Hi guys,
new day, new problem, new question.
Im sending multiple Values over 2 XBEE modules. The values are coming from the USB HOST 2 library/USB Joystick. I can use the Datas when im using one Arduino. But now i though its more easier to handle the Datas when they are send over XBEE's.
Thats what i send via the library
Buf: 0817EB350010
In the code you can see where it comes from. They pity is: i dont know where the "BUF: 08...." is coming from....so i dont know the file and line. I thought i could easily take the code from the time when i only had the USB Joystick and the Arduino...but i didnt get it.
I tried to separate the Datas like it did before but i got all the time error messages.
Im reading in the second Arduino the Datas via WirelessData = Serial.read(). In the old example without XBEE's i had the "evt" marker and i could get the values out of the BUF value with the marker. My idea was to replace in the lines
virtual void Parse(HID *hid, bool is_rpt_id, uint8_t len, uint8_t *buf);
with
virtual void Parse(HID *hid, bool is_rpt_id, uint8_t len, uint8_t WirelessData);
unfortunately it wasnt that easy. Can anyone help me?
