当我试图运行simulink模型时,在编译和链接C/C++代码时遇到了以下错误

### Compiling "quantizer_sim_sfun.c"
我正在用ATtiny85和128x64pxOLED构建一个小玩具控制台。在我的初始构建中,我使用内置的shiftOut()和digitalWrite()函数将显示数据转移到屏幕控制器。
这使我感到有点失望。
我编写了自己的函数,使用直接端口操作来发送数据,并得到了速度大幅提高的23 bad,这是不错的。这是一个函数:
void shift_out_block(block)
{
byte b;
for (byte i = 0; i < 8; i++)
{
b = pgm_read_byte(block+i);
for (byte
我想做两次手术。首先,我想增加一个GameObject的大小,然后延迟0.1s,然后将它返回到原来的大小。然而,当我尝试使用StartCoroutine()时,它总是给出错误:
An object reference is required to access not-static members
即使我使延迟()函数保持静态。有人能告诉我我做错了什么吗?
public static void MoveSelected(int choice)
{
GameObject rock1 = GameObject.Find("Rock1");
GameObject pa
这是我的SQL

请回顾一下我执行的一份单链通知清单。
public class NodeS {
public int num;
public NodeS next;
public NodeS(int n){
this.num = n;
}
}

我有这样的乘客:
SELECT sc.no, scl.quantite, scl.description, scl.poids, scl.prix, sl_ref.refsl, sl_ref.codetva, sl_ref.tauxtva, sl_ref.compte
FROM shop_commande
AS sc, shop_commande_ligne AS scl, selectline_ref AS sl_ref
WHERE sc.id = scl.shop_commande_id
AND sl_ref.refshop = ISNULL(scl.shop_article_id
我有一段case语句,我希望执行该语句,但输出显示缺少关键字。请帮助我获得正确的输出。
CASE WHEN TRIM(STG.CLIENTCOUNTRY) in (select CPC_COUNTRY_CODE from ABC_DEVELOPER.EN_COUNTRY where COUNTRY_CODE='US')
THEN

这是我的代码,它应该能够渲染一个画布与蛇和它的食物,每当蛇在它的一个像素内,食物移动到一个新的位置。正如我在标题中所说的,错误为/;TypeError: pos is undefined
