Posted on May 31, 2016 at 05:59Hello everyone! I use to stm32f4-discovery kit. because I was careless, I used PB2( BOOT 1) as GPIO( external intterup line 2). and now I can't load code for chip. what i can do to save it? Thanks for read !!!

Posted on May 27, 2016 at 14:57Is it possible to use baud rate divisor less than 1? i.e. 1/16 - USART_BRR = 0x01I did not find any information about it in STM32F4 RFM. #uart-usart-baud
Posted on May 30, 2016 at 16:28The STM32F7 onboard DAC is only 12 bits. I only need mono audio input. Suppose I drive the left ADC input directly and the right from an op amp gain stage of say x16 and then combine the lowest 4 bits of R with left-...
Posted on May 31, 2016 at 11:19Hello, even the V2.1.1 headers for the F2 family still define HASH_RNG_IRQn for the F20x devices that don't have the crypto feature. The F20x header should use RNG_IRQn. Regards #stm32f20x #headers
Posted on October 31, 2015 at 15:42 Hello there! I have designed a custom board, and what I'd like to do is that when I press the UserButton, a LED lights up.Now, my button is connected to PC0 pin on my STM32F429 controller, and the LED i...
Posted on May 25, 2016 at 13:00Good morning,Whenever I connect my board via usb, the COM LED lights up solid blue and the LD2 lights up solid green. Does this indicate an error (I'm asking because I haven't been able to get the board to work for a c...
