Hi all,
I'm using libHid to do usb communication with Python to run in Linux and
Windows. The project has still a C++ code that communicates with the device
using HID.dll in Windows.
The complete code is in the final of this message:
For receive message:
in C++:
if (!(HidD_GetFeature)(g_hDevice, buf_ent, sizeof(buf_ent))) //Receive
message
g_hDevice is the deviceHandle, buf_ent is a pointer to the buffer
this I translated to Python as:
int, buffer = hid_get_feature_report(hid,path,64)
this good works..
but for send message
in C++:
if(!(HidD_SetFeature)(g_hDevice, &OUTPUT_BUFFER, sizeof(OUTPUT_BUFFER))
g_hDevice is the deviceHandle, OUTPUT_BUFFER is a pointer and the size of
the message.
in OUTPUT_BUFFER the first byte is the ReportID and always sets to zero (0).
and I tried to write this:
hid_set_feature_report(hid,path,'\0x2A\0x0C\0x00\0x00\0x43\0x05\0x0A\0x14\0x13\0x29\0x26\0x30\0xD7')
or hid_set_output_report.
"failed to send report to USB device 003/007[0]:error sending control
message: Connection timed out." But tells that the ReportID is 0x00.
the path I tried all that appears in debug mode, but You can view the
following complete code:
=======================================================================================
import sys
import time
from hid import *
def main():
hid_set_debug(HID_DEBUG_ALL)
hid_set_debug_stream(sys.stderr)
#hid_set_usb_debug(0)
ret = hid_init()
if ret != HID_RET_SUCCESS:
sys.stderr.write("hid_init failed with return code %d.\n" % ret)
hid = hid_new_HIDInterface()
matcher = HIDInterfaceMatcher()
matcher.vendor_id = 0x483
matcher.product_id = 0x0001
ret = hid_force_open(hid, 0, matcher, 3
)
if ret != HID_RET_SUCCESS:
sys.stderr.write("hid_force_open failed with return code %d.\n" % ret)
ret = hid_write_identification(sys.stdout, hid);
if ret != HID_RET_SUCCESS:
sys.stderr.write("hid_write_identification failed with return code
%d.\n" % ret)
ret = hid_dump_tree(sys.stdout, hid);
if ret != HID_RET_SUCCESS:
sys.stderr.write("hid_dump_tree failed with return code %d.\n" % ret)
ret = hid_close(hid)
if ret != HID_RET_SUCCESS:
sys.stderr.write("hid_close failed with return code %d.\n" % ret)
path = [0xffa000a5,0xffa000a9]
int, buffer = hid_get_feature_report(hid,path,64)
print buffer
time.sleep(2)
hid_set_feature_report(hid,path,'\0x2A\0x0C\0x00\0x00\0x43\0x05\0x0A\0x14\0x13\0x29\0x26\0x30\0xD7')
hid_cleanup()
hid_close(hid)
if __name__ == '__main__':
main()
