Posted on December 29, 2011 at 21:37I have a MCBSTM32 board which uses the STM32F107 and includes a CS42L52 audio CODEC chip on board. I'm trying to create a 12 MHz clock input for the CODEC using TIM3 from the STM32. So far I have succeeded in gene...
Posted on December 16, 2011 at 13:12Hi all, I am trying to program the discovery board of stm32f4 using SWD via the Cn3 connector. Does anyone have any experience in that.. Arun
Posted on November 16, 2011 at 15:11Hello, I try the examples about PWM input form st.com, but it works only for big frequency signals. (like it is said in readme.txt). What should I change with settings TIM4 for example, to be able to check the low...

Posted on December 27, 2011 at 08:50I'm debugging on an Olimex STM32-P103. I think I have the PLL set up at 8 times the 8Mhz crystal. If so, then instruction timing is pretty poor. Here's my loop:ldr r0, =portcldr r0, [r0]mov r1, #0x80mov r2, #0lo...
Posted on December 29, 2011 at 09:10I downloaded the IAR EWMARM V6.30 which support STM32F4 series. But my IAR J-link doesn't support this cpu and I can't download and debug the code. Anyone can tell if I need to update the J-link and how? Thanks!

Posted on December 27, 2011 at 17:34Hi everybody. I've just a little question : does anyone knows if the internal temperature sensor of an STM32F107 can be read with ADC2. In the reference manual it's written ''The temperature sensor is internally c...
Posted on December 28, 2011 at 02:30Hi, first of all sorry for my english but I hope you will understand me.Here is a TIM1 configuration form DSO nano project. I've rewrited it to more readable format:TIM1->PSC = 30;TIM1->ARR = 35;TIM1->CCR1 = (35+1...
Posted on December 26, 2011 at 18:42I want to generate a signal of frequency 250 kHz with a duty cycle of 50%. after 100 cycle the output has to be low continuously until next fifty cycle and again the trend is to be continued. Can anyone suggest me...
