Posted on April 05, 2012 at 18:43My application calls for using an external oscillator (not a crystal) as a clock source. To test this, I have an arbitrary function generator outputting a 50% duty cycle square wave of the expected clock rate. The MC...
Posted on February 12, 2012 at 01:30Hi, I have modified an example project of IAR for STM32L1XX with a new library definition (one file .c and one file .h). In the file .h I have defined a variable that I use in the .c file. The function defined in ...
Posted on April 08, 2012 at 16:18Hello ! I I start working with STM32L151 + Keil + ULINK2 , and met a problem : after some code, likely it was scommand GPIOA->BSRRL=GPIO_BSRR_BS_2;processor stop the debugging, and a can not start a new debu...
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...
Posted on April 04, 2012 at 12:16Hello, I would like to download a C compiler for STM32F207. Where I could find it? I was searching through the forum, but without success. #stm32f207 #c/c++-compiler
Posted on March 29, 2012 at 07:42Hi all,I wanted to know is there any software workaround to compensate for negative ppm values.I am using STM32F100V8 controller. According to the rtc digital calibration manual(attached) you can only subtract the cy...
