If((pObj->IO.GetTick() - tickstart) IO.ReadReg(pObj->DevAddr, LAN8742_BCR, ®value) IO. This STM32 Nucleo-144 board provides an affordable and flexible way for users to build prototypes with the STM32F446ZET6 microcontroller. * wait until software reset is done or timeout occurred */ If(pObj->IO.ReadReg(pObj->DevAddr, LAN8742_BCR, ®value) >= 0) Caution: In case the maximum current consu mption of the STM32 Nucleo-144 board and its shield boards exceeds 300 mA, it is mandator y to power the STM32 Nucleo-14 4 board with an external power supply conn ected to E5V, V IN or +3.3 V. * Get the device address from special mode register */įor(addr = 0 addr IO.ReadReg(addr, LAN8742_SMR, ®value) DevAddr = addr PObj->DevAddr = LAN8742_MAX_DEV_ADDR + 1 Uint32_t tickstart = 0, regvalue = 0, addr = 0 So that function looks like: // Used in ethernetif.c, 363, static void low_level_init(struct netif *netif) The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. PObj->IO.WriteReg(pObj->DevAddr, LAN8742_BCR, LAN8742_BCR_AUTONEGO_EN) This is simple yet complete WebServer library for STM32 boards running built-in Ethernet LAN8742A (Nucleo-144, Discovery), ENC28J60 or W5x00 Ethernet shields. In the file lan8742.c (driver), I added an extra line for the LAN8742_Init function, around line 190, to set auto-negotiation: // Link did not come up after HW reset. The HAL_Delay mentioned may not be required, though. On this page you will find good information: You may likely need to change your linker script. The default Ethernet GPIOs speed may be too low. The STM32 Nucleo-144 board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontroller, choosing from the various combinations of performance, power consumption and features. You may need to adjust the tour stack/heap size. Memory buffers need to be assigned to RAM that can be accessed by the Ethernet Information about this issue can be found here.
