Hello,on the STM32H7S78-DK board only USB2 (=USB-FS) can be used to connect the board to a PC and flash the firmware via USB-DFU because only PM11 and PM12 are supported by the internal USB-DFU bootloader. Is there a way to modify the board or to cre...
Hi, Refer to NUCLEO-H753ZI's schematics - mb1364-h753zi-c01_schematic.pdf 1. About 8 ADC channels go to CN11 and CN12 on this schematics without the pin numbers denoted.. Do all pins on the connectors CN11 and CN12 accessible since there are ...
Greetings, we are using a STM32F469i-DISCO development board for one of our projects. We are unable to establish Host USB OTG FS communication. The USB shows that it is idle state so we are not able to transmit or receive any communication. We want t...
Hi everyone,I want to use my evaluation board's RTC Backup Registers to store some info when not powered. In order to do that i want to connect an CR2032 battery to the Vbat pin of the controller. Below is the part of the schematics of the board show...
Hello, Please help me.I'm a beginner to designing stm32 hardware designs. I need to program my STM32F413VGT3 microcontroller using SWD(Serial wire debugger). Also I need to use SWO option. I designed a circuit for this.1. I want to know about can I u...
I have been trying to get a PWM output from PE9 by following some example online. However no PWM output at PE9 pin. The desires PWM frequency is 20kHz and duty cycle is 50%. Any suggestion what is the problem ?. Thanks.
I wrote a code for stm32h745, masking the M4 core, and debugged it for two weeks without any problems per se, but yesterday, I realized that I could download the code, but in debug, I noticed that the data in RAM changes, and I didn't make any change...
Hi, I was looking at the GPIO on the STLink3 PWR and trying to find some logic analyzer but i dont find any. Someone know if that gpio are able to do logic analyzer and if yes, a software to do that ? Thanks in advance,
Hello ST Community. I have a STM32H755ZI-Q Nucleo board that I seemed to have blown up the STM32 part. I suspect this because the board is getting an overcurrent condition. But have some questions so I can better understand what may have caused this....
Hi, I was wondering if there is a reference design available for STM32WB55 based product. I am designing a system based on this MCU using the datasheet and application notes such as AN5165, but it always helps to see implementation of existing produc...
