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...
