Posted on March 05, 2014 at 11:32Hey everybody, Is it somehow possible to start/enable/trigger a DMA transfer with the help of another DMA transfer? I'm thinking of the following scenario: - DMA transfer 1 is timer triggered (every 1us) and transfer...
Posted on February 13, 2014 at 14:07I've set up my DMA to transfer 106 half-words via the SPI to a memory buffer. I am quite confident that my buffer size is correct. However, when the transfer actually occurs, it is twice the size I expect (and is ...
Posted on February 07, 2014 at 00:02I'm using a DMA for the first time (on a STM32F427), and am having a bit of trouble: I don't see SCK on any of my four SPIs when trying to transfer data via the DMA (specifically, I've only tried on the Tx side so...
Posted on January 29, 2014 at 13:03Hello,I am new to stm32fx and trying to interface stm32f415 with TI3204 codec, i am operating stm32 in master mode with codec in slave... currently i can not see MCLK being generated by controller i am pasting my c...
Posted on January 19, 2014 at 00:26 I am using stm32f103 to transmit some data over SPI while stm32 acts as slave. I need to use DMA for sending data to the SPI but the corresponding interrupt handler is never called. The code comes in the follow...
Posted on January 07, 2014 at 06:07hi there, I am running an issue about using DMA to transfer data bytes from ports to internal RAM at 12MHZ. I have succeeded in doing so, but I loose first few hundred of data bytes in doing so. Can this could be a...
Posted on January 09, 2014 at 09:30Hi ,I'm trying to use UART4 with DMA Rx Interrupt , and using stm32f103zg microcontroller. but i couldn't find any example project for this in here.Could anyone help me about this matter ? #dma #stm32
Posted on January 07, 2014 at 02:03I have a STM32 discovery board configured in slave mode receiving commands over SPI. When it receives a specific command byte, it activates DMA and sends back a set number of bytes back. I have a print statement at...
Posted on January 04, 2014 at 22:51 Hello, I would like to sample 2 analog channels with 100kHz (STM32F429 disco). I found examples only with one channel. I tryed to edit it, but my code dont work. If I placed breakpoint into DMA2_Stream4_...
Posted on August 30, 2012 at 16:41I have a problem that maybe someone can help with. I've spend the last few days on this and I just don't understand why it's not working. I have a STM32 where I want to send out a buffer over USART 2 using DMA to a ...
