Hi,I developped a new version of my first card that SWD communication didn't work. So, now i manufactured a new card (check the schematic please) can you give some feedback, to know if you see a probleme with my card that can impact swd.
I'm using STM32F446.I'm generating PWM signals using TIM1 and TIM8 (on APB2, which runs at 90MHz, and 180MHz for the timers).I'm also generating PWM signals using TIM4 and TIM12 (on APB1, which runs at 45MHz, and 90MHz for the timers).I start each PW...
Chào bạn,Tôi đã thiết lập kết nối theo sơ đồ và tôi đã tải mã trong tệp đính kèm nhưng tôi không thể đọc dữ liệu từ EEPROM. Địa chỉ M24C02 của tôi được đặt thành 0xA0.Ai đó có thể giúp tôi xác định vấn đề? Cảm ơn rất nhiều.
Hi there,I have some question about the deferent about the source code and the lib.For example, I have three source code files(func1.c, func2.c, func3.c) and I compiler them to a lib file(func.lib);In my project, I just need use the function in func1...
Hello,I'm developing an application on the NUCLEO-U5A5ZJ-Q. I need some pins to stay high while the microcontroller is in Stop3 mode.The Datasheet suggests to use internal pull ups, because the GPIO peripheral is not active in Stop3 mode. For this re...
I have a board that uses the H743 and have been having major problems with the USB side of things. I've only just realised that I left VBus floating all this time, so I'm assuming that's a major cause of my issues.. The board I have is designed as a ...
Good morning to all,I’d like to ask your advice.I have to insert an external RAM for the framebuffer because the internal one is not enough for LCD that I will drive (LCD-TFT LVDS 7 inch 1024x600).Which external RAM do you recommend? Could a QuadSPI ...
Hello, I've been using the Nucleo-F446RE to program a stm32f4 series chip using the Nucleo's onboard ST-link capabiltiies. So far I have managed to get it to link and work in CubeIDE, but in CubeProgrammer it's giving me the following issue (attached...
Description of the system-memory-stored manufacturing-time-acquired constants for temperature sensor (TS_CALx) and VREFINT voltage (VREFIN_CAL) are given for certain VDDA voltage.However, what's important here is not VDDA voltrage but the VREF+ volt...
Heyho,got my custom board running, only (minor) problem until now:internal analog temperature sensor (ADC3) value seems to be off, showing something like ~60°C,while an external sensor shows about 30°C."Finger test" confirms rather the 30°C.I have th...
