Function Documentation
This function checks the availability of a SPI MIDI port as configured with MIOS32_SPI_MIDI_NUM_PORTS
- Parameters:
-
[in] spi_midi_port module number (0..7)
- Returns:
- 1: interface available
- 0: interface not available
- Note:
- Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions
Here is the call graph for this function:
| s32 MIOS32_SPI_MIDI_Enabled | ( | void | ) |
- Returns:
- != 0 if SPI MIDI has been enabled in MIOS32 bootloader
| s32 MIOS32_SPI_MIDI_PackageReceive | ( | mios32_midi_package_t * | package | ) |
This function checks for a new package
- Parameters:
-
[out] package pointer to MIDI package (received package will be put into the given variable)
- Returns:
- -1 if no package in buffer
- >= 0: number of packages which are still in the buffer
- Note:
- Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions
Here is the call graph for this function:
| s32 MIOS32_SPI_MIDI_PackageSend | ( | mios32_midi_package_t | package | ) |
This function puts a new MIDI package into the Tx buffer (blocking function)
- Parameters:
-
[in] package MIDI package
- Returns:
- 0: no error
- -1: SPI not configured
- Note:
- Applications shouldn't call this function directly, instead please use MIOS32_MIDI layer functions
Here is the call graph for this function:
| s32 MIOS32_SPI_MIDI_PackageSend_NonBlocking | ( | mios32_midi_package_t | package | ) |
Here is the call graph for this function:
| s32 MIOS32_SPI_MIDI_Periodic_mS | ( | void | ) |
This function should be called periodically each mS to initiate a new SPI scan
Not for use in an application - this function is called from MIOS32_MIDI_Periodic_mS(), which is called by a task in the programming model!
- Returns:
- < 0 on errors
