Functions | |
| static void | portShortDelay (Tuint08 uiLoops) |
| For reporting errors it may be handy to have a function that delays the message for some time. | |
| void | portTrace (Tuint08 uiEvent) |
| The femto OS is capable of tracing its own and your functions. | |
| void | portShowError (Tuint08 uiMessage, Tuint08 uiCallId, Tuint08 uiInfoTask) |
| As long as you are developing, it is useful to keep track of errors that occur (in embedded devices we expect no errors during normal operation) Every error encountered is reported through a call to portShowError. | |
| void | portShowReset (void) |
| The startup code of the Femto OS contains a special call to show a reset took place, this is portShowReset(). | |
| void | portSleep (Tuint08 uiTickBlockMinDelay) |
| Besides the possibility to put the device in a power save mode during idle, the OS supports a low power sleep mode which can be entered for a longer period. | |
| void | portReboot (void) |
| void | portIdle (void) |
| Taddress | portInitContext (Taddress pTaskStart, Taddress pStackTop, Tuint08 uiRegisterCount, Tuint08 uiInterruptStart) |
| void | portSetupTimerInterrupt (void) |
| Specify a function that sets up your hardware so that tick interupts can take place. | |
| Tuint08 | portReadTimer (void) |
| Specify a function that returns the number of subticks passed from the subtick timer. | |
| Tbool | portCheckTimer (void) |
| Specify a function that returns true if the timer interrupt is due but has not yet been executed, and false otherwise. | |
| Tuint08 | portReadAndResetTimer (Tuint08 uiSubTickInterrupt) |
| Specify a function that returns the number of subticks passed from the subtick timer, and simultaneously resets the timer with a new interrupt time. | |
| void | portFSWriteByte (Taddress pAddress, Tbyte bValue) |
| Within this call you must save a byte on the file system at the given address. | |
| Tbyte | portFSReadByte (Taddress pAddress) |
| Return the content of the given location in the file system. | |

Here is the caller graph for this function:
| void portFSWriteByte | ( | Taddress | pAddress, | |
| Tbyte | bValue | |||
| ) |
Within this call you must save a byte on the file system at the given address.
At a file format the Femto FS writes zero's to all valid file locations. Due to the nature of the eeprom, it may be beneficial to invert the byte so that actually 0xFF is stored instead of 0xFF. If you do so, make sure you invert the byte at reading as well. Femto OS assumes this method is the only one writing bytes to the file system and that no other tasks call this method apart from the one that have been granted write access.

Specify a function that returns the number of subticks passed from the subtick timer.
If there has been an unhandled tick interrupt the value must not be reset. Femto OS only calls this method with tick interrupts disabled.

The method should not activate the interrupts yet.

Here is the caller graph for this function:
| void portShowError | ( | Tuint08 | uiMessage, | |
| Tuint08 | uiCallId, | |||
| Tuint08 | uiInfoTask | |||
| ) |
As long as you are developing, it is useful to keep track of errors that occur (in embedded devices we expect no errors during normal operation) Every error encountered is reported through a call to portShowError.
uiMessage contains a 6 bit error message, and uiInfoTask contains (if appropriate) in the first nibble the slot/file or other info and in the last nibble the task number at which the error occurred. You are responsible to get the information off the chip, for example by letting some leds blink. Fatal errors are reported endlessly, non fatal will stop the current task and Femto OS tries to continue operations as far as possible. The system however may crash, hold or reset.

Here is the call graph for this function:
| void portShowReset | ( | void | ) |
The startup code of the Femto OS contains a special call to show a reset took place, this is portShowReset().
Implement it so you can see a reset took place, for example by blinking some leds. This helps you in finding problems with your software since malicious code often gets into a reset loop.

Here is the call graph for this function:
| void portSleep | ( | Tuint08 | uiTickBlockMinDelay | ) |
Besides the possibility to put the device in a power save mode during idle, the OS supports a low power sleep mode which can be entered for a longer period.
You are responsible for waking the device up, since this may be very device dependent. The uiTickBlockMinDelay specifies the number of tick blocks (1 tick block == 256 ticks) that can safely be slept without disturbing regular functions (maximum sleep time). This means that, if the low power sleep stays within that period, no delay task shall wakeup and all other tasks are in sleep mode, provided that cfgUseLowPowerOnDelay == cfgTrue. Otherwise, a sleep mode only comes when all tasks are indeed sleeping, and uiTickBlockMinDelay will be set to 0xFF (i.e. there is no minimum). Femto OS wakes all tasks if you exceeded the maximum sleep time if you set cfgUseLowPowerDelayRelease, otherwise, make sure you do not exceed the maximum sleep time. Please note that you remain responsible to adjust the tick timer yourself using genAddtoTickCount(). If you don't, Femto OS will not notice time has past and may try to go to sleep immediately. If you manually put tasks to sleep this may exactly be what you want however. The function must return.

| void portTrace | ( | Tuint08 | uiEvent | ) |
The femto OS is capable of tracing its own and your functions.
All actions the OS takes are preceded (as early in the code as possible) with a portTrace(byte) call, where byte contains information of the trace point. Specify your code to get the uiEvent off the chip. This must be done as quickly as possible, for you must not uphold the device.
