Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello,I work in a company that uses stm32F031C4T6 and we manufacture 40,000 cards a year with this reference. I was wondering if it would be possible to ask the manufacturer to program the microcontrollers directly in their factories, because for our...
Hi All,I am working at project with STM32H7 and NetX Duo. At current version of Ethernet driver from ST (X-CUBE-AZRTOS-H7 v3.0.0) is not handled by any way state when link is disconnected. Link status variable nx_interface_link_up is set at "Enable L...
I'm trying to set up a DMA transfer from UART1 periheral to memory. Using LL drivers. Using STM32Cube for "convenient" setup. It puts the all the USART peripheral init in usart.c. Where for GPDMA it does something like: /* GPDMA1_REQUEST_USART1_R...
We are using STM32H723ZG on custom board. Sometimes, we want to jump to System Bootloader (address 0x1FF09800) from our application. Then we connect to device via USB DFU. I thought that it works reliably, however we discovered that sometimes, there ...
Hi,I want to make PWM stream with various duty, so I'm testing PWM with DMA using NUCLEO-G0B1RE and HAL library.The first image shows weird pulse train. I set DMA buffer with [duty 1] * 8 + [duty 17] * 8 + [duty 5] * 8, but oscilloscope captures eigh...
Hello,I am trying to do an OTA upgrade on my STM32H750. I am using QSPI flash in dual mode as the IC does not have so much internal flash for my application. My application is running FreeRTOS and does have a LCD screen. So I build a bootloader to co...
Hi everyone. I'm using stm32f767zi board with lwip stack and I need to transmit at different rate through Ethernet: 50mbit/s, 80mbit/s and 100mbit/s. When I tried to send a buffer of 6554 byte every 1ms (in order to send 6553600 byte aka 50mbit every...
I am working on EEPROM Emulation in STM32L432 using its internal flash memory so is there any specific address for making EEPROM emulation in stm32l432kc or can we take any random address of flash memory? give the solution.
Hello,I'm working with the stm32f439ZG and I have one question regarding the CAN bootloader.I'm trying to update one node via CAN interface. I have one network with 3 nodes (the node 1 is responsible for send the new firmware, the node 2 will receive...
When the HAL_ETH_Transmit is called by the driver it seems the code below (part of HAL_ETH_Transmit ) times out as the DMA TX complete callback are not called. I've followed the STM32H743 example but I guess STM32H742 memory map is a bit different th...
