Posted on November 11, 2013 at 10:33Hello, I am working with STM32F4 Discovery with FreeRTOS and summon arm tool chain.I am sending ADC data over serial Port using USB serial communication.I have write code to get ADC value in continuous conversion...
Posted on November 12, 2013 at 04:01 HELP!!!! I've been banging my head against my keyboard and I can't find what's wrong with this code: /********************************************************* **** INITIALIZE TIMER AND PWM ...
Posted on November 12, 2013 at 22:41Hi All, please somebody help me to write this c code into asm: void EXTI9_5_IRQHandler(void) { /* Clear the EXTI line pending bit */ //EXTI_ClearITPendingBit( EXTI_Line8 ); EXTI->PR = EXTI_Line8; NVIC->I...
Posted on October 03, 2013 at 04:13Hi, I'd kindly ask if anyone can point me to robust uart example, possibly with interrupts, dma and hardware flow control... I also wonder how flow control affects other code and functions ? Thanks in advance, rega...
Posted on July 05, 2013 at 15:12Hi,I didnt find nothing in the datasheet refering the data update rate of the calculations that STPM01 do. Do any one knows? I gues that it is 16,66ms but I am no sure.Bye
Posted on November 11, 2013 at 14:18I have just ported one of my systems over to the STM32F4Discovery board. It is a small OS + TCP/IP. However, I stumbled on a few things: I need to have a 8 khz interrupt for audio sampling. I think I have clocks O...
Posted on October 03, 2013 at 21:20Hi Folks We are porting a complex algorithm from the PC into the STM32F407 and we are testing it on a large test file (15000 items long) which I have include in a .h file in the form const int testdataA[15000] = { ...
Posted on November 08, 2013 at 17:12Hello everyone, I have a product based on an STM32 and a SPI flash NOR memory. I store some data inside the flash NOR, then I read them back through USB. Sometimes (very rare, but happens ..), I get a few corrupte...
Posted on August 21, 2012 at 04:45Hello, I am have been using an external SRAM with the STM32F207. The SRAM I am using is the Cypress CY62167EV30, a 16-Mbit ( 1M x 16 / 2M x 8 ). The SRAM is used to store a captured image and allow for manipulation...
Posted on November 11, 2013 at 20:46I have fried 2 of my 3 stm32F4 discovery boards. Before I even touch the third one I want to understand more about the power subsystem in these devices. I've been reading the datasheets (for the chip, the ref man...
