Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
I'm referring to USB hardware and PCB guidelines using STM32 MCUs (AN4879)and to USB 2.0 specification. MCU is STM32H755In case when Embedded pull-up resistor on USB_DP line, USB 2.0 OTG HS controller with embedded on-chip HS PHYs and mode = device m...
Hi, i have a question about this. Normally we use F0 series and BOOT0 pin must be connected to GND via 10K Ohm. So, BOOT0 pin were apart. But now, BOOT0 pin and SWCLK pin is same. I created a new schematic and I connected BOOT0/SWCLK to GND via 10K ...
Unfortunately I have already designed my PCB and am now hoping that I just forgot to set a jumper or whatever, but I could not find anything about it in the User Manual. Maybe someone can measure on his or her board to see whether I am mistaken.
Hello,I want to program (first time) an STM32F042K6 with STLINK-V3SET using SWD.When I try to "connect" with STM32CubeProgrammer, I get these informations : "Error : No STM32 target found!". Here is a screen :The connections are : I tried to run the ...
can you please explain me about the X2 and X3 crystal oscillators in STM32F407VGT6, LQFP100 discovery board and what about SB13,14 not fitted
I am using the RTC of the STM32F745 with 32.768kHz LSE.Principially, the RTC work correct on several PCBs.But there is one PCB where the RTC goes approx. 7 Min too slow in one hour.But if the unit is powered of and the RTC works with VBat for a while...
Posted on September 27, 2011 at 05:06Hi, Just started playing around with my STM32 discovery board, and had a problem right away. I'm using atollic trueStudio IDE and trying to load a demo project(the one in firmware package), to my microcontroller....
my question is in STM32F407VGT6 , LPQF100, resistor R26,R27, R28 is N/A and 0..what does it mean exactly i.e.,one resistor R26 N/A is connected to VDD and another resistor R27,R28 is connected to VSS(99pin)..and second question is does VSS has a supp...
