Posted on June 28, 2012 at 16:39Good day everybody !I have two strange problems with GPIO in STM32L151CBU61) This code I compile in Keil. Using an oscilloscope I see the time ports switching. Why PB7 switches slower than PA5 PA11 ? HS...
Posted on June 29, 2012 at 10:24Hello everybody, I begin with CortexM4 STM32F4 on a keil developpement board (MCBSTM32F400) I try to use USART1 in a very simple mode. I take a look to example and discuss forums. My config seems to be good but no sig...
Posted on June 29, 2012 at 11:36Are there signed ST Link (STM32F4-Discovery) drivers that work with Windows7/8 64 bit?When I install the driver (downloaded from the ST site), it does not complain.However, the device as a yellow question mark against...

Posted on June 28, 2012 at 17:48 STM32F4 TIMER 1 PWM1. Please can someone tell me how to enable channels 1, 2 and 3. Channel 4 is fine generating a PWM at 0..100% at 20Hz. I know channels 1..3 hardware is different - just can't figure out what t...
Posted on June 28, 2012 at 19:38How can I configure PWM on TIMER2 (CH3 and CH4)? I would like to configure CH4 in other Channel of the DMA, but looks that only run on Channel 2. /* Configuracoes DMA */ DMA_DeInit(DMA1_Channel2); DMA_InitStructure....
Posted on June 28, 2012 at 01:33 Hello everyone, Did anyone notice that STM32 with an internal HSI at 8MHz cannot be used in proximity to an embedded GPS antenna? The 8MHz internal oscillator happens to have the 197th harmonic close to L1...
Posted on June 28, 2012 at 12:38Hi, I am trying to get a better understanding of the timer hardware for the advance control timers. In section 14.3.1 of RM0008 (Rev. 14) it states:- ''The auto-reload register is preloaded.Writing to it or reading fr...
Posted on June 20, 2012 at 23:19hi.i am using the STM32F107VC board from IAR i have some example code for CAN but in my Board they used the PD0 and PD1 for CAN i dont know how to remap it in my code. i have 2 board and i want to sent data between 2 ...
Posted on June 27, 2012 at 01:07I was looking to use the STM32F4 Discovery board as an output device which requires a significant bandwidth from the supporting PC. I don't have specifics nailed down on this task, 115.2Kbaud might be sufficient but ...
