DMA ethernet descriptor OWN bit issue
Im using stm32f207 HAL library, LwIP stack with RAW api, no RTOS for an UDP server implementation. Server is receiving frames by polling way because of client nature demands. Client is constantly asking server for reading mcu inputs and asking for wr...
Problem with FreeRTOS ISR Task Notification
I am using Nucleo F411RE dev borad. When I using the FreeRTOS, I found that the xTaskNotifyFromISR always stuck.my handler function as below and I can enter it normally.the program stop at -------------------------------------------------------------...
Ethernet DHCP and static IP mode
Hi allCurrently, I am working on a project in which I have to design an application in such a way that it should support DHCP and static IP mode based on user choice. And this would be in FREERTOS. Users can back and forth between static and DHCP mod...
LwIP pbuf components and memory use for stm32f2 mcu udp server implementation.
I'm trying to understand the documents (having in mind this stm32 document: AN3384), stm32 examples and comments on some source files from this stack in order to choose the correct options for my application.According to the literature I see there a...
Is the stm32 USB stack support Bulk transfer?
I want to perform a bulk transfer from the STM32 device to my host device. Is stm32 USB stack support it support.
STM32G0 issue with USB-C CC 5.1k pull down
Issue is with STM32G071KBU. We are using PA8 as a PWM output and the internal 5.1k pull-down for USB-C charging features is causing problem. We would like the output to be "hi-z" when the power is removed like the other gpio.During the run-time, PA8 ...
Does anyone know of an example showing SPI implemented with DMA on freeRTOS? I was not able to get this running. When I check the data variable in DMA2_Stream0_IRQHandler, it is always 0 when I expect it to be 1. I'm using the STM32F407G DISCO.
I have SPI set in Master Receive Mode Only and my code does work when not passing data to DMA.
What kind of Ethernet controller errors could trigger the HAL_ETH_error_callback function?
I'm working with stm32f207zg ethernet based project with LWIP stack, no RTOS and using HAL library. I have an udp server application implemented and running over there. It's talking with a python udp client. Not much data bytes on the udp transmitted...
Why do i get different results when calculating FIR with DSP math functions
Hi,My Controller is STM32G473RE . Sample rate is each 2.8 ms .I have created a filter with mathlab which presented me with plain C code.This code does exactly what i want and gives the expected results.int16_t input[3100]={4582,4581,4573,.... double ...
