Customized hardware with STM32H723 + LAN8740A for MII mode.LWIP Settings:#define NO_SYS 1#define LWIP_DHCP 1 #define LWIP_NETIF_HOSTNAME 1The DHCP client, UDP and TCP server and ICMP(Ping) are all working fine.But host name didn't show up on DHCP ser...
Hi everyone, i have a requirement where i need to work on the basic PID operations. For that i want to know how i can perform integration and differential equations using STM32F401RE controller. I had a glance through the "math.h" library but now sur...
Posted on June 13, 2018 at 18:36For reasons of testing, I'd like to create a new CubeMX project that uses an old version of a firmware package (To be precise, I'd like to create a projects using STM32L4 0.11 and 0.8.1). The virtual COM port doesn't ...
Hello,I am using dfu-util (v0.11) to update the firmware on my board.It updates correctly, but I get a LIBUSB_ERROR_PIPE error during the "leave".Looking at it with a USB analyzer, a stall is occurring during the GET_STATUS that executes the leave re...
Hallo,is it possible on any STM32U5 device to write only a SPI or other serial stream, that sends data on rising and falling edge?best regards
Hi ST community.I am in the process of building an audio recorder similar to the one in this video (12 bit ADC to Wav via FATFS and SDIO)(223) STM32 Audio Recorder 2: SD Card || SDIO and FatFs stack - YouTubeI followed the instructions of the follow...
I use the STM32F103C4 and STM32F030F4 chip. I design a card with these chips. How I can programmable these chips? If I add SWDIO, SWCLK, +3.3V, and GND pins to the card as a male header, Can I connect the ST-LINK v3 to these pins and program it direc...
Hello,I'm searching for a way to use sector 0 as storage memory but no luck so far.I'm using STM32F401CCU6 and I'm working on a firmware which have to save about 300 bytes in a no volatile memory. For this microcontroller family we have this memory m...
Hi,I'm trying to resolve a issue I see occasionnaly where my USB CDC-ACM device fails to be detected by Windows/Linux host as it is not responding to the first device descriptor request until the system is fully reset.The scenario:STM32U575 (can repr...
Hi,I'm using SPI to communicate between two micros - one F103 (master) and one H750 (slave). The data communicated will be vastly different in purpose and size (e.g. from simple requests to firmware image download) and so the designed protocol necess...
