FreeRTOS+IO Board Support Package (BSP) Description
|
| Hardware | The BSP was developed on and targets the LPCXpresso LPC1769 CPU board and LPCXpresso Base Board. Rev A of the base board was used. |
| Development Tools | LPCXpresso IDE |
| Configuration Files Location | FreeRTOS-Plus-IO/Device/LPC17xx/SupportedBoards/LPCXpresso17xx-base-board.h |
| Port Layer Location | FreeRTOS-Plus-IO/Device/LPC17xx |
Supported peripherals and modes
| Peripheral | Connected To | Transfer Modes Supported | Demo App # |
| UART3 | USB connector on the base board via an RS232 to USB converter. | Polled Rx - Polled Tx - Interrupt driven zero copy Tx - Interrupt driven circular buffer Rx - Interrupt driven character queue Tx - Interrupt driven character queue Rx | #1 |
| I2C2 | OLED and serial EEPROM | Polled Rx - Polled Tx - Interrupt driven zero copy Tx - Interrupt driven circular buffer Rx | #1 |
| SSP1 (used in SPI mode) | 7-segment display and SD card MMC driver | Polled Rx - Polled Tx - Interrupt driven zero copy Tx - Interrupt driven circular buffer Rx - Interrupt driven character queue Tx - Interrupt driven character queue Rx |
#1 (7-segment display)
#2 (SD card MMC driver) |
The demo application also integrates lwIP and FatFS.
BSP specific FreeRTOS_ioctl() request codes
| Request Code | Description | Parameter |
| ioctlSET_SSP_FRAME_FORMAT | The SSP port can operate in a number of different modes, one of which is SPI mode. | boardSSP_FRAME_SPI is the only supported value, and configures the SSP port to use SPI mode. |
