Sissors 29:9a41078f0488 3 To add another device some functions/macros need to be defined.
Sissors 29:9a41078f0488 4 The Device folder shows examples of other devices.
Sissors 29:9a41078f0488 5
Sissors 29:9a41078f0488 6 1. In MACROS.h the include to the macro file need to be added.
Sissors 29:9a41078f0488 7
Sissors 29:9a41078f0488 8 2. A <NameOfYourFile.h> file needs to be added, it needs to include the ifdef(target) statement, and definitions for:
Sissors 29:9a41078f0488 9 MODSERIAL_IRQ_REG --- register which enables/disables serial IRQs
Sissors 29:9a41078f0488 10 DISABLE_TX_IRQ --- macro that disables TX IRQs
Sissors 29:9a41078f0488 11 DISABLE_RX_IRQ --- macro that disables RX IRQs
Sissors 29:9a41078f0488 12 ENABLE_TX_IRQ --- macro that enables TX IRQs
Sissors 29:9a41078f0488 13 ENABLE_RX_IRQ --- macro that enables RX IRQs
Sissors 29:9a41078f0488 14
Sissors 29:9a41078f0488 15 RESET_TX_FIFO --- macro that resets TX FIFO buffer, if applicable. If not, something like while(1==0) won't do anything and doesn't generate compiler warnings
Sissors 29:9a41078f0488 16 RESET_RX_FIFO --- macro that resets RX FIFO buffer, if no hardware options, you can also read data until no more data is available
Sissors 29:9a41078f0488 17
Sissors 29:9a41078f0488 18 MODSERIAL_READ_REG --- register where RX data is in
Sissors 29:9a41078f0488 19 MODSERIAL_WRITE_REG --- register where TX data is in (can be same as previous)
Sissors 29:9a41078f0488 20 MODSERIAL_READABLE --- returns true if new data is available in read_reg
Sissors 29:9a41078f0488 21 MODSERIAL_WRITABLE --- returns true if we may write new data in write_reg
Sissors 29:9a41078f0488 22
Sissors 29:9a41078f0488 23 RX_IRQ_ENABLED --- checks if RX IRQs are enabled by MODSERIAL. Only required if the device has no registers that tell which IRQ fired. If those registers are available (LPCs have then), may just be 'true'
Sissors 29:9a41078f0488 24 TX_IRQ_ENABLED --- checks if TX IRQs are enabled by MODSERIAL. See previous
Sissors 29:9a41078f0488 25
Sissors 29:9a41078f0488 26 3. A <NameOfYourFile.cpp> file needs to be added, it needs to include the ifdef(target) statement, and functions for:
Sissors 29:9a41078f0488 27 void setBase(void) --- function that sets _base pointer to point to correct UART, and _IRQ pointer to point to correct IRQ.
Sissors 29:9a41078f0488 28
Sissors 29:9a41078f0488 29 void initDevice(void)--- function that allows for setting registers after everything else is initialized, if required
Sissors 29:9a41078f0488 30
Sissors 29:9a41078f0488 31 bool txIsBusy(void) --- function that returns true as long as long as device isn't done with transmitting
