I am running LwIP on the STM32F746 using the LAN8742 phy interface. The system works perfctly and i am running MQTT protocol publishing and subscribing all working like clockwork, until i pull the ethernet cable out then it all truns to crap. Does an...
Posted on April 05, 2013 at 14:13Hello everyboby,I'm using KSZ8863RLL chip from Micrel as Ethernet PHY, with STM32F207IG in RMII mode.50 MHz Clock reference is sourced externally by an oscillator.PHY registers are accessed through SMI (with ETH_MACM...
Hello there,Here is my CubeMX version:Here is my L4 libs version: I have noticed some disturbing inconsistencies in the #ifdef include guards generated in the default peripherals code. So far all peripherals has guards like this:#ifndef __STM32L4xx_H...
Hi,I use DMA in Dual Buffer mode to feed QSPI Interface. Now I need to know when DMA starts with second buffer so I can start to rewrite the first one.I was checking static void QSPI_DMATxHalfCplt(DMA_HandleTypeDef *hdma)andstatic void QSPI_DMATxCplt...
Hi all, I am new to USB communication so please forgive my imprecisions. I am using the discovery board STM32F469I-DISCO. I have been able to establish serial communication through the programming port (the port connected to the ST-link/V2-1) using ...
Posted on June 03, 2018 at 19:44Hello. I am developing the device on STM32L433 with the following logic of operation:1) Pressed the button - the sensors are reading (SPI, I2C), data from them are written to the memory card via SDIO + FatFS2) Pressed...
