STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Hi,I am stuck on this issue on the STM32U5A9J-DK. I have ported the USB part from a H725 i have running. Where i have copied the init code from generated code.In USB_CoreReset() the USB_OTG_GESTCTL_CSRST bit is never reset and hence a timeout occurs....
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...
