Hi, All when I power on the U575 eval board, the file system of flash chip come out immediately on my computer as the attached picture. My question is how to read/write the file system from MCU of U575 by firmware? Anyone has the experience or an...
Hi there! I have trouble escaping CAN error passive state on STM32F417VG microcontroller.The goal of my application is to automatically detect external CAN bus baud rate (either 250kHz or 500kHz) then send CAN messages on the bus at the right frequen...
We have product running with STM32L162ZET6 successfully. Because of memory constraints on future developments , we wanted to use alternative part for it. During research, we found STM32H533ZET6 by Hardware engineer.After comparison, we found that arc...
/* add the network interface (IPv4/IPv6) with RTOS */ netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, ðernetif_init, &tcpip_input); while(1){ /* Registers the default network interface */ netif_set_default(&gnetif); if (netif_is_link...
Hi... We are planning to use STM32H503 in our application. Due to size constraints in the PCB dimensions, we are going with internal clock for both MCU & internal RTC.Since, internal clock is used, the frequency given to the internal RTC ranges from ...
Hello, I've been working in a LoRa (not LoRaWAN) network, implementing a master-slave topolgy with NUCLEO-WL55JC1 boards. Currently, I'm sending commands to the master via UART, but I'd like to do this through a web server, so I'm trying to get ether...
The main function code is as follows: while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ loop_cnt++; //HAL_GPIO_TogglePin(LED_GPIO_Port,LED_Pin); if(13 == ((loop_cnt >> 4) & 0x0f)) HAL_GPI...
Hello everybody,This is my first post hope i wll get the answer.I am building a spectrometer for which i am using a stm32f401re board and i need to sample the data coming from a sensor at 250kHz which nearly gives a data rate of nearly 4Mbps so do i ...
Hi,On an Stm32f4 based board, we have the external crystal (8MHZ) mounted. The Firmware however uses HSI clock. Does the HSI drift have an impact on CAN communication with another device over a long period of time(say weeks)? Is it recommended to use...
Hi, I am experiencing a problem on the STM32F411RET6 and STM32F411RCT6 MCUs. When programming these devices I am getting a repeated "Target is not responding, retrying..." message until the debugging session shuts down and exits. I have managed to na...
