Posted on October 01, 2013 at 09:58Hello, I am trying to read data from USART using DMA. Receive buffer (DMA_BufferSize) in my code is 4 bytes, but even when 1 byte of data received, MCU is interrupted with Transfer Complete flag (DMA_IT_TCIF1). Giv...
Posted on October 24, 2013 at 21:18Hello, I am new to developing on an STM32L. I'm using IAR Workbench to compile for it using FreeRTOS. I don't seem to be able to be able to get it running using any of the C/C++ functions. I can build a simple task...
Posted on October 18, 2013 at 18:02I need the recommended PCB footprint (sometimes known as land pattern) for the WLCSP63 package of the STM32L151. The datasheet only has the drawing for the package, and I can't find a footprint on the ST website. ...
Posted on October 25, 2013 at 10:06Hi to everybody, I'm new to STM32F303, my ploblem is I'm not able to found a valid example on where is showen how to configure two timers in the way to use the first one to acquire an encoder's pulses and the secon...
Posted on October 25, 2013 at 12:27Hello everyone, I am trying to interface a CCD to STM32f4 discovery kit. I need to generate a clock of 4MHz and toggle couple of pins when the clock is high to to get the output from CCD. I referred some examples f...
Posted on October 21, 2013 at 08:19Hello everyone, Kindly guide me to get this understand and resolve the following problem. I am trying to work out following mode of ADC and DMA to suit my application. But the results are not as expected. -Regular ...
Posted on October 16, 2013 at 18:44I have been trying to us MicroXplorer to generate startup code for the STM32L152RC, but the only thing I seem to be able to configure is the System: GPIO configuration. I can't seem to access any of the other confi...
Posted on October 25, 2013 at 05:54 I'm trying to setup some communications between an STM32L152 series MCU with an ATMEGA The Atmega uses 5V logic high. I read the Datasheet and found that the UART1 RX pin is 5V tolerant on the STM32 so I shoul...
Posted on October 24, 2013 at 16:13Hi there,Lately I'm experimenting with the STM32FXXX. Now I came across a problem when I want to configurate the ADC clock. I want to use the maximum frequency that is possible for the ADC. The manual says that the...
Posted on October 21, 2013 at 16:37Hi Friends...Is KEIL better or IAR for STM32 ? Code optimization, speed compiling, Debugging !!! What do you think about this ?
