hello Ti:
I want to send more than 128 bytes of data once
Please tell me how to set ?
In addition, I can not understand about send number or dma.
Follow is my code for send less than 128 bytes of data, it work well
Why the active send number is "length",not icount of DMACTRL.
DMA using can not been understand well, please explain a little more,thanks!
dmaConfigCtrlTxPacket((uint32)(sendbuf),
(uint32)(&(mibspiRAM1->tx[0].data)),
length);
dmaSetCtrlPacket(DMA_CH0,g_dmaCTRLPKT);
dmaConfigCtrlRxPacket((uint32)(&(mibspiRAM1->rx[0].data)),
(uint32)(&SPI_RX_DATA),
length);
dmaSetCtrlPacket(DMA_CH1,g_dmaCTRLPKT);
dmaSetChEnable(DMA_CH0, DMA_HW); //tx
dmaSetChEnable(DMA_CH1, DMA_HW); //rx
mibspiREG1->DMACTRL[0] = 0 << 31 // ONESHOT
| 0 << 24 // BUFID
| 1 << 20 // RXDMA_MAP
| 0 << 16 // TXDMA_MAP
| 1 << 15 // RXDMAENA
| 1 << 14 // TXDMAENA
| 0 << 13 // NOBRK
| 0 << 8; // ICOUNT
mibspiTransfer(mibspiREG1,0);
