Второе редактирование: теперь мне каким-то образом удалось запустить скрипт (изменив int main (void) на int main ()) с определенным «for», однако он вопиюще игнорирует меня и работает бесконечно в любом случае:
int main() { // was int main(void)!!
// We'll start by performing hardware and peripheral setup.
SetupHardware();
// We'll then enable global interrupts for our use.
GlobalInterruptEnable();
//int counter = 0;
//int x_times = 1000;
// Once that's done, we'll enter an infinite loop.
for (day = 0;day = 2;day++) // RE-ENABLE THIS TO PUT THE INFINITE LOOP BACK IN!
// trying to make a loop that will only run a certain number of times (5)...
{
// We need to run our task to process and deliver data for our IN and OUT endpoints.
HID_Task();
// We also need to run the main USB management task.
USB_USBTask();
}
return 0;
}
Редактировать 1: с некоторыми уточнениями:
Этот код взят из проекта, чтобы Arduino выглядел как джойстик для Nintendo Switch, основанный на https://github.com/shinyquagsire23/Switch-Fightstick .
Я думаю, что Arduino использует микропрограмму, отличную от той, которая поставляется с ним, так как весь скрипт высвечивается на Arduino после того, как 'make' компилирует файл .hex, включая Joystick. c и другие скрипты также. Я включу весь контент Joystick. c ниже с комментариями от первоначального разработчика в надежде внести ясность в этот запрос.
/*
Nintendo Switch Fightstick - Proof-of-Concept
Based on the LUFA library's Low-Level Joystick Demo
(C) Dean Camera
Based on the HORI's Pokken Tournament Pro Pad design
(C) HORI
This project implements a modified version of HORI's Pokken Tournament Pro Pad
USB descriptors to allow for the creation of custom controllers for the
Nintendo Switch. This also works to a limited degree on the PS3.
Since System Update v3.0.0, the Nintendo Switch recognizes the Pokken
Tournament Pro Pad as a Pro Controller. Physical design limitations prevent
the Pokken Controller from functioning at the same level as the Pro
Controller. However, by default most of the descriptors are there, with the
exception of Home and Capture. Descriptor modification allows us to unlock
these buttons for our use.

Привет всем, впервые публикуя сообщения и в основном новичка на C ++ - пожалуйста, помилуйте!
Мне кажется, у меня необычная проблема: у меня есть сценарий C ++ для Arduino, который повторяется бесконечно. Я хотел бы, чтобы этот скрипт выполнялся только определенное количество раз, но все, что я пробовал до сих пор, терпит неудачу.
Это оригинальный фрагмент скрипта с бесконечным l oop:
int main(void) {
SetupHardware();
GlobalInterruptEnable();
for (;;)
{
HID_Task();
USB_USBTask();
}
}
И это то, что я пытался сделать, чтобы скрипт запускался всего два раза:
int main(void) {
SetupHardware();
GlobalInterruptEnable();
int day = 0;
for (day = 0; day <= 2; day++)
{
HID_Task();
USB_USBTask();
}
return;
}
Я пытался избавиться от «возврата», и в соответствии с «make» код выглядит нормально, так как я не получаю никакого сообщения об ошибке. Однако, когда я запускаю sh Arduino с этим скриптом, он не работает вообще. В тот момент, когда я восстанавливаю бесконечное l oop, все возвращается к нормальной работе (и бесконечно).
Для справки, вот ссылка на проект GitHub, файл, который я пытаюсь отредактировать, - это джойстик. c: https://github.com/bertrandom/snowball-thrower
Я немного потерян и все уши / глаза для совета.
Спасибо!
