Posted on October 14, 2013 at 12:47Hi, I am trying to drive a servo motor(for this case, TowerPro MG90S), so I want to get 50 hz frequency and duty cycle between %5 and %10. My board is STM32F407 Discovery. I tried to change Peripheral Lib example a...
Posted on October 09, 2013 at 15:46Hi all,I'm looking for detailed Timers Information: block schemes, detailed descriptions for every kind o timers, timing diagrams etc... for STM32F3.I've found only general information on http://www.st.com/st-web-u...
Posted on October 14, 2013 at 12:38Hello together,I got an STEVAL-CCM001V2 evaluation board. This Board has an TFT-Display and some touch-keys to control the function of the board. The board has an micro-SD card slot and you could watch pictures on ...
Posted on October 14, 2013 at 11:27Hello,I've some problems with the SPI interface of the STM32F405 microcontroller. I hope someone could help me.I've a F-RAM connected to the STM32F405 via SPI. I'll checked pin connection and GPIO configuration wit...
Posted on October 13, 2013 at 06:46Hi,I'm trying to understand what the ADC_SMPR register is used for.According to Reference Manual we have following control on the ADC conversion time:ADC_CR1 Register:Bits 25:24 RES[1:0]: ResolutionThese bits are w...
Posted on October 08, 2013 at 00:24Hi!how do I findthe number of the first isochronous frame-odd or even? tracing shows, the host can start transmitting with both even and odd frames unpredictable. however, the frame number must be programmed in STM...
Posted on October 07, 2013 at 21:54Hi, I am using the Discovery F3, I am trying to interface with an SPI port device which requires a 32 bit transfer and 8 bits for address, in the data sheet, the data size is between 4 and 16 bits. I would know if ...
Posted on October 06, 2013 at 03:28 I'm using a DIY development board for STM32F405RGT6, with an 8MHz HSE. I've used the clock configuration tool from ST to generate the system_stm32f4xx.c file such that the clock is configured to 168MHz using t...
Posted on February 22, 2012 at 17:14Dear All, I have two separate STM32F103's communicating to each other by SPI. I've configured one as a master & the other as a slave. I'm using DMA to automate the SPI transfer. I've used the ST Library (3.5.0) e...
Posted on October 12, 2013 at 18:48Hello, in fact I've been working on the STM32F3 Discovery Board and I could generate a PWM signal. But there is still something I couldn't understand, which is how to calculate the prescaler value according to the ...
