1. I use a special board
2. I output debugging information through the interfaces of the microcontroller that controls the CR
3. I'll check the messages the command returns. Thank you. I'll write about it
4. I measure the current on resistor in line power supply. The current consumption of the CR95HF (in the RF mode) differs. It's about 40mA. In addition, I see on the oscilloscope RF on the antenna.
In my project I need to always sleep, wake up once every 5 minutes, read one block from the tag and fall sleep again. Here is my simplified code:
int main( void ) {
...
SET_INTR();
SET_SSI_0(); // Set SPI Interface
CLR_SSI_1();
Delay_mSeconds(200);
CR95HF_Reset();
SetProtocol_Command() ;
Info_Command();
while (1) {
for (INT08U i=0; i<2;i++) {
if (Inventory_Command()) {
ReadCurrend();
break;
}
}
Hibernate_Command();
Delay_mSeconds(5000); // In a real project, the controller goes into low power mode
CLR_INTR();
Delay_mSeconds(4); // < 4ms not working..
SET_INTR();
SetProtocol_Command() ;
Delay_mSeconds(30);
}
...
}
