Posted on January 20, 2013 at 18:12I need to be able to store ADC sample on a SD card. the sample rate is 200KHz.Since the buffer size register is limited to a maximum value of 0xffff I decided to use the DMA in a dual buffer mode and ADC in Continu...
Posted on January 20, 2013 at 08:38Hi, I want to measure the preformance of my program,by measuring the execution time of various functions ,as the atollic toolchain dont have functions like : clock_gettime ,that is somewhat accurate to the milli se...
Posted on January 19, 2013 at 02:49I have recently assembled the first prototype of a new board I'm working on for a project and have so far been unsuccessful in connecting to it with the STM32 ST-LINK Utility. The chip I'm using is the STM32F407VET...
Posted on January 18, 2013 at 04:07I automatically feel stupid asking this question, I feel as if I should know this already. I'm not sure the relation volatile, static and other keywords have with variables that you may access all over the place. S...
Posted on January 17, 2013 at 05:20Hi all, I want to use a multiple interrupts on the single EXTI line. In my case I want to handle interrupts of PF8 and PG8 pins on EXTI_Line8 so how can i do that? Do you have any sample code for that? When I initi...
Posted on January 18, 2013 at 18:12First off, please bear with me as I am new to this new environment.....The board I am using is the STM32VL. Looking at the user manual, I found the description of the pins that I want to use for simple output push/...
Posted on January 18, 2013 at 19:01HiI am trying to receive data via USART and then put it on the LCD. I am using the following code.void print_response(void){ uint8_t i, resp[5]; for (i=0;i<5;i++) { while (USART_GetFlagStatus(USART3, USART_FLAG_RXN...
Posted on January 18, 2013 at 17:35Hello all, I am working on a project where I need to implement USB mass storage device. My SD card is communicating with controller on SPI2. As this microcontroller doesn't have the library for SPI so I u...
