Posted on July 01, 2013 at 12:55I have just created my own SDIO library for SD cards. It works pretty well but i noticed one issue with SDIO interface. I use STMF4 device clocked with 168 MHz. At 168 MHz speed the maximum SDIO clock frequency is 24 ...
Posted on July 04, 2013 at 02:16And how should I configure this pin?MISO is Input Pull UpCLOCK and MOSI are Alternate Function Push Pull CS is Output Push Pulland CD is ??????????? #sdcard-spi-cd-cs-mosi-miso-clock
Posted on June 21, 2013 at 18:47Is possible to create a file in the SDCARD using only this function?Consider that the SDCARD was recognized. Mode SPI.SD_CD => PB7SPI1_MOSI => PA7SPI1_SCK => PA5SPI1_MISO => PA6 #spi-sd-card-mmc-stm32f103
Posted on July 03, 2013 at 22:30Hello, I wonder if there is any predefined protocol for In Application Programming of the application from ST available. I am looking something similar that does avrdude AVR109 for AVR controllers. I would like to sta...
Posted on July 02, 2013 at 22:09Hi,I am working in a USB Device project. The idea is plugging the device in the PC via USB cable in order to mount a drive unit. Data is storaged in a SD card through SPI interface. I am using STM3210C-Eval board and ...
Posted on July 02, 2013 at 08:44Hello I am using IAR embedded workbench tool and STM32W108XX device for development purpose. When I program it I got error message as No reply received.. Error while initializing interface. Please help me as...
Posted on July 03, 2013 at 01:44Hi all, i'm using STM32F407 with 12MHz ext. crystal with 168MHz system clock, i use demo for STM32F4Discovery, i configured Timer4 and Timer8 in same way, specifically: ARR=1, PSC=0, CKD=0, and i'm measuring 42MHz o...
Posted on July 03, 2013 at 10:29Which IRQ do I need to use ? I don't see any IRQ related to TIM9 at stm32f4xx_it.h.TIM8 can also do PWM input - which IRQ do I need to use there ?void TIM8_BRK_TIM12_IRQHandler(void); /* TIM8 Break and TIM12 */v...
Posted on July 03, 2013 at 06:21Hello, I'm on stm32f3.As far as I know, comparators on the device is very fast so it's very suitable to detect short circuit and over current condition in 50 ns. but most of shunt resistor has very LOW value. so it sh...
Posted on May 28, 2013 at 22:42 Take a look at the video below, which shows Linux, in its uClinuxform, running on the STM32F437 microcontoller: http://www.youtube.com/watch?v=_uO8KfhfY2Y&feature=youtu.be The novelty of this con...
