Posted on September 28, 2011 at 08:00some part of my code keeps the speed of motor using encoder. I have an timer interrupt, calc impulses from the motor and find the speed. It works fine in ''download and debug'' (IAR + jetlink). But when I press '...
Posted on November 24, 2014 at 21:35Code is very simple. I have checked it again and again but cannot get the interrupt to trigger. The interrupt does trigger if I use the software interrupt command. Anybody see the bug? I am outputting a 150Hz 3.3V...
Posted on December 04, 2012 at 18:48Dear all,I am looking forward solution of my problem. I have successfully configured CAN driver in loopback mode, but when I want to connect to physical layer (MCP2551 I/C), there is no output on pins.#define CANx...

Posted on February 25, 2014 at 20:36Hello,i'm a beginner in STM32 can someone give me an example of how to use the LDR with STM32F1.
Posted on November 16, 2014 at 17:25 Hi all, For a school project we need to work with theSTM32LDiscovery board. We want to make a kind of plantcare system that reads the temperature and light in analog values. Now we got to the part that we ...
Posted on December 18, 2013 at 23:00I am using a STM32F203IGT6 trying to detect low VDD using the PVD feature. This seems simple, but I cannot make it work. My initialization code is below. I start the peripheral clock set the PLS and PVDE bits (...
Posted on November 22, 2014 at 22:07I am trying to reduce the duration of my critical zones so I am checking which section of the code costs how many processor cycles. I am looking at CYCCNT and it seems as if entering or exiting a method alone cost...
Posted on November 18, 2014 at 11:58Hello,I encounter a strange bug with an ADC acquisition on IRQ. I use an eval board STM32F0308-DISCOVERY. I program this board with Ride7 and the RkitARM. The start code of the application is generated by STM32Cub...
Posted on November 14, 2014 at 15:15Hi I'm new in High frequency PCB design and i want to make my own STM32F439 board , so my question is : should i have any consideration in my design for signal integrity problems when maximum clock is 180 Mhz and ...
