Hallo
Currently, I am evaluating the SE050 with S32K148 board using I2C connection. SE050 only connected as slave mode with S32K148 board and did not connect any sensors with SE050.
1. I did software reset (Got info from old posts)
2.
uint8_t versionPacket[] = { 0x5A, // NAD
0x20, // PCB
0x05, // LEN
0x80, // CLA
0x04, // INS
0x00, // P1
0x20, // P2
//0x00, // Lc
0x09, // Le
0x66, // CRC1
0xAA //CRC2
};
Sent the above data and got response (I am new to this topic Do not know How to calculate CRC1 and CRC2)
Output
-----
0xa5, 0x90 , 0x00, 0xfb, 0xe9
Now I am bit confusing regarding the applet selection to get the version.
uint8_t versionPacket1[] = { 0x5A, // NAD
0x20, // PCB
0x05, // LEN
0x00, // CLA
0xA4, // INS
0x04, // P1
0x00, // P2
0x10, // Lc
0x00, // Le
//0x66, // CRC1
//0xAA //CRC2
};
Is this correct packet??
Do I need to add also the payload (Payload 0xA0000003965453000000010300000000)??
Whats are the steps for evaluating the Se050 chip??
Thanks in advance,
Sai
Hi @saireddy_saredd ,
I think you may evaluate SE050 with FRDM-K64 at first then try to port the code for K64F to S32K148. Please kindly refer to https://www.nxp.com.cn/docs/en/application-note/AN12448.pdf for more details.
Hope that helps,
Have a great day,
Kan
