Posted on December 13, 2017 at 17:32 In Cortex-M3, M4, etc, we can just check the DEBUGEN bit in DHCSR (the Debug Halting Control and Status Register) http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/CEGCJAHJ.htmlBut in Cortex-M...
I'm working on emulating multiple USB devices using an STM32F4xx microcontroller. My goal is to dynamically change the USB controller's address at each SOF to cover the addresses of all my devices. However, I've encountered an issue: when I read the ...
Hi,We are using STM32L452CEU6 with 48QFPN package and trying implement sleep mode 2 inside Azure rtos threadx. But the device is not entering stop mode even after calling the HAL_PWREx_EnterSTOP2Mode(). But it works fine if I call it before calling M...
I have a project which uses both OPAMPs. For both OA I use dedicated VINM pin.OPAMP1 works correctly.OPAMP2 behaves like the dedicated pin (M2 ball) is not connected to the input multiplexer.I 've tried - mode FOLLOWER: OK - mode STANDALONE, reconnec...
In STM32H503 USB device mode, I found that SOF interrupts are periodically lost, SOF interrupts trigger normally in about 300ms,then SOF interrupts does not trigger in the next 300ms,and so on, if ESOF interrupt are enabled, ESOF interrupt will trigg...
I am trying to design my own microcontroller and I am following this video here the guy is using the ams1117 as his linear regulator which has a current output of 1 A, wouldn't this fry the MCU? I read the datasheet for the stm32f405 and in the min/...
Hello,I am designing some hardware with the STM32H523.I have a rechargeable ML-Lithium Coin battery directly connected to the VBAT pin of the controller. The battery is supposed to power the RTC when there is no VDD. I would like to use the internal ...
Please go and visit our wiki pages Basics of power supply design for MCU. This article covers general aspects about designing power supplies for STM32 based applications. It provides general guidelines on important characteristics, how to choose comp...
Hello everyone,I have a stm32h573. I want to get 24 bit resolution. There were those who said I could do it in dual mode. Can I get 24 bit adc resolution using dual mode? There is a 36 bit CDR register. But I really want to know if it will give 24 bi...
I'm trying to build a server using STM32F207 processor and LAN8742A I have used CubeIDE to generate the configuration code and modified as follows: 1) ETH -> Auto negotiation Enabled -> PHY Address = 0 -> PHY SR Offset = 1F ...
