Hi I am currently working on a project where I have to implement an Ethernet Driver. below is my code.I am trying to send ARP packets to my directly connected laptop without expecting response (Rx is not used). Code runs without MAC controller and DM...
I have an STM32F407 and I'm using LwIP + DP83848 Ethernet PHY. I'm facing problems to ping the unit and I don't know why. The pinouts for the RMII settings. Red rings got to the processor. The blue ring shows RESET. It need to be logic 1 (HIGH) for ...
Hello,I am working on NUCLEO-H745ziq board. The board support USB FS. I have to configure USB as CDC in AZURE RTOS . The example are provided for HS , so there is any example for FS CDC AZURE RTOS configuration. I am first time working on this AZURE...
In order to get PWM output to PB5, I configurated the Channel2 of TIM3 to be "PWM Generattion CH2" and the PB5 pin to "TIM3_CH2". Then, the code generated and imported into STM32CubeIDE, the pointer stopped at "void HardFault_Handler(void)" function ...
Hi,I have an STM32L552 MCU (the 1st) that has only two interfaces to the user, one through the USB-C and the other through Bluetooth. I have another STM32L031 MCU (the 2nd) inside the design that communicates with this L552 MCU through UART/I2C. Here...
Posted on March 07, 2018 at 13:01 EDIT: 14/03/2018 https://community.st.com/people/Schwaninger.Hannes found that we need to use RAM_D1 and not DTCMRAM of the memory area. This is not made by default when we use STM32CubeMx to set SPI ...
I am attempting to activate the bootloader mode on the STM32G050J6 (SO8N package). It is unclear to me from the documentation which pins are to be used. Currently, I am using pins 1 and 8 (USART1_RX and USART1_TX in the documentation respectively) as...
The board is STM32H747I-DISCO.I have configured I2C chip (PCA9555) properly, it works in interrupt mode.I configured BDMA for TX and RX, default options.I also have DCache disabled because I know it causes problems on H7.First, there are bugs in HAL ...
Hi. I am currently trying to implement USB headset on my old STM32F407 Discovery board.In USB descriptor I have simple topology with two input terminals, 2 out terminals and feature unit. Also I describe two streaming interfaces (IN and OUT) and one ...
