Posted on June 26, 2011 at 19:08I've built a gas turbine engine, which currently runs on a variety of manual valves/switches to run. What i want to do is to install solenoids into my fuel rings/pump supply, and relays on the switches controlling my ...
Posted on June 27, 2011 at 12:34I am trying to implement EEPROM emulation in the flash memory. I am able to write and read the data from flash. When trying to write the second data it is going to HARDFAULT Error. I m not sure why this happens. Belo...
Posted on June 24, 2011 at 16:49Hello, I have: a STM32F103RC, a fresh 3V Li BATT, a 32.768kHz crystal and my own RTC support library. I works, but... The manual RM0008 (Doc ID 13902 Rev 11), page 454, says:If the input clock frequency (fRTCCLK) is...
Posted on June 28, 2011 at 13:32Are any examples available that demonstrate the use of the STM32F2xx as a USB device on the OTG_FS interface? If not, what resources are available that will ease implementing a mass storage behavior? Thank you, Brian
Posted on June 27, 2011 at 23:53Hello, to reduce powerconsumption during sleep the ADC and DMA are stopped befor the controller is send to sleep mode. What is the correct sequence to start an ADC conversion after wakeup from sleep ? Is the ADC calib...
Posted on June 01, 2011 at 14:45Hello, I encountered problems when trying to send SPI data by means of DMA. It seems that DMA transfer never starts. The sequence of configurations commands is as follow: 1) Enable SPI and DMA clocks RCC_AHBPeri...
Posted on June 27, 2011 at 08:32hi. i am tring to activate 3 chanel as ''6-step PWM generation'' with Dead time and afourth channel as stady 50% duty cycle . for some reason when i activate the Fourth Channel it disraps the other three. why? here is...
Posted on June 26, 2011 at 22:05Hello everybody,I have the following configuration: two stm discovery connecte via SPI, one configured as master and the other as slave. What I do is send SPI commands from the master to the slave, and base on the val...
Posted on June 07, 2011 at 03:07Hi,I'd like to use the STM32F2 series MCU for a new project, but am struggling to find a STM3220G-EVAL. I plan to use this to prototype the product.Does anyone know where I can source one, or have a spare that they ar...
Posted on June 22, 2011 at 00:03I have three questions regarding clock configuration for the STM32F207 / STM32F217: 1. Is there any advantage to using any specific HSE frequency between 4MHz and 26MHz that is evenly divisible by 2, if the goal is t...
