Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
Hi,Can anyone direct me to an example project or code that shows how I can use an AJAX call to access information from an STM32H743 (or similar) web server?I have SSI and CGI running with LWIP but I would like to update the browser without refreshin...
Hi everybody,I'm working on a board with STM32H7. I want to understand why when I launch the debugger mode with the bootloader program. The program of the bootloader still on the memory flash of the STM32H7 after a restart (turning off the board) an...
I am testing F411RE Nucleo USART speed.Sample code is: STM32Cube_FW_F4_V1.26.0\Projects\STM32F411RE-Nucleo\Examples_LL\USART\USART_Communication_TxRx_DMAAt PC side, I am using Putty as serial receiver.So far, the highest working baud rate is slightly...
Hi,We are using STM32H747IG microcontroller in our custom board and have connected the USART1 pins PA9 & PA10 to the host processor to update the firmware using UART.The USART1 pins PB14 & PB15 are connected to the LEDs using a NPN transistor and wil...
The chip shortage has led to some complications, and I've built a batch of products using any chips I can lay my hands on. This has led to a random selection of STM32s: the F042F6P6, F042F6P7, and F070F6P6. They're mostly compatible, but my applicati...
Hi,This can be considered as a bug / something to be improved on the ROM bootloaders (at least in the L412 family):Our specific design uses TIM16_CH1 in PWM mode to control a small flyback converter. As a safety measure, we've added a pull-down to th...
Hi,I'm trying to understand the capabilities of the STM32 USB endpoints (lets say at the moment, I wan't to evaluate the USB using the STM32F429ZI Nucleo board, but my question might be portable to any STM32 with USB).1/ It's not clear to me if an en...
hi,I have 2 disks.disk is SD card with FAT. Here is all workingdisk is NVM N25Q256A. Here I have problems.For NVM memory I set sector to 4096 with page 256 bytes. This memory has erase sector 4kB. Datasheet of this memory I attached. And my problem i...
