(((void ()(void))((unsigned long )0x2c)))(); 是什么意思？
在8962的boot_demo1中 (((void ()(void))(*(unsigned long *)0x2c)))(); 是什么意思？是把程序引导到地址为0X2C的位置？

这个语句会执行位于bootloader的SVC(软中断)异常服务例程,还是分解一下吧：

(*(unsigned long *)0x2c)：将0x2C强制转化为unsigned long类型指针，并指向该地址所在的数据；

void (*)(void) ：函数指针，指针名为空，该函数参数为空，返回值为空

(void ()(void))((unsigned long *)0x2c)：将Flash地址0x2C中的内容强制转化为函数指针，该函数参数为空，返回值为空

(((void ()(void))(*(unsigned long *)0x2c)))()；：调用函数，即开始从启动代码中的UpdateHandler标号处开始执行

  客户端请求动态定义数据标识符，这些数据标识符随后可以由 0x22(ReadDataByIdentifier) 服务读取。该服务的目的是为客户端提供将一个或多个数据元素分组为数据超集的功能，可以通过 0x22(ReadDataByIdentifier) 或0x2A(ReadDataByPeriodicIdentifier) 服务进行整体请求。动态定义的 dataIdentifier 会将包含数据参数定义的串联。分组的数据元素可以由以下任何一个组成： —— 源数据标识符，位置和大小 —— 内存地址和内存长度

0x2C动态定义数据标识符服务
qiu421的博客
09-29 371
其实就是临时在指定地址创建个信息DID，里面可以存写临时数据，到时候可以给自己读写，但是这东西一重启或者过段时间就没了。要用0x22服务去读取，0x2A来写，不能用0x2E来写，协议认为0x2E不能指定地址来写。这个服务将会有内存溢出的风险，就需要程序去做限制和把控了，规定好那块区域可以用来作为临时存储的，一旦超过剩余可使用空间就不能够动态定义数据了。动态定义出来的数据标识符和空间，也可以动态删除。有两种参数选配：1、源数据标识符、位置、大小。
void* 地址应该使用long long 类型 进行转换
努力学习中的博客

void* 地址如果要强制转换需要使用long long 类型 进行转换 否则如果地址值很大，使用long，int类型转换会出错
理解(*(void(*)())0)();

先说一下强制转换，可以跳过。例子: #include #include int main() {     uint16_t a = 0xA5A1;     uint8_t   b;     b = (uint8_t)a;    // 16位强制转换为8位     printf("b=0x%X",b);  } a是16位，b是8位，将a进行一次强制转换的结果给b。 我这里的输出结果是 b=0x

((void(code *)(void))0x0000)()的理解
03-19 2305
首先去括号得到(void(code *)(void))0x0000，这句话很明显是把0x0000强制类型转换成某个东西。 然后再去括号得到void(code *)(void)，这句话的意思是一个函数指针类型，无参数，无返回值。 整体的意思是把0x0000当做一个无参数无返回值的函数指针，再对这个函数进行调用。 其作用就是调用0x0000位置处存放的某个函数代码 ...
