Posted on April 12, 2015 at 05:04Hi, I am trying to use UART5 on the STM32F103, 100 pin device. As per documents Tx and Rx pins are PC12 and PD2 respectively. I enabled clocks, initialized the port and when I try send a character (code below) U...
Posted on March 24, 2015 at 02:34I am studying about LIN protocol and its implementation on STM32F107. Also I am new to this microcontroller, can anyone suggest me some materials about this microcontroller as well as the documents about LIN implemen...
Posted on January 01, 2013 at 14:08I want to generate a PWM signal to control a servo motor. The servo has a dead band width of 10?s. I have tried doing this using the '7_PWMOutputs' example. Code so far: ____________________________________________...
Posted on March 13, 2015 at 12:33 Hi! I modified the following program to get a pulse of 5V and 40kHz of frequency. I tried it in an oscilloscope and I get a 4V pulse and 12,8kHz frequency. What is wrong in the code?? #include ''stm32f4xx...
Posted on April 13, 2015 at 15:56Help! I have loaded the STM322xG_EVAL/Applications/FreeRTOS/FreeRTOS_LowPower demo project into my STM3220G-EVAL board. Every 500 msec the red LED flashes to show me that the CPU is waking from sleep but I am havin...
Posted on April 13, 2015 at 17:04 Hello st! Today i bumped into a problem with code generation for encoders in CubeMx tool. I've read all topics on this site connected to timers in encoder modes, but all i've found was only not-working...
Posted on April 10, 2015 at 19:24Hi,I am trying to do semihosting, so that I can print debug messages to the console on Eclipse + OpenOCD.It works except that the printf s take a long time to print. For example if I want to print ''Hello World''. It...
