Vector提供了两种记录数据格式的格式规范：BLF和ASC。
先讲讲ASC。
参看：图文详解CAN Log文件 - ASC文件格式
一、ASC文件格式
在Vector提供的 CAN_LOG_TRIGGER_ASC_Format.pdf 提取码：ltjv 文件中，规定了CANoe/CANalyzer ASC记录中CAN、Log和Trigger event的格式。
1、Header
一个ASCII格式的日志文件以一个header开始。header包含关于日志文件的一般信息。
- base：表示记录的数值是hex十六进制或dec十进制的符号。
- timestamps：表示时间戳是absolute绝对写入测量的开始时间还是relative相对于前一个事件。
- internal：events logged表示是否记录了内部事件。
2、版本编号
从CANalyzer/CANoe v7.0开始，版本号以注释的形式写在Header之后：
- < major >.< minor >表示CANalyzer/CANoe的版本号
- < patch >表示CANalyzer/CANoe主版本中的修改版本（如服务包中的修改）。
3、经典CAN网络中的描述
二、C语言组包ASC文件
CAN2.0格式 ASC
double timeStamps = 0;
FILE* fp1 = fopen(FileName[filecnt], "a");
if (fp1 != NULL)
{
if (timeStamps == 0)
{
fprintf(fp1, "base hex timestamps absolute\n");
fprintf(fp1, "internal events logged\n");
fprintf(fp1, "// version 8.2.1\n");
}
timeStamps += 0.03;
const char* tail = " 244000 126 200000 7e04 51200550 4b140250";
//ASC
for (int i = 0; i < 3; i++)
{
fprintf(fp1, " %0.6f CANFD 1 Rx %x 0 0 8 8 %02x %02x %02x %02x %02x %02x %02x %02x %s\n", (timeStamps + i * 0.0001f), (0x750 + i * 3), \
SendBuffer[(i * 3)][0], SendBuffer[(i * 3)][1], SendBuffer[(i * 3)][2], SendBuffer[(i * 3)][3], SendBuffer[(i * 3)][4], SendBuffer[(i * 3)][5], SendBuffer[(i * 3)][6], SendBuffer[(i * 3)][7], tail);
timeStamps += 0.0002;
fprintf(fp1, " %0.6f CANFD 1 Rx %x 0 0 8 8 %02x %02x %02x %02x %02x %02x %02x %02x %s\n", (timeStamps + i * 0.0001f), (0x751 + i * 3), \
SendBuffer[(i * 3) + 1][0], SendBuffer[(i * 3) + 1][1], SendBuffer[(i * 3) + 1][2], SendBuffer[(i * 3) + 1][3], SendBuffer[(i * 3) + 1][4], SendBuffer[(i * 3) + 1][5], SendBuffer[(i * 3) + 1][6], SendBuffer[(i * 3) + 1][7], tail);
timeStamps += 0.0002;
fprintf(fp1, " %0.6f CANFD 1 Rx %x 0 0 8 8 %02x %02x %02x %02x %02x %02x %02x %02x %s\n", (timeStamps + i * 0.0001f), (0x752 + i * 3), \
SendBuffer[(i * 3) + 2][0], SendBuffer[(i * 3) + 2][1], SendBuffer[(i * 3) + 2][2], SendBuffer[(i * 3) + 2][3], SendBuffer[(i * 3) + 2][4], SendBuffer[(i * 3) + 2][5], SendBuffer[(i * 3) + 2][6], SendBuffer[(i * 3) + 2][7], tail);
timeStamps += 0.0002;
}
/* In order to be compatible with the final result and make a unified interface, the selection target is taken as the clustering result here, and the selection cluster is set to a fixed value */
fclose(fp1);
