Hi everyone,I'm working on a project based on the following STM32H7 LwIP example:https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H747_Disco_M7_ETHIn addition to the Ethernet functionality, I’ve enabled the SAI peripheral with DM...
I managed to create a working example ethernet NetXDuo project for the nucleo-h753zi board based of this guide:https://community.st.com/t5/stm32-mcus/creating-a-dual-ipv6-amp-ipv4-netxduo-udp-application-for/ta-p/570521See my repository here:https://...
Hi,On the keynote speech, I saw that FreeRTOS will be the main kernel.Does that mean that ThreadX will not be offered as an alternative?What is the reason for this change?What about NetXDuo as a middleware?I am quite happy with how ThreadX and its co...
Everything else is working fine.Setup packet with SET_ADDRESS received and processed.Next GET_DESCRIPTOR for DEVICE which is sent back ok I've verified the data written to the Tx FIFO is correct.Correct number of bytes it transmitted but the bytes ar...
Good afternoonI am working on the STM32H755 and am dealing with the retransmissions from my CAN FD periphery. According to the ISO-11898-1:2024 standard, the number of retransmissions should be configurable:"- from 0 (no retransmission),- to at least...
I've got the NUCLEO-G491RE board and have it connected to my PC over the only USB port which is of course also used for the debugger. Both printf() and HAL_UART_Transmit() work to send data to a terminal program on the PC, but I can't use polling for...
I'm setting up the ADC in "manual continuous" mode where hadc1.Init.ContinuousConvMode = DISABLE and then I call HAL_ADC_Start_IT() inside of HAL_ADC_ConvCpltCallback(). I get the first call to HAL_ADC_ConvCpltCallback and calling HAL_ADC_Start_IT()...
On an STM32G4, if an I2C error occurs (e.g. a bus error) during a DMA driven I2C transaction, is the intention that the HAL I2C driver abort the DMA transfer?Starting at line 6599 in stm32g4xx_hal_i2c.c (v1.2.5), I see code in the I2C_ITError functio...
Hello, for my first project with a microcontroller I'm doing a 16 button gamepad USB HID with the aid of ChatGPT. I have no idea of what I'm doing really. I'm Using a STM32f103C8T6 and STLink V2. I made a polling version that constantly read pins an...
Hi,We are currently implementing ADC on the STM32G491 MCU using ADC2, Channel 15, with Vref set to 3.3V.The ADC configuration is as shown below: hadc2.Instance = ADC2; hadc2.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc2.Init.Resolution =...
