STM32F401 (Blackpill) – 2.4s Drift in 30 Minutes Between Two Identical Boards Using TIM2 (HSI Clock)I am working on time synchronization between two identical Blackpill STM32F401CCU6 boards.Both boards:Use internal HSI oscillatorSame firmwareSame clo...
HiI am drawing a PCBA with STM32H7R3V8H6 but for the USB HS interface PHY its not clear which pins are USB differential D+ and D- data pins?krØystein
HiDo QUAD SPI require power on the VDDXSPI power pins?ADCs, what is the voltage reference buffer, VREF+ and VREF- , voltages? Can the internal reference buffer be used if VDDA is 3.3V and I want full scale 0-3.3V ADC conversion range?krØystein
The Reference Manual (RM0454) of the STM32G0B0 points to an old 2020 revision while on the website it shows 2025.I believe this is a mistake since there should be a newer revision of this RM with the fixed Flash section (STM32G0B0CE) unless ST only f...
Here comes another query about the status of a HUB device for the USB Host library. I have been working with the driver from herehttps://github.com/moribr/STM32F4HUB/blob/master/Project/Middlewares/ST/STM32_USB_Host_Library/Class/HUB/usbh_hub.cand ha...
Hello. I have a custom board with original f103c8t6 (sampled from eStore). PWM for pin PB4 is not functional, but bit banging with gpio write works. If tim3 respective channel is configured as pwm output, the output is stuck at VCC. I configured the...
Hello everyone, I am quite new to this and I am using the STM32G474RET6 with BOR level 4. I changed the BOR level to level 0 and the board did not work properly. After changing it back to level 4, everything worked fine again. Is there any relationsh...
Our product is battery powered and uses an STM32L072CZT6.I did not write any of the power management code and I am not sure exactly what modes are used.When cold started and left to go into power saving mode, the current drawn by the entire product a...
Hello everyone! In our system we have a set of subsystem that uses F4/F7 MCUs and one - with STM32H743 MCU. We want to use system CAN bootloader for all of them. Everything seems ok, except STM32H743 device. From AN2606 we know that it starts in boot...
I followed the steps in this demo workshop to upload a simple program to toggle LEDs to the Nucleo-N657X0 board. The project is in FSBL. I can run the code in debug mode and upload the signed program to the external flash on the Nucleo-N657X0 board w...
