Function Documentation

void menu_cls ( )

Function to clear the screen via Hyperterminal.

Parameters
None
Return values
None

Definition at line 75 of file menu.c.

unsigned int menu_get_direct_entry ( u32  nUartAddress,
int  nNumberBits 
)

Retrieve keyboard entry of a value via the Hyperterminal connected UART.

Details
In most cases, this function is used to directly populate a register with a value. int nNumberBits equals the number of bits in the register. The value input by the user is capped to the maximum allowable for the given number of bits (e.g. - 6 bits => '64' max)
Parameters
[in]nUartAddress- address of the UART peripheral in the memory map
[in]nNumberBits- number of bits in register populate
Return values
Valueentered

Definition at line 171 of file menu.c.

void menu_print_current_range_menu ( )

Print the current range menu.

Parameters
None
Return values
None

Definition at line 287 of file menu.c.

void menu_print_line ( )

Print one line of dashes across the screen via Hyperterminal.

Parameters
None
Return values
None

Definition at line 159 of file menu.c.

void menu_print_maxim_banner ( )

Print standard Maxim banner at top of Hyperterminal screen.

Parameters
None
Return values
None

Definition at line 88 of file menu.c.

void menu_print_maxim_banner_big ( )

Print large Maxim banner at top of Hyperterminal screen.

Parameters
None
Return values
None

Definition at line 112 of file menu.c.

void menu_print_mode_menu ( )

Print the mode menu.

Parameters
None
Return values
None

Definition at line 269 of file menu.c.

void menu_print_prompt ( )

Print a standard prompt for keyboard input ">> ".

Parameters
None
Return values
None

Definition at line 145 of file menu.c.

void menu_print_voltage_range_menu ( )

Print the voltage range menu.

Parameters
None
Return values
None

Definition at line 308 of file menu.c.

u8 menu_retrieve_keypress ( u32  nUartAddress)

Get a single keypress via Hyperterminal.

Details
Returns ascii character corresponding to keypress with some preprocessing.
Escape sequences (Arrow keys and END) are mapped to decimal 240-244 (see defines)
Characters "0"-"9" converted to numbers 0-9
Lower case "a"-"z" converted to uppercase "A"-"Z"
Parameters
[in]nUartAddress- address of the UART peripheral in the memory map
Return values
Character,partiallydecoded.
