The schemes of a production circuit are given to me from another designer for being analyised. PCB board is a STM32F103VC based circuit.When I was looking at the bootloader circuitry scheme I saw how RS232 bus seems to be connected to the UART1 micro...

When you look at your Nucleo-f207zg board, ethernet stage, you can see: 1. (CN14) RJ45 connector.2. (U11) magnetic-transformer.3. (U10) TVS diodes for diff pair signals.4. (U9) LAN-PHY device. First appreciation:Then you can see that not connected RJ...

I have spent some weeks working on a firmware project. I had other projects on this tab that where clossed. So, if needed I can open the file and Iook for what I need from them. Last time I compiled the project. No errors. No warnings. A bit time lat...

I'm testing and debugging a server application running on a custom board based on LAN8742 and stm32f207zg devices. Server has an UDP version and a TCP one. Firmware is built using LwIP stack (2.0.3 version), Raw api, non RTOS and HAL drivers (1.9.4 v...

I'm checking the default configuration of an ethernet communication project based on STM32F2 microcontroller (RM0033 stm32f207 reference manual). Where the comments I'm gone to do, they could be find on section 28.6.2 (page 881, etc). I think it does...

So, acording to you RTS and CTS signals on my scheme are surelly used for another kind of things. It's using flux control signals for FCSM control..

Hi, Rim. version: 1.12.1Mcu: stm32f207zgDouble click over project icon does not open anything and no message is launched. Click action is ignored. Same is happening when open project from file system option. So I tried with importing a project: It a...

@LCE yes it does, but I had to add more corrections. This register was wrong mapped, but duplex and speed bits mapping are wrong too. MACCR register now is "showing" full duplex. I did it and it was finally solved: /* Section 4: Extended PHY Registe...

Thanks @LCE , I'm worried about this situation. MAC is completely wrong and it is thinking it's in half duplex when not. Even DMA ethernet descriptor status "duplex-mode field" says that it is half-duplex. ST is a great company and has devices used ...

I vote for having more ST literature sources or references about how to configure LwIP options according application needs. This is very important to do correctly specially for memory and pbuf parameters. I don't find any document neither examples ab...
