Posted on March 10, 2015 at 14:34Hi, I'm using the STM32F411RE Nucleo board and I would like to generate a 25 MHz square wave by using the output compare of timer3 in toggle mode. Timer is configure as follow : TimHandle.Instance = TIM3; TimHan...
Posted on March 10, 2015 at 15:07Hello,I am running a boot loader and main application on an STM32F429. I am just getting to know how to use the ST Cube v1.4 and I have the following question:I have set up the IWDG in the boot loader and I wanted t...
Posted on January 23, 2013 at 03:19Dear colleagues, I'm planning on using the 32.768kHz LSE timer, and I would like to confirm that this timer is actually built into the STM32F407 I'm using (on Keil board, MCBSTM32F400). There's no clear docume...

Posted on March 09, 2015 at 17:56I can't understand how come TIM1 frequency is 42 MHz. Here is my config: 12 MHz HSE -> 168 MHz PLLCLK (MCO/4 = 42 MHz, checked) APB1 prescaler = 4 APB2 prescaler = 2 so TIM1, as it clocked from APB2 x 2 frequency sho...
Posted on January 26, 2015 at 14:48 Hi, It's already a few weeks I'm trying to bring up a solution of the USB Host via USB HS module with internal FS PHY. The same code works fine if I use OTG_FS module, once I pass to OTG_HS I'm starting ...
Posted on March 08, 2015 at 04:10I need to read the flash, add 1 then flash back to same address, so that I can keep track how many time the user use the device, I use: ~~~~~~~~ FLASH_Unlock(); FLASH_ClearFlag(FLASH_FLAG_EOP | FLASH_FLAG_OPERR | ...
Posted on March 06, 2015 at 20:29I'm using Keil on an stm32f4xx with 10ns read/write sramI have configured the FMC with a data ready of 2 HCLK (my speed is 180 Mhz) so that is 90 Mhz, which is slower than the rating of 100 Mhz of the SRAM, however t...
Posted on March 09, 2015 at 10:02Hello, I am using STM32F3 Discovery kit. I need to calculate logarithms and exponential function (e^x). I cant find these functions anywhere. Are they in any libraries from ST? Thank you for answers
Posted on February 02, 2015 at 18:52 I'd like to display the characters on the ''GUI_Font20_1'' font above I have modified the ''Hello World example (STM32Cube_FW_F4_V1.4.0\Projects\STM32F429I-Discovery\Applications\STemWin\STemWin_HelloWorld) ...
