```python
from TSMasterAPI import *

# Specify BLF file path (requires absolute path)
blf_path = "E:\\logs\\can_log.blf".encode("utf8")

# Start logging
result = tsapp_start_logging(blf_path)
if result == 0:
    print("Start logging messages")
else:
    print(f"Logging failed to start, error code: {result}")

# ... run for a period to collect messages ...

# Stop logging
tsapp_stop_logging()

# Prepare response buffer
response_data = (c_uint8 * 1000)()
response_size = c_int(1000)

# Send request and get response
result = tstp_can_request_and_get_response(
    uds_handle,     # Diagnostic module handle

```python
from TSMasterAPI import *
from ctypes import c_int32

# Create BLF file
write_handle = c_int32(0)
output_path = "E:\\logs\\output.blf".encode("utf8")

result = tslog_blf_write_start(output_path, write_handle)
if result == 0:

使用网络、节点、报文和信号名称定位并操作信号值。需要使用 ctypes 库处理数据类型。

```python
from TSMasterAPI import *
from ctypes import c_double

# 设置信号值
result = tscom_can_rbs_set_signal_value_by_element(
    0,                                  # 通道索引
    "CAN_FD_Powertrain".encode("utf8"), # 网络名称
    "Engine".encode("utf8"),            # 节点名称
    "GearBoxInfo".encode("utf8"),       # 报文名称
    "Gear".encode("utf8"),              # 信号名称
    c_double(3.0)                       # 信号值
)

if result == 0:
    print("信号值设置成功")

# 读取信号值
signal_value = c_double(0)
result = tscom_can_rbs_get_signal_value_by_element(
    0,                                  # 通道索引
    "CAN_FD_Powertrain".encode("utf8"), # 网络名称
    "Engine".encode("utf8"),            # 节点名称
    "GearBoxInfo".encode("utf8"),       # 报文名称
    "Gear".encode("utf8"),              # 信号名称
    signal_value                        # 接收信号值
)

if result == 0:
    print(f"当前信号值: {signal_value.value}")
```

### Load and Unload CAN DBC Database Files

Source: https://context7.com/sy950915/tsmasterapi/llms.txt

Loads CAN DBC database files using tsdb_load_can_db, specifying the file path, associated channels, and receiving a database handle. Unloads all loaded DBC files with tsdb_unload_can_dbs.

```python
from TSMasterAPI import *
from ctypes import c_int32

# 加载 DBC 文件
db_handle = c_int32(0)
dbc_path = "C:/path/to/database.dbc".encode("utf8")

### Receive CAN/CANFD Messages via FIFO

Source: https://context7.com/sy950915/tsmasterapi/llms.txt

Enables FIFO reception with tsfifo_enable_receive_fifo and reads messages using tsfifo_receive_can_msgs and tsfifo_receive_canfd_msgs. Allows specifying channel and read type (receive/transmit/both).

```python
from TSMasterAPI import *
from ctypes import c_int32

# 启用 FIFO 接收
tsfifo_enable_receive_fifo()

# 准备接收缓冲区
can_buffer = (TLIBCAN * 100)()      # 100 条 CAN 报文缓冲
canfd_buffer = (TLIBCANFD * 100)()  # 100 条 CANFD 报文缓冲
can_count = c_int32(100)
canfd_count = c_int32(100)

# 接收报文（通道0，收发报文都读取）
result_can = tsfifo_receive_can_msgs(can_buffer, can_count, 0, READ_TX_RX_DEF.TX_RX_MESSAGES)
result_canfd = tsfifo_receive_canfd_msgs(canfd_buffer, canfd_count, 0, READ_TX_RX_DEF.TX_RX_MESSAGES)

# 处理接收到的 CAN 报文
print(f"接收到 {can_count.value} 条 CAN 报文")
for i in range(can_count.value):
    msg = can_buffer[i]
    print(f"ID: 0x{msg.FIdentifier:X}, DLC: {msg.FDLC}, Data: {[hex(msg.FData[j]) for j in range(msg.FDLC)]}")

# 处理接收到的 CANFD 报文
print(f"接收到 {canfd_count.value} 条 CANFD 报文")
for i in range(canfd_count.value):
    msg = canfd_buffer[i]
    print(f"ID: 0x{msg.FIdentifier:X}, DLC: {msg.FDLC}")
```

### Set Up Cyclic Transmission for CAN/CANFD Messages

Source: https://context7.com/sy950915/tsmasterapi/llms.txt

Configures periodic automatic transmission of CAN and CANFD messages using tsapp_add_cyclic_msg_can and tsapp_add_cyclic_msg_canfd. Use tsapp_delete_cyclic_msg_can and tsapp_delete_cyclic_msg_canfd to stop these tasks.

```python
from TSMasterAPI import *

# 创建报文
msg = TLIBCAN(FIdentifier=0x100, FData=[0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08])
fdmsg = TLIBCANFD(FIdentifier=0x200, FFDProperties=1, FData=[0x10, 0x11, 0x12, 0x13])

# 添加周期发送任务，周期100毫秒
ret1 = tsapp_add_cyclic_msg_can(msg, 100)
ret2 = tsapp_add_cyclic_msg_canfd(fdmsg, 100)

if ret1 == 0 and ret2 == 0:
    print("周期发送任务添加成功")

# ... 运行一段时间后停止周期发送 ...

# 删除周期发送任务
tsapp_delete_cyclic_msg_can(msg)
tsapp_delete_cyclic_msg_canfd(fdmsg)
print("周期发送任务已停止")
```

# Open BLF file
blf_id = c_int32(0)
msg_count = c_ulong(0)
blf_path = "E:\\logs\\can_log.blf"

result = tslog_blf_read_start(blf_path, blf_id, msg_count)
if result == 0:
    print(f"BLF file opened successfully, {msg_count.value} messages in total")

    # Read messages
    real_count = c_ulong(0)
    msg_type = TSupportedObjType.sotUnknown
    can_msg = TLIBCAN()
    canfd_msg = TLIBCANFD()
    lin_msg = TLIBLIN()

    for i in range(msg_count.value):
        tslog_blf_read_object(blf_id, real_count, msg_type, can_msg, lin_msg, canfd_msg)

        if msg_type.value == TSupportedObjType.sotCAN.value:
            print(f"CAN: Time={can_msg.FTimeUs/1000000:.6f}s, "
                  f"ID=0x{can_msg.FIdentifier:X}, DLC={can_msg.FDLC}")
        elif msg_type.value == TSupportedObjType.sotCANFD.value:

        # 修改报文数据
        acan.contents.FData[0] += 1
        print(f"处理报文 ID=0x{acan.contents.FIdentifier:X}")

# 创建回调函数包装器
on_can_callback = TCANQueueEvent_Win32(on_can_event)
obj = c_int32(0)
