Posted on April 03, 2012 at 20:12Hello at all, I have to mesaure the delay between 2 signals that I have in input to the microcontroller. I saw the example of the PWM input. I supposed to use an OR gate to have both front to the same pin but I think...
Posted on April 04, 2012 at 07:04STE100P how to set PHY address?Hello. Im trying to using an STE100P PHY ethernet chip (with ST32F217 MCU). In the datasheet for STE100P i see an description for bits 7~3 PAD4:0 in PR20- XMC, XCVR Mode control registe...
Posted on April 03, 2012 at 13:44Hello all.I need to quickly learn how to use the Ethernet on the STM32F217 MCU. 1. I need to be able to setup a webpage that is shown with on board measurements. 2. I must also be able to download and upload data/fil...
Posted on April 04, 2012 at 13:55Hello, I want to use DP83848CVV as Ethenet PHY with STM32F207ZET6 in RMII mode. In Schematics (STM3220G_EVAL),there is some resistor of 51 Ohm in between of signals (RMII_REF_CLK,RMII_TX_EN,RMII_TX_D0,RMII_TX_D1,RMI...
Posted on April 05, 2012 at 07:39Hello, reasently i changed ide to iar and i getting strange problems: i have working code developed in atollic and tested on my discovery boards, but then i use same code on IAR, it just doesn't work. Like touchscre...
