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 28, 2012 at 12:30I have a STM32F107VC development kit (STM32F107VC-SK) and I'm trying to get the uIP + webserver example working. I have made some modifications to the code regarding the PHY, as in the example code the PHY is differen...
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 ...
Posted on June 27, 2012 at 22:45Hi all, It seems that debug viewer printf() redirection is working with the latest version of Keil and/or the st-link/v2 embedded in the Discovery kit. The problem is that I am unable to configure properly the flashin...
Posted on June 26, 2012 at 22:41I'm using the standard STM libaries. I'm using SDIO with DMA. It works perfectly when reading up to 511 blocks but as soon as I try and read 512 blocks it stops working. It would successfully transfer 511 blocks then ...
