Posted on January 26, 2012 at 18:17It would seem to me given the way the GPIO pins are mapped to EXTI lines, there is no way to use two pins that have the same GPIO pin number. For example, in my case I would like to use pins A8 and B8 as separate ...
Posted on December 14, 2011 at 20:35I currently have code which runs on the STM32F4-Discovery board and DMA's data from the ADC to a buffer. I am using double buffering, so I can operate on one buffer while the other is being filled. In short, my ...
Posted on January 26, 2012 at 01:28The STM32F10x series of MCU's make use of the ARM Private Peripheral Bus address 0xE0042000 to implement a MCU IDCODE with a revision ID and a device ID. I am using the STM32W, and nowhere in the documentation can...
Posted on January 14, 2012 at 06:08When I try to build an example from ST distribution: STM32F4-Discovery_FW_V1.1.0\Project\Peripheral_Examples\IO_ToggleI get an error complaining of missing stm32f4_discovery.h.This header file is distributed in a f...
Posted on January 25, 2012 at 10:13Hi Can somebody point me in the right direction. I have a peripheral that uses a strange SPI where the data is triggered on both rising and falling edge of the clock. I have heard the i could use a timer as a divid...
Posted on January 25, 2012 at 14:44I am learning how STM32 works. I looked at startup file and starup vector using simulator and example project. And I have question (STM32F105): 1. First dword location of vector is stack pointer and it is initializ...
Posted on January 24, 2012 at 12:00Hello I am looking for a TCP / IP stack that integrates affordable DCHPclient, ''FTP client'' and filesystem. Ported to a STM32F4xx. LwIP not implemented. NicheLITE requires additional packages. Price? Open-source...
Posted on January 25, 2012 at 14:13Hi, i need to perform some field logging with a STM32. I already implemented STM32 as a USB device, but now i need it to act as a Host. Is there any code example to connect the STM32 to a USB Mass storage device?Th...
Posted on January 23, 2012 at 11:02I need all four channels on TIM5 for input capture. According to the data sheet, TIM5_CH1 is available on PA0. On PH10, a signal called TIM5_CH1_ETR is available. Can I use this pin as a normal channel 1 input, or ...
Posted on January 23, 2012 at 17:49Hi,I am trying to get the usart to work on the olimex stm32-p107 board. I setup the GPIO ports and USART, but cannot seem to send, or receive any data. Has anyone has this problem? or any ideas? Here is my code: R...
