Posted on May 03, 2012 at 22:09Hello all, this is my first discussion here. I'd like to write my own software to control USB in STM32F4 device using bulk transfesr in peripheral mode only. I read USB ON-The-Go chapter in Reference Manual thoroughly ...
Posted on May 02, 2012 at 16:31Hi,we are using three STM32F3210E-Eval for about 1 year now. Recently 2 of these boards stopped responding via JTAG. The JTAG interface used is a Segger J-Link Edu. Different J-Links on different PCs have not made a di...
Posted on April 13, 2012 at 13:28Hi, why i have to enable USART1->CR1 |= USART_CR1_RXNEIE; for polling In Example of ST Lib i dont see such thing. I thought for polling i dont need this?
Posted on April 30, 2012 at 08:59Hi all, I have generated a .axf file using ARM DS-5. I want to convert it into .hex file and flash to STM3240G-EVAL board. I tried using arm comiler's 'fromelf' utility and one more tool ''ronetix-gnutools-arm-elf'' ...
Posted on April 26, 2012 at 21:20dear all, I'm working with the microcontroller STM32F207, below there is my function to configure the DMA in order to acquire 3 characters from USART2 and have the interrupt when those 3 characters arrived. Unfortuna...
Posted on May 01, 2012 at 17:29I'm simply looking to have the STM32F4 startup using the HSI clock (at the default 16MHz). How best can this be accomplished (if it's not already default). What clock does the STM32F4 natively startup using? I was t...
Posted on April 05, 2012 at 01:00Hi, I need some ideas on a problem I'm experiencing.I have an STM32F2xx based product (an automotive sensor of sorts) which has just started field testing. The electrical interface to the product is 4 wires - +V, GND...

Posted on April 30, 2012 at 00:58Hi guys.I have been playing with Stm32f4 discovery for couple months.My problem follows like this;I have to take 2 vga images from CMOS camera and store them.I will make some mathematical operations on both images.An...
Posted on March 26, 2012 at 16:03Hi, I not having much success with using the UART (USART1) on my F4Discovery board (STM32F407). I am pretty new to STM32 and Keil (the IDE I am using). Here's my code: &sharpinclude ''stm32f4_discovery.h'' &sharpincl...
