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...
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...
Hello,I'm have a Nucleo board with a STM32F334R8T6I configured a timer with 10kHz and I'm using the HAL_TIM_PeriodElapsedCallback to call a funtion that will control my motor and read some data with the ADC. I want to check the frequency that the con...
Hi,Recently I had to replace the MCU in a device and I tried to upload the code using USB Bootloader, as it is available and requires very little stuff when you're on site.So, the MCU has been detected in the system (see PIC1.png), but the CubeProgra...
How to write code for TCP client on the STM32F767ZI based NUCLEO board without using any RTOS on STM32Cube IDE? Do you have any example code? Also looking for TCP server code that is working... Please respond with details and the sample program if yo...
Hello,I have a digital buck converter with hrtim. I followed examples Buck_VoltageMode_HW etc. So far so good, output is stable, well regulated to fixed value.But what if want adjustable output by the user? What is the strategy to do that? I can do a...
