Posted on March 31, 2013 at 13:18Once again I feel really stupid. I can't get nested interrupts working.In the attached file there are three functions, NVIC_Configuration(), SysTick_Handler() and TIM6_DAC_IRQHandler().I intend the SysTick interrupt ...
Posted on March 21, 2013 at 08:25Device: STM32F405. Is it possible to use two DMA streams with single request? For example, connect DMA2_Stream0 to channel 6 (TIM1_TRIG) and DMA2_Stream4 to channel 6 (TIM1_TRIG, too). I want to start two diffirent D...
Posted on March 31, 2013 at 01:10Hi. I 'm trying to build a board for a project and I want to use the STM32W for the wireless link. On the STM32W application notes there is a reference design that looks easy to build, but I have problem to find some...
Posted on March 30, 2013 at 22:15Hi, In our system, I have to be able to update the application code. Therefore I believe I need to copy the application to memory location 0x8000000 and then jump to this location...basically a small bootloader of so...
Posted on March 30, 2013 at 17:19Hello, I need to connect 4 Ultrasonic sensors to STM32f4. Basically I need to measure the pulse width on their output. I tried to configure an interrupt with TIM5 (32bit counter) for 4 channels and at each interrup...
Posted on March 30, 2013 at 09:21I have experienced with AVR MCU-8bits programs. When I was begin to AVR MCU, there is an official reference that prepared by Atmel itself for developer to understand what register should be initialed in order to have...
Posted on March 29, 2013 at 20:12Hello!I search evrething about this hardware I have bought (whith two probes & a TFT screen with TouchPad (400x240) who can be an oscilloscope 2 ways. I have no software to work with and I have not found it on intern...
Posted on March 25, 2013 at 11:19Hi everyone!! I'm working on my very first project as engineer with a friend and colleague. We bought th eval board with the f4 and f100 series microcontroller on. We tested our code on both of them and everything's ...
Posted on March 29, 2013 at 13:03Hi, i'm a new user of this board and i have a (maybe trivial) question. Searching on the web i found that there is a ''ITM_SendChar()'' instruction that could be very useful for me, but i can not view its result on m...
Posted on March 29, 2013 at 09:23 Hello, I have been trying to use multiple usarts with receive on interrupts. Some part of the communication takes place between a PC Com and STM, while some communications is taking place with STM to another STM...
