Hi
I have the following problem with above mentioned function:
Every time i command the CR95HF to get in the Tag Detection Mode it wakes up immediately. I get the following response from CR95HF:
00 01 02�?�?
The Command i give the CR95HF is the following:
char DataOut[16] = {0x07, 0x0E, 0x02, 0x21, 0x00, 0x79, 0x01,
0x18, 0x00, 0x20, 0x60, 0x60, 0x64, 0x74,
0x3F, 0x08};
//Byte structure Byte content
(0x07); //Command Idle
(0x0E); //Length
(0x02); //WU Source + LFO frequency Source = Tag Detection
(0x21); //EnterCtrlL Tag Detection
(0x00); //EnterCtrlH Tag Detection
(0x79); //WUCtrlL Tag Detection
(0x01); //WUCtrlH Tag Detection
(0x18); //LeaveCtrlL Tag Detection / can´t differ from 0x1800
(0x00); //LeaveCtrlH Tag Detection / can´t differ from 0x1800
(0x20); //WU Period Time allowed between two Tag Detections
(0x60); //Osc Start Defines delay for HFO stabilization
(0x60); //DacStart Defines delay for DAC stabilization
(0x64); //DacDataL Define lower and higher DAC comparator values
(0x74); //DacDataH
(0x3F); //SwingsCnt Numer of HF swings allowed during Tag Detection
(0x08); //MaxSleep Maximum number of tag detection trials�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
I cant estimate where things go wrong, the Wake Up by low Pulse on IRQ IN works fine and, of course, there is no NFC Tag close to the CR95HF´s Antenna.
