does not turn on. I have configured the pin control register, enabled the GPIOB clock, and...
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...
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!
Dear fellows,I've been trying to use OCTOSPI just as serial-to-parallel I/F which is protocol-free, continously working...I'm not intending to interface with any existing serial-memory devices. That's why I noted "protocol-free".Intending just have a...
Hello, On one hand, I built an app that uses I2C, 2 UARTS, ADCs, captures PWM, provides PWM. All of them rely heavily on the use of DMAs. This app gives good results without any apparent issue. On the other hand, I built a test app on the same tar...
Hello,I'm desperate. Just want to concvert some data with the ADC3 with DMA on a H755.No chance! DMA doesn't work, and even a cyclic sample only produces the right values for the first turn. After that, only max. resolution is returned. 12 bit => 0x8...
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...
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...
