Hello, I have designed my PCB with stm32f427VIT6 and a 24Mhz crystal oscillator. I was trying to upload and test the normal blink code and it's not working. If I disable the external clock, the LED works and does not work with an external clock. I am...
Hello, I am looking for a solution to my problem.I am using an STM32C031 to light LEDs using SPI signals.I am using a connector to connect the STM32 mounting board to the LED mounting board. The connector connects the DC power supply and the SPI sign...
Hello,I am trying to find available solutions for below requirement.I am using STM32H743 MCU in a design and I want to add external SRAM of 128Mbytes to the design.I understand can do this with FMC, but the problem is available pins for the FMC are c...
Hello,I am trying to use the SLEEP and STANDBY modes with the RTC. I want the device to go to sleep/standby mode for 10 seconds and wake up after the 10 seconds are done. I have tried it with an interrupt using UART and Button and both the modes are ...
Hi,I have two custom boards using the same OCTOSPI HyperFlash and for some reason the memory fails to run at higher speeds with U5-board.Board 1-H7 MCU at 550 MHz-OCTOSPI at 160 MHz works fine! (max clk is 166 MHz)Board 2-H5 MCU at 160 MHz-OCTOSPI at...
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...
