Detailed Description
Macro Definition Documentation
◆ __HAL_DMA_CLEAR_FLAG
| #define __HAL_DMA_CLEAR_FLAG | ( | __HANDLE__, | |
| __FLAG__ | |||
| ) | (DMA1->IFCR = (__FLAG__)) |
Clear the DMA Channel pending flags.
- Parameters
-
<strong>HANDLE</strong> DMA handle <strong>FLAG</strong> specifies the flag to clear. This parameter can be any combination of the following values: - DMA_FLAG_TCx: Transfer complete flag
- DMA_FLAG_HTx: Half transfer complete flag
- DMA_FLAG_TEx: Transfer error flag
- DMA_FLAG_GLx: Global interrupt flag Where x can be 1_7 to select the DMA Channel flag.
- Return values
-
None
◆ __HAL_DMA_GET_FLAG
| #define __HAL_DMA_GET_FLAG | ( | __HANDLE__, | |
| __FLAG__ | |||
| ) | (DMA1->ISR & (__FLAG__)) |
Get the DMA Channel pending flags.
- Parameters
-
<strong>HANDLE</strong> DMA handle <strong>FLAG</strong> Get the specified flag. This parameter can be any combination of the following values: - DMA_FLAG_TCx: Transfer complete flag

- DMA_FLAG_TEx: Transfer error flag
- DMA_FLAG_GLx: Global interrupt flag Where x can be 1_7 to select the DMA Channel flag.
- Return values
-
The state of FLAG (SET or RESET).
