Structs
| DMAChannel | |
| DMARegisters |
Memory registers for a DMA channel. Section 16.6.1 of the datasheet. |
Enums
| DMAChannelNum |
The DMA channel number. Each channel transfers data between memory and a particular peripheral function (e.g., SPI read or SPI write, but not both simultaneously). There are 16 available channels (Section 16.7). |
| DMAPeripheral |
The peripheral function a channel is assigned to (Section 16.7). |
| DMAWidth |
Constants
| DMA_BASE_ADDR |
The PDCA's base addresses in memory (Section 7.1 of manual). |
| DMA_CHANNEL_SIZE |
The number of bytes between each memory mapped DMA Channel (Section 16.6.1). |
Statics
| DMA_CHANNELS | |
| NUM_ENABLED |
Shared counter that Keeps track of how many DMA channels are currently active. |
Traits
| DMAClient |
