Posted on April 14, 2015 at 13:47I have setup a timer in PWM input mode. It all works well. I have setup the prescaler and period counter so I can measure down to 10 Hz. But if the input frequency is too low (< 10 Hz) the timer will wrap around.If I...
Posted on April 14, 2015 at 21:51 Hello, I have function fifo_read(RxFifo, &rx, 1) which reads byte from FIFO buffer. I want to use this function in two different interrupt handlers. I have declared rx variable as fo...
Posted on April 14, 2015 at 23:01I've made several custom STM32F4 boards.Never any problems, until now, when my JLINK detects my board ONLY, if I press reset button before I press detect device in Keil uVision.When I press download button I got erro...
Posted on April 14, 2015 at 17:03How can I disable RTC 512Hz signal and return PC13 as I/O ??I programed the PC13 as ''GPIO_AF_RTC_50Hz'' to calibrate the 512Hz signal of internal RTC, but now I cant disable it to use PC13 as I/O, The STM32F205 doe...
Posted on April 13, 2015 at 09:08We are experiencing a very annoying issue... we have a portable application, STM32L151, DVdd=3.0 regulated via an LDO, lithium battery. Randomly, the MCU freeze and the nRST does... nothing! We need a full power cycl...

Posted on April 14, 2015 at 04:51I am developing a HID USB with STM32F107, and iam currently using STM32_USB-FS-Device_Lib_V4.0.0. 1. My problem is that i dont understand clearly about USB_DISCONNECT feature in this MCU.2. I see in the library, ST d...
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: ____________________________________________...
