##### Peripheral State and Errors functions #####
===============================================================================
[..]
This subsection provides functions allowing to
(+) Check the DMA state
(+) Get error code
◆ dma_resume_before_using()
void dma_resume_before_using |
( |
dma_handle_t * |
p_dma, |
|
|
bool |
init_flag |
|
) |
| |
resume dma regs before using if just waked up from sleep /only need to clear sleep_flag if on initial or deinitial state.
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA module. |
[in] | init_flag | true: use in init function or deinit function fault: not use in init function or deinit function |
- Return values
-
◆ dma_set_renew_flag()
set the flag if DMAn has been used before sleep
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA module. |
- Return values
-
◆ hal_dma_get_error()
Return the DMA error code.
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA Channel. |
- Returns
- DMA Error Code
◆ hal_dma_get_state()
Return the DMA hande state.
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA Channel. |
- Return values
-
◆ hal_dma_resume_reg()
Restore some registers related to DMA configuration after sleep. This function must be used in conjunction with the hal_dma_resume_reg().
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA module. |
- Return values
-
◆ hal_dma_suspend_reg()
Suspend some registers related to DMA configuration before sleep.
- Parameters
-
[in] | p_dma | Pointer to a DMA handle which contains the configuration information for the specified DMA module. |
- Return values
