Hello, I’m working with an STM32F446 and have configured GPIOB pin 12 as an EXTI input. After initialization and before entering the main while loop, I call a function that blocks program execution(what I mean by blocking : I have a test that stands ...
Hello there, I'm playing with the NUCLEO-H743ZI2 board and having difficultis with PTP. When TSIE (MACIER is set the interrupt is getting retriggered endlessly. I've tried to clear TSIS by reading both MACISR as well as MACTSSR (TXTSSIS bit set). The...
Dear ST Team,我用usb转ttl单独对4g模块发at，回复消息是正常的，单独模拟给单片机发数据，回应的数据也没有丢字符，就是4g模块跟单片机之间通信的时候存在问题When I use a USB-to-TTL adapter to send AT commands to the 4G module alone, the responses are normal. When I simulate sending data to the microcontroller alone, th...
In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...
Hello,For the last couple of days I have tried to create a bit stream with DMA using a timer but have not yet succeeded. The problem seems to be loading the data from an array into the timer register. I have tried this exact same code on an STM32L072...
Hi We are using an STM32U073CCT6 on a battery-powered board. We need to put the processor in low-power mode to increase battery life. The current in STOP MODE 2 is about 20uA. To address some issue related to the power supply and our hardware, we put...
This previous thread refershttps://community.st.com/t5/stm32-mcus-products/stm32f4xx-does-going-up-a-package-pin-count-impact-pin-af/td-p/862282The 437 is curiously a very close superset of the 417. Apart from the extra 64k RAM, the only difference i...
Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
