Posted on July 09, 2013 at 06:23Does anyone know how to disable the JTAG interface on the STM32F4? I want to use the pins for SPI1. For previous STM32s the following was available: GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); This command ...
Posted on July 10, 2013 at 09:51 Hi, I want to try to send stm32l1 in stop mode (in my experiment I want it never wakes up). My code works but the current is not equal to datasheet!! In the datasheet the uC in stop mode is around ~2uA ...
Posted on July 10, 2013 at 10:34Dear all, I'm currently developping under stm32f3 discovery and I'm experiencing difficulties with the IWDG. In a first version of my software, I've been using the std peripheral library to set up the IWDG with the fo...
Posted on July 08, 2013 at 08:44I have interface SDHC card with SPI protocol.If I initialize the card while debugging it worked right. But if initialize it without it then card don't get initialized.What could be the problem, like some timing issues...
Posted on July 08, 2013 at 08:11Hello everyone, I am a new to working wtih ARM processors.I've a STM32F4 Discovery board.I tried to setupSTM32F4 development environment on Ubuntu as stated in this site http://shareee.netne.net/wordpress/?p=83. But W...
Posted on July 05, 2013 at 12:20Hi,I'm very demoralized to study PWM for stm3220G evaluation board. I need a tutorial/example to understand concepts. For example: why does gpio_moder configure in AF (alternate function)? I configured GPIOA1 in my ...
Posted on June 30, 2013 at 17:27I'm using TIM1 to generate a PWM signal of period 1 sec and a varying pulse duty.This pulse undergoes some signal conditioning and then entered to the ADC, worth to mention that nothing happens to the signal's period ...
Posted on July 08, 2013 at 12:54Hi. Just to be sure (because the manual is not very clear in this case..): When the manual states that in single ended zero reference mode the offset is dependend on gain variations it practically means that i can ac-...
Posted on July 08, 2013 at 16:34Hi, we want to use the STM32F106RCT6 in our Future Products. So we Build an prototype an all works fine except the USB DFU Bootloader. We plugged the USB Cable in and the PC didnt recognize the Device. The Markings on...
Posted on July 09, 2013 at 16:58I'm working on getting my ADC to be interrupt driven. From my code below, I can verify that the interrupt is set in the IER (interrupt enable register) for ADC1, and that the EOC bit is high. For some reason, thoug...
