The Vinculum II IDE is used to create application code to run on VNC2. This section gives some example
source code, and explains its operation, used to drive the LCD display via the Vinco module.

4.1 VNC2 Initialisation
When generating firmware for VNC2, the first steps are to enable the Vinculum Operating System (VOS),
which controls the VNC2 services and device manager, defines the clock speed the core will use, and
defines the VNC2 pins that will be used. This is done in the function labelled main. The “main” function
for this application is shown as follows
Void main (void)
{
// GPIO context structure
// call VOS initialisation routines
The main function will also initialise the device drivers used in this application (GPIO in this case), it then
defines the threads that will be started (labelled firmware in this project) and finally it starts the VOS
scheduler. This is shown as follows:
// initialise device drivers
// TODO: call initialisation routines for included device drivers
Source code for the VNC2 writing to LCD Display
gpio_context_t gpioCtx;
vos_init(10, VOS_TICK_INTERVAL, NUMBER_OF_DEVICES);
vos_set_clock_frequency(VOS_48MHZ_CLOCK_FREQUENCY);
if
{
gpioCtx.port_identifier = GPIO_PORT_A;
gpio_init(VOS_DEV_GPIO,&gpioCtx);
// create threads for firmware application (no parameters)
tcbFirmware = vos_create_thread(29, SIZEOF_THREAD_MEMORY, firmware, 0);
// start VOS scheduler
vos_start_scheduler();
(vos_get_package_type() == VINCULUM_II_64_PIN)
// GPIO port A bit 0 to pin 51
vos_iomux_define_output(51,IOMUX_OUT_GPIO_PORT_A_0);
// GPIO port A bit 1 to pin 52
vos_iomux_define_output(52,IOMUX_OUT_GPIO_PORT_A_1);
// GPIO port A bit 2 to pin 55
vos_iomux_define_output(55,IOMUX_OUT_GPIO_PORT_A_2);
// GPIO port A bit 3 to pin 56
vos_iomux_define_output(56,IOMUX_OUT_GPIO_PORT_A_3);
// GPIO port A bit 4 to pin 57
vos_iomux_define_output(57,IOMUX_OUT_GPIO_PORT_A_4);
// GPIO port A bit 5 to pin 58
vos_iomux_define_output(58,IOMUX_OUT_GPIO_PORT_A_5);
// UART to V2EVAL board pins
