Hello,I am learning bare metal programming for STM32F446RE and am trying to write a simple transmit driver for USART2. I managed to do it but my only problem is when I use HSI 16Mhz clock speed (or anything lower) I get a weird first character. When ...
I'm using a B-U585I-IOT02A board and the IOT_HTTP_WebServer example code. My read is the PSRAM is 8M on that board, but I can only access 16K (to 0x2803ffff) and then ???? is not IDE memory display or a trap in the code. Is this a CPU configuration ...
I'm trying unsuccessfully to erase a 4K sector at 0x73ff0000 using STM32CubeIDE code, but the STM32CubeProgrammer works fine. I've tried using BSP_OSPI_NOR_Erase_Block() and MX25LM51245G_BlockErase() with no luck. My code base is the HTTP_IOT_WebSer...
I'm designing a custom PCB using an STM32F103 microcontroller to control a triac-based light dimmer. The firing angle for the triac is determined by reading the voltage from the potentiometer.The potentiometer output is routed through a header and th...
I wanted to do a full chip erase using STM32Programmer (I am trying to debug a custom bootloader) but kept getting the error "Mass erase operation failed. Please verify flash protection".I sent the following option byte screenshot to ChatGPT....Chat...
Hello,I have a STM32G0B1KBU3N MCU for my USB-C PD board. I am a new with this so learning. I am currently finished assemble my own PCB and have some issue with programming the controller. I can program controller with ST link V3-minie but have Zero l...
Reading STM32U5A5 Rev. ID returns 0x3003 using STM32Cube HAL API that is not listed in Reference Manual (RM0456). What is the revision of this product? The Reference manual lists only 0x3001 as revision X and 0x3002 as revision W.Thanks.
Hi, we are developing a device which outputs display port over type-c and needs to sink power. Similar to Laptops when connected to hubs. The required power is less than 60W. Im looking a for a suitable USB-PD implementation for this purpose. Can thi...
Hii Everyone, I am trying to debug with SWO and SWV in STM32CubeIDE with NUCLEO-H753ZI. But, I am not getting any prints on SWV ITM Data console. As you can see all settings in the below attachments. My CPU system clock is running at 400Mhz. Anyone s...
Hi all,After reading through both the HAL, low-layer and USB Device library code flow several times I am still confused about a peculiar point.When I ask STM32CubeIDE to generate a Custom HID base implementation, I get a "usbd_conf.c" file that has a...
