Posted on November 27, 2012 at 06:06Hi , Is there a way to disable/enable external interrupt ?
Posted on November 27, 2012 at 07:39Hello All, I am using STM32F2 series of controller. I want to monitor the battery voltage of my device which is connected to GPIO Pin 3 of port A which has alternate function of ADC1. Here is my code void RCC_Con...
Posted on September 24, 2012 at 10:19 Hello I want to implement an encoder interface in a timer (Encoder Interface Mode). But how do I handle the sliding noise on the rising or falling edge of the A and B signal (see picture)? I wou...
Posted on November 26, 2012 at 13:07Hi fella. I want established a communication between a board stm32f4 discovery and a sensor LIS3LV02DQ by SPI interface. But I don't understand how to configure the clock to sincronize the board and the sensor. I ...
Posted on November 26, 2012 at 21:56Hello,My custom STM32F417 board is connected to a RaspberryPi via SPI2. The RaspberryPi is master, the STM slave. I'm able to receive data from the Rasp and for validation purposes I'm directly sending it back to ...
Posted on November 25, 2012 at 08:52Hello,I work on the STM3240G-Eval and IAR IDE for the first time and I feel a bit lost.I need to be able to capture an image from the camera and store it on a uSD card as a file (preferable JPEG). I would like the...
Posted on November 26, 2012 at 16:14Hello!I try to receive data by I2S3 in slave mode.First of all I tried to program I2S controller and received data by program polling: while(1){ while( (SPI3->SR & SPI_I2S_FLAG_RXNE) == 0 ); SPDiffRxBuffer[T...
Posted on November 22, 2012 at 12:37Hi, I am trying to configure my MCBSTM32EXL board to read from an external temperature sensor. I think I have most the code sorted, including reading from the ADC. However, my knowledge of electronics is weak and ...
