Posted on January 02, 2017 at 10:11I am trying to get the rate of change of value of the potentiometer using ADC with a timer trigger. So far I have failed. I am trying to measure the change in value of ADC with the Timer trigger of every 100 micro ...
Posted on January 01, 2017 at 11:34I am reading some values from MPU6050 throught I2C and sending data through UART to my pc. sometimes it stops receiving after a while. what might be the reason ??
Posted on December 31, 2016 at 23:25I am working with the STM32F405 microcontroller and I am trying to have a software UART use the same interrupt line (EXTI15_10_IRQn) as other interrupts (for example, button press interrupts). In a perfect world, ...
Posted on December 31, 2016 at 19:56Hi all. The standard SDMMC bus speed is 24MHz which, on the STM32F7 series, is derived from the USB PLL48 clock source / 2. If we want to operate the SD card in High Speed mode, which has a maximum bus speed of 50...
Posted on August 30, 2015 at 16:53Hello,I've been working on a project on my STM32F4 Discovery for a few weeks now and it's been working fine. Today I connected a OV7670 camera and after uploading the code the discovery stopped working after a while...
Posted on December 30, 2016 at 06:03Hi,I am using STM32F4xx based custom board and IAR as an IDE for development. Till now everything works fine, but after adding few lines of code the debugger has stopped working i.e. it is not halting at main(). I...
Posted on December 29, 2016 at 19:44Hi, I have a NUCLEO-F303 board which I would like to use to communicate to two devices using SPI. The NUCLEO would be sending and receiving data to and from the devices via MOSI and MISO.Looking through the datash...
