Posted on September 04, 2013 at 10:39Hi I'm trying to create a dfu image in TASKING for stm3220G-EVAL. For bootloader I'm using ''STM322xG-EVAL_USBD-FS'' from the STM32_USB-Host-Device_Lib_V2.1.0 library. The binary templet example in STM32_U...
Posted on September 05, 2013 at 10:22From example code given in STM32F2 , I used RTC example & use it with LSI.I have 3V on Vbat pin. I found that when VDD gets removed LSI oscillator gets off also, even if Vbat is present. Is it property of LSI or ...
Posted on September 03, 2013 at 12:07Hi, I would like to ask, what is necessary to make when I configure a input channel as a cascade 32 bit counter, using a master/slave timers as counters, and then when I need to use this input channel as a 16 bit...

Posted on August 30, 2013 at 03:17hi guys i'm new to stm32, i got a problem that i used sdio and fatfs to test maximum speed of write sd card, its only around 330kb/s but when i try to use sd card reader its up to 2mb/s, so i want to figure out why ...
Posted on September 04, 2013 at 18:14I'm trying to flash a custom bootloader to one of these devices: http://www.mikroe.com/mini/stm32/, and they seem to have protected their bootloader. I'm using an STM34F4discovery board for SWD, and OpenOCD (0.7...
Posted on September 04, 2013 at 22:45Hello everyone, I'm trying to transfer 2 bytes using SPI in master mode and DMA. Additionally I have to set and reset CS signal by software. CS signal is low before starting transfer and is high after transfer.So...
Posted on September 04, 2013 at 21:37Hi,For my project I need additional RAM, is it possible to add memory to the STM32F407VG (in the STM32F4-Discovery Board) using the FSMC interface?
Posted on September 03, 2013 at 17:15Hi, i'm working with a STM32F207VGT and i dont achieve to wake up my board from STOP mode with the RTC. The RTC is configured with the LSI because the external crystal for LSE is not mounted. I have read another ...
Posted on September 04, 2013 at 08:22My platform's MCU is STM32f205. I try to modify TIM10_PWMOutput example from STM32F2xx Standard Peripherals Firmware Library to generate one PWM signal by using TIM10_CH1function of pin PB8. But it doesn't work?...
