Resolved! How can I use multiple USB device classes with STM32L4
Hello together,does anyone know how I can implement multiple USB device classes on a STM32?I want to use the CDC so a VCP and the DFU class so I can communicate with my chip and drive an update if needed. I am working with a STM32L452RE.It must be po...
Not able to debug code executing from QSPI memory in stm32cubeide
Hello, I wrote two separate codes for this, 1st one is bootloader and 2nd is my application code. Bootloader will jump to the application code which is placed in QSPI memory. Code is executing and running fine, But the issue is I am not able to debug...
Resolved! STM32U5xx: thank you for a really "cool" MCU
Dear STM32 team,I want to thank you, honestly, for a really great MCU chip. Well done.(just as my friendly feedback to you and company)When I say, the STM32U5xx is a really "cool" MCU - I mean two things:It is really cool, in terms of temperature:I a...
L4 CRC and U5 CRC diff
Hi, I have both stm32u5 and stm32l469. I found that there are some differences in the CRC caculation.On stm32l469:if i configure the parameter as following, function hardware_crc32_calculate_with_seed works fine, no matter the code in line 185,186,19...
DMA performance gain on SDIO
I am using STM32CUBE ide and my project has SD card access via SDIO peripheral.I am using FatFS middleware. To use FreeRTOS I enabled DMA and system works fine.After enabling the DMA I wanted to see how much read/write performance the system gained.I...
Resolved! Is STM32F103VET6 not supported to use USART1 and USB simutaneously in self-powered devices?
According to AN4879, PA9 must be used as VBUS Sensing and must not be re-used for other purposes. However, according to CubeMX, PA9 refer to USART1_TX and USART1 is the only port that supports memory reprogramming (STM32F103VET6 Datasheet Section, 2....
PLL is enabled on power on?
I'm trying to migrate my code away from Platformio, which I've previously been using, to cmake (currently using it with clion and openocd).I've got everything working but when I run my code I run in to one problem.For some reason the PLL is enabled a...
STM32F207VCT6 chip won't connect via USART to STM32CubeProgrammer
Hi. Recently I started a new personal project, where I'm trying to develop my own SMD-to-female-header PCB for the STM32F207VCT6 MCU chip. After ordering all the parts, doing some reflow soldering, checking that there are no solder bridges, and verif...
