SBUS2 Disable and Enable

[ericlangel]

on a local Project i had the Issue with random System Crash when writing to the Internal Flash (FFAT/SPIFFS).

SBUS2 disable() and Enable() funtions were made for this to switch off SBUS2 Interrupts during Flash write.

But on my local project it did not work.

void SBUS_disable(){
  uart_disable_rx_intr(UART_NUM_2);
  timer_set_alarm(TIMER_GROUP_0,TIMER_1,TIMER_ALARM_DIS);
}

should be changed to

void SBUS_disable() {
  timer_disable_intr(TIMER_GROUP_0, TIMER_1);
  uart_disable_rx_intr(UART_NUM_2);
}

void SBUS_enable() {
  uart_enable_rx_intr(UART_NUM_2);
  timer_enable_intr(TIMER_GROUP_0, TIMER_1);
  initialize_slot_status();
  enable_receiving();
}
