Part Number: MSPM0G5187
The tinyusb example on this MCU uses systick as a millis counter.
volatile uint32_t system_ticks = 0u;
void SysTick_Handler(void)
{
system_ticks++;
}
uint32_t board_millis(void) {
return system_ticks;
}
Is it safe to access system_ticks this way? I usually turn turn off systick interrupts like this:
uint32_t board_millis(void) {
uint32_t dummy;
NVIC_DisenableIRQ(SysTick);
dummy = system_ticks
NVIC_EnableIRQ(SysTick);
return dummy;
}
Or am I being too paranoid?
Can I also not worry about disabling interrupts with the MSPM33C321?
