Configure the DMA channel
- Warning
- this function must be called before enabling the DMA channel
- Precondition
- the DMA channel must be disabled to be reconfigured
- Parameters
-
| data | output data |
| dataSize | number of DMA transfers to be performed |
| circularMode | DMA circular mode setting |
| priority | DMA transfer priority |
template<typename DmaChannel >
| static bool modm::platform::Dac4Dma::Channel1< DmaChannel >::hasDmaUnderrun |
( |

|
|
static |
Returns true on DMA underrun
- Warning
- To reset the condition both the DAC channel and DMA channel have to be disabled and and the DMA channel must be reconfigured.

| |
|
static |
Set data to transfer
- Precondition
- the DMA channel must be disabled to call this function
- Parameters
-
| data | output data |
| dataSize | number of DMA transfers to be performed |
template<typename DmaChannel >
| static void modm::platform::Dac4Dma::Channel1< DmaChannel >::setTriggerSource |
( |
uint8_t |
triggerSource | ) |
|
|
static |
Configure the external trigger source
If DMA is used the external trigger mode is always active
- Parameters
-
| triggerSource | trigger source id, please refer to the reference manual |
template<typename DmaChannel >
| static void modm::platform::Dac4Dma::Channel1< DmaChannel >::startDma |
( |
| ) |
|
|
static |
Start DMA transfers
- Precondition
- before starting the transfer the channel must be configured
