Hi everyone,The MCU on my custom board is an STM32U585. I put RDP mode to 0.5 in order to debug the product application with CubeIDE (our custom bootloader is in secure world).RDP regression to level 0.5 works fine (non-secure memory is fully erased ...
当我通过 stm32 的 OSPI 使用 OctalRAM（IS66WVO16M8DBLL） 时，我只能读取 ID rigister 和 CFG rigister，但不能写入 CFG rigister。我希望你能给我一些技术帮助。我附上了密钥代码。PSRAM的数据表：https://www.issi.com/WW/pdf/66-67WVO16M8DALL-BLL.pdf STM32U5 系列 OctoSPI
Hi,I configured the TIM17 as "Output Compare CH1 CH1N" with "Toggle on Match mode". The CH1 signal is correct but there is no CH1N output at all. The source codes are listed below. Any comment? Thanks.The initialization call:if(HAL_TIM_OC_Start_IT(&h...
Hallo there,I use HRTIM_MASTER to retrigger HRTIM A,B;C and to trigger ADC. This works fine.Each of slave timers generate PWM signals. I works also good.As the data from ADC is ready I do recalculation of PWM duty for all 3 channels. And there is an ...
Hi, I have STM32F103 and STM32F411. I have successfully made HID mouse on STM32F103, but when I try to make the same on STM32F411, the mouse does not work: "(Code 43) A request for the USB device descriptor failed".What could be the problem?The code/...
Hi everybody.I have a sdcard code which sd buffer is placed at axi ram of mu and handle by m4 core.When m7 cpu data cache is enabled the code doesnt work on m4 core when not using debug, but it works when debugging cores.If its mpu problem it shouldn...
This forum is great, but relies on volunteers to help out. In a commercial environment were time is money, the forum is not an ideal solution in order to get fast assistance to help solve development issues.I am looking for on demand STM32 commercial...
In 50% of the PCB s where the STM32f303 (with the Y revision ) was in we were unable to code a program , as well as that problem we had some difficulties with the UART It won’t connect to the laptop, it says that the device is unrecognizable and tha...
Suggest a cam module suitable for stm32h743 Nucleo board, and I want a to monitor my motors and workspace, suggest me a suitable display. I am working on a project that pick and place objects by detecting them using computer vision. It will be helpfu...
Hello, I'm driving LED driver chip (MAX16836ASA+) with PWM output of microprocessor STM32F303CB.The issue: When turn the Power supply ON, LEDs blinked for a few moments (milliseconds).I assume that the PWM giving some output values (not zero) before ...
