Posted on October 07, 2012 at 14:21Hello :)I have a little project using a stm32f4 which receives usb data from the pc using the cdc classes (2048bytes @ 60fps) and then draws them to a Plasma dot matrix display.I have it all working ok :) The probl...
Posted on November 04, 2012 at 14:31 I think it's impossible. I suggest other solution : using external logic IC such as 7408 to create a logic expression (Button 1) AND (Button 2)AND....AND (Button n) and it's output connected to EXT0 pin. And in ...
Posted on November 03, 2012 at 12:38 Hi, I connect SD card to the stm32f0 discovery. I use the pin GPIOB pin 13, pin 14 , pin 15 use to alternate function. The configuration work partial, sck and the MOSI work but the program stop to run whe...
Posted on November 02, 2012 at 23:24 Hello, I use this example code below to get an ISR from GPIO PA0. My hardware is the STM32L152 at board STM32L152D-EVAL. ( http://www.st.com/internet/evalboard/product/2517jsp) So I have only one ta...
Posted on November 02, 2012 at 18:18I am having difficulty compiling the Demonstration Builder example code. I am using MDK-ARM (Keil) with the 256k license but the code is 265k when linked. I read the app note to disable modules but when I tried ...
Posted on November 02, 2012 at 19:31Hi, just thought I would share these results. I've tried to benchmark F30x opamp voltage and current noise density using F3Discovery with an external feedback network connected to a Tektronics MSO4054 oscilloscope...
Posted on November 02, 2012 at 14:51Hello guys, I have been messing with interrupts recently and I have hard time to find in the manuals how the priorities actually work. I have seen the priority groups and priority values. If I understood it proper...
Posted on November 02, 2012 at 07:54I need some help setting up I2C connection to LIS302DL or a generic I2C accelerometer. I need some code examples to get the accelerometer working. Thanks in advance.
Posted on November 02, 2012 at 04:04Dear Friends,I would like to use more than one pins PA0, PB0, PC0 for external interrupt 0, for detecting 3 buttons. I tested with PA0 and it's working well but I want to expand more PINS in similar interrupt. Doe...
Posted on November 01, 2012 at 18:35I have a peripheral bursting 8-bit parallel data at 56MHz gated by a data valid signal. Can the STM32F4xx support peripheral to memory dma at this rate? What is the max rate the STM32F4 can handle dma requests? ...
