Posted on January 01, 2012 at 22:58When I use DMA to trasfer data from memory to SPI2 everything works well util I try do another trasfer, then I reload NDTR register I try enable DMA, but nothing happens, there are no errors in setatus register, ju...
Posted on December 19, 2011 at 00:07Hello. I have problem with upgrading program in my own bootloader. When procesor is not read-out protected, everything is going ok (verify says ok). Problem occurs when I set <Read-Out Protection> in RFlasher7 (u...
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...
