Posted on November 07, 2012 at 12:53Hi all,One question about EXTI : I have to trigger an external interrupt on pin PC3 of my STM32F405RG.So I have to configure EXTI3 for rising edge, but is it a good practice to enable pull down to avoid false trig...
Posted on November 06, 2012 at 13:12Hi,I was looking for an example of a CAN BUS for STM32F4 can you help?
Posted on November 05, 2012 at 23:47I am thining of to use STM32 to communicate with MIPI interface. Please see the typical format in the attachment. It is hard to do that with PIC18F controller, for data rate up to 26MHz; by-directional TX/RX SPI l...
Posted on November 05, 2012 at 08:21Hello Friends, Am trying to achieve a high baud rate using USART1 - 7.3728Mbps SYSCLK=168MHz APB2=84MHz Now to achieve this baud rate, I need the OVER8=1 (3 bits for Fraction) Using example code, I set the OVER8 b...
Posted on November 05, 2012 at 15:09Hello, I have these information written on the stm32f105 micrcontroller STM32F105 VCT6 Z 990TD 93 MYS 99 045 I have read that it depends on the date code of the microcontroller which is 045 in my case. Wh...

Posted on October 25, 2011 at 20:02Hi all,I have a strange problem using Timer1 in Output Toggle mode. My objective is to generate square waves of different frequencies using the same timer. I've based my code on the 'TIM_OCToggle' example in the St...
Posted on November 04, 2012 at 23:34Hi I am new to the STM32 (using the STM32L151) and I have a question: I need to use ADC1 channel 1 to control the duty cycle of a PWM with DMA (i have this working) Then I need ADC1 channel 2 to control the duty ...
Posted on October 07, 2012 at 14:21Hello :)I have a little project using a stm32f4 which receives usb data from the pc using the cdc classes (2048bytes @ 60fps) and then draws them to a Plasma dot matrix display.I have it all working ok :) The probl...
Posted on November 04, 2012 at 14:31 I think it's impossible. I suggest other solution : using external logic IC such as 7408 to create a logic expression (Button 1) AND (Button 2)AND....AND (Button n) and it's output connected to EXT0 pin. And in ...
