Posted on October 25, 2011 at 20:02Hi all,I have a strange problem using Timer1 in Output Toggle mode. My objective is to generate square waves of different frequencies using the same timer. I've based my code on the 'TIM_OCToggle' example in the St...
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 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 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 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? ...
