I want to set up an EtherCAT Network, First I have installed IgH EtherCAT Master in my PC (Ubuntu 14.04) and RTAI 4.1 as RTOS
Can I use microcontroller such as STM32 as a slave Thanks in advance

Hey everyone, I'm trying to reconstruct and understand the example code from the an4666 application note. It's really helping me build an understanding but I'm confused about the timers used in the code. I get that the timer is used in input capture to allow a request to be generated every time the clock edge is detected. This request is…(Show moreShow less)
Greetings, I am having some trouble setting up my STM32F407 mcu to be a dual spi slave with dma. What I am trying to accomplish is this : - STM will have two SPI ports configured and will be a slave to both ports (currently I am using SPI1 and SPI2) - SPI1 will use DMA for Tx , SPI2 will use DMA for both Tx and Rx - SPI1 is setup with…(Show moreShow less)
If the SPI in STM32 is used as Slave, the NSS signal effectively gates reception. Software NSS (SPI_CR1.SSM = 1) means, that the NSS signal to the SPI module is *not* connected to the respective NSS pin, rather, that its level is given by the SPI_CR1.SSI bit. DMA has no direct relationship to NSS - transmit/receive DMA is triggered by…
I'm trying to interface my STM32F407 MCU with a peripheral device that has independent DMA/MPU interfaces. The MPU interface is available in two modes (68 and 80) and the data bus width is available in 8-bit and 16-bit mode. The device can be configured to use the same bus for both of the DMA and the MPU, which I believe makes it easier to access…(Show moreShow less)
LOL! Of course it's not 1980 anymore, Mr. Clive, however, I do not think the DREQ/DACK mechanism is something restricted to the 80s era. In fact, many new devices still incorporate the same mechanism for their DMA controller, and I just don't see how a DMA controller is useful without these signals, as the mem-to-mem scenario is very common. Even…
I have: B-L072Z-LRWAN1 Discovery board (based on muRata module) P-NUCLEO-LRWAN1 Pack (Nucleo-64 board with Semtech SX1272 bare chip add-on). I-CUBE-LRWAN firmware pack, v1.1.2 Keil MDK for STM32L0/F0, v5.24a MultiTech Conduit gateway (as part of a LoRaWAN Starter Kit) all of the above purchased/downloaded in the last couple of weeks - so…(Show moreShow less)
The key thing that I'd missed (which is shown in the video) is that the Conduit's LoRa Network Server must be set to Public: With that, I do now see 'JOINED' in the STM32 UART output, and there is something being received in the Node-RED - although it is currently barfing on it ...
Hello, Recently i plan to buy stm32f4 discovery board, This stuff are important for me: 1-CAN network implementation 2-Ethernet 3-LCD When search on STM32F429-DISCO i does not see any CAN example on it,and all of CAN1,CAN2 pins are occupied, the other option is STM32F4-DISCO but this one does not have LCD and its good for audio purpose i…(Show moreShow less)
Hello Dnesh Sadat, Let me also add here some information, which maybe will be helpful to you. Regarding STM32F4 board with features, which you listed (CAN, Ethernet, LCD), this board comes to my mind: STM32F4DIS-EXT. This is in fact extension board for STM32F4 Discovery kit. If allows you to play with LCD and Ethernet. There is no CAN,…
USI LoRa module I-NUCLEO-LRWAN1 - USI® STM32™ Nucleo expansion board for LoRa™ - STMicroelectronics Anyone else ported I-CUBE-LRWAN to the USI Module? What's your experience with the RSSI level vs other SX1272/SX1276 solutions?
The module product page is here: Welcome to " Universal Scientific Industrial (Shanghai) Co., Ltd. Datasheet: http://www.usish.com/pdf/WM-SG-SM-42_Product%20SPEC.pdf There is a link to the ST page for the I-NUCLEO-LRWAN board: I-NUCLEO-LRWAN1 - USI® STM32™ Nucleo expansion board for LoRa™ - STMicroelectronics - but no information at all.
I tested three devices all day long today. All devices are connected to the USART, but the incoming interrupt does not work at all. A program that connects the Lo Ra modules, GPS modules, and wifi modules to USART 1 and outputs the data sent to USART 2. However, the Rx Interrupt does not work at all. Attach the project file.
>>The problem remains unsolved. I'm not sure what the expectations are here, you might have to code things differently and more defensively against errors or timeouts. Coding assistance for HAL projects is limited. Attached is a test supporting 115200 baud on the USART2 (VCP) and 9600 on the USART1 (GPS), please try this and report…
Hi, I have recently purchased a number of NUCLEO-L476 boards but cannot get the USB drivers to install correctly whch are required for both ther STLINK utility and also for System Workbench for STM32. I am using a Windows 10 64-bit laptop with USB 3 ports and have installed the STLINK utility, en_stsw-link004.zip, which includes the relevent USB…(Show moreShow less)
Hi Imen D, Having tried many things including your suggestion it turned out to be a faulty USB cable. The cable was new about six months ago and one of many I had knocking about. Trust me to use the only one that was broken. Thanks for yout reply. Regards FarmerJo
