Posted on January 05, 2013 at 01:51 I'm trying to implement PWM on TIM4_CH4 with output on PD15 using only low level register writes as I don't much care for all the high level functions provided. However, I tried to convert the functions to the...
Posted on January 04, 2013 at 09:13I want to use TIM6 and TIM7 together . TIM6- Update Event - 2MHz priority 0x10 TIM7- Update Event - 1MHz priority 0x00 when I closed TIM6 , TIM7 is running normally and toggling LED from PD14 but when I enabled T...
Posted on December 13, 2012 at 05:05I've built a small breakout board for the STM32F373CC:http://ebrombaugh.studionebula.com/embedded/stm32f373breakout/index.htmlI was hoping to be able to use BOOT mode to load it up via the USB device port, but I c...
Posted on January 04, 2013 at 16:58Ok, I'm confused.. according to the docs I should be able to program TIM4 as a PWM with unremaped output on PB9. However, the Timer API call TIM_CtrlPWMOutputs() has an assert which indicates that TIM4 isn't suppo...
Posted on January 02, 2013 at 12:00Hi All,is this normal ? Using 103F along with ST USB CDC Libs on my board and it seems that the USB driver on the PC negotiates a new COM port for every new board i connect to the PC.Normally this is not a problem ...
Posted on January 03, 2013 at 05:56Hi, I have an STM32F4 discovery board and I want to access SD card via SPI. The reason why I want to access Sd card via SPI is that the breakout module that I have has an SPI interface. I have looked on the interne...
Posted on January 02, 2013 at 15:55Hi, is there any possibility to change the polarity TX and RX of USART5? I.e. normally idle state is high, startbit is low. We need (due to bad specs of a foreign device) the opposite polarity (software only soluti...
Posted on November 05, 2012 at 15:06Hello, I read stm documentation on how to enter a microcontroller into dfu mode Iam using stm32f105, and below are the steps that i did 1- Boot0=1, Boot1= 0 2-PD6 = PA10 = PB5 = 0 3- make reset 4- connect the boar...
Posted on January 03, 2013 at 11:46Hi <3 Happy New Year 2013 <3 I want to implement PLL (Phase-locked loop) in STM32F4 Descovery Card The Goal is to control output system frequency to be equal to the input frequency., to eliminate the noise eff...
Posted on January 02, 2013 at 15:29Hello experts, I'm using stm32f4 discovery board. I have connected an interrupt line from a RTC chip to PA1 of my board. The RTC chip gives interrupt signals each 1 second. The way I enable interrupts is as follows...
