Re: I CANT RECEİVE ANY MESSAGE FROM A CAN BUS ANALYZER WİTH STM32 BOARD
You don't initialize sFilterConfig to zero, so sFilterConfig.FilterMaskIdLow could be a random number upon POR.

Resolved! LWIP with Ethernet Cable Disconnected
I am using a Nucleo-F429ZI with FreeRtos and LWIP. I am having an issue with LWIP when I start with a disconnected Ethernet Cable and then when I connect it back when the firmware is running.I have a thread with the following code. 1 - The gnetif str...
Resolved! STM32F030F4 with 32K of flash?
Hello! I am experimenting with a STM32F030F4P6. When I connect it to STM32CubeProgrammer via bootoader (UART), there is an info saying the micro has 32Kb of flash, instead of the expected 16Kb for this part.Is it possible that this microcontroller re...
Resolved! UART Rx Buffer
Hi Comunity, I am very new to STM and got some problems on serial UART. I can get data from my serial, but my problem is if the data received is less than the length of the array, the next data received doesn't overwrite the first data. How do I fix ...
STM32G030 USART and HAL_Delay strange behavior
Hello all, I've recently received a dev board for STM32G030F6 microcontroller and I wanted to make a simple USART test before continuing. I've started the project using STM32 CUBE MX initializing serial port and clock, also, I've retargeted printf as...
Resolved! Cortex M33 fault handlers not being executed
Fault handlers that work on M4 and M7's aren't being executed on an M33. The Usage Fault I'm creating (via an undefined instruction) appears to be escalated to a Hard Fault. The Core stops executing instructions before ever reaching a handler. Is ...
SRM32G030C6T6 : Delay in ADC conversion (Scan mode with DMA)
Folks,I have setup the ADC to operate in scan mode, there are two analog channels to be converted. The CPU is running at 64 MHz and the ADC is running at 32 MHz. I am using the void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) to start processin...
Resolved! Problem of porting LwIP to STM32H573I-DK
Hi Everyone,I'm trying to port LwIP to STM32H573I-DK and has referenced to:1. GitHub - STMicroelectronics/stm32h5-classic-coremw-apps at v1.0.0 2. GitHub - stm32-hotspot/STM32H7-LwIP-Examples: Ethernet examples using LwIP + FreeRTOS for STM32H7 Disco...
Resolved! STM32U5xx: QSPI as regular SPI - not possible! - needs external tricks
Dear STM32 team,I am a bit confused about the OCTALSPI device (using it as QuadSPI):Why is it not possible (not supported) to use OCTALSPI also as a regular SPI?Datasheet states that "Single-SPI" is possible - but it means actually: "Single-Lane-SPI"...
About SPI simplex communication.
This question is about SPI simplex communication.Is there any sample code that realizes SPI simplex communication only by register operations?Also, is there any sample code that uses HAL or LL?I would like to know both cases of sending and receiving....
