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...
Dear all,I have Stm32f7508-Dk ,I am trying to execute the BSP examples one by one Everything is ok but got stuck in Audio loopback As per instruction (Read Me file) we have to give input to Microphones U20 , U21 and we got the output in CN10 But i ca...
Hi, I am unable to get DHCP working. I am using the DP83848 board with an STM32F4 Discovery board. I am using the STM32CubeIDE and so had the code generated, the DP83848 is working on RMII mode.When I enable or disable DHCP and connect it to my PC/la...
The short version is I'm trying to get a very basic setup working;STM32L152 using Cube IDE, I want to sample ALL 22 ADC channels continuously into an array using DMA.I've copied and pasted the 'ADC_MultiChannelSingleConversion' case into my pretty ba...
I am trying to write in the SD card in polling mode and it works successfully first two time and when i try to open the same file and write to it is fails and stuck at function " HAL_SD_ReadBlocks " at file stm32h7xx_hal_sd.c at the following conditi...
