Hello everybody,
I have interfaced a master board with a slave board and i am sending a buffer from the master and reading it on the slave using RX interrupt handler (internal interrupts) to pass the data from SPI to the task.
The problem is that the interrupt is excuted only one time and then...
Hello everybody,
I want to communicate two efm32 mcu via spi.
I started with simple UART interrupt driven and then polling and I was able to receive data.
But when i switched to the USART (adding CLOCK), i couldn't receive the data in the slave mcu.
Could any one explain me what am I missing ?
Hello everybody,
I have a problem in connecting two DAQ(which mesures voltage) in parallel, both with a resistance. when i connect the first DAQ, it gives me the right voltage which is 110 mV. but when i connect the second DAQ in parallel with the first DAQ, the second DAQ gives me 110 mV and...
[Moved]Store and Forward FIFO
Does anybody has any idea how to organize different memories into a unique FIFO using software??
I need to store data in this FIFO and then read from it
I need to know how to organize my memories into a unique fifo. and yes dma is used to store data into the flash , it is said in the microcontroller refernce manual.
yes dma is used with flash. can someone please tell me how to organize my memories as a unique fifo cause it is the hardest work concerning the store and forward!!
I really need to know what is wrong with my call back function??????
this is my DMA config :
void SetupDma(void)
{
CMU_ClockEnable(cmuClock_DMA, true);
/* Initialization structs */
DMA_Init_TypeDef dmaInit;
DMA_CfgChannel_TypeDef WriteChannelConfig...
i've read the µp refernce manual and the DMA is used to transfer data into both SRAM and FLASH and it is preferable since the project that I am working on is a wireless project so we are talking about low energy application. the primor memory target is the SRAM and then an external FRAM and...
hello, Yes I've seen this link but this fifo is about widening your USART communication buffers but I am trying to organize my three memories as a unique FIFO and use the DMA to transfer the incoming packets for this FIFO and then forward them from this FIFO.
So the DMA configuration will be...
hello everybody,
I am working with the efm32 microcontroller and I want to store data into SRAM and FLASH memories. In order to do so, I have to organize them into a unique FIFO buffer and then use DMA in order to store the incoming packets from Wireless Sensor Network.
Does anybody has an...
I wrote a C-code describing an SPI driver for a FM25CL64 ram memory to interface it with a EFM32GG330 microcontroller. But when debugging, i found a problem reading from status registers or from memory array. In fact, they always return zero even if i write something on them and then read it ...
