NXP-NCI LPC122x example

breezeto — Tue, 18 Oct 2016 05:11:04 GMT

Hello,

I'm testing the NXP-NCI LPC122x example on OM5578/PN7150 NFC Controller demo kit + OM13008: LPCXpresso™ Board for LPC1227

The I2C communication is working between PN7150 and LPC1227.

The program loop to call the tml_WaitForRx function and check the IRQ pin.

But the IRQ pin has not been changed even place the NXP's NFC sample card on the antenna.

Do I need to make some change on the code for PN7150?

Thanks for your valuable comments and suggestions~

Hello~

Anyone know how can I get a support from NXP?

I just want to execute the NXP's Example on OM5578/PN7150 NFC Controller demo kit + OM13008: LPCXpresso™ Board for LPC1227 properly~

Thanks so much~

NXP won't provide any support on their demo kit and development platform????

I just want to make your example code and your demo kit working together~~~~

Does not NXP support know how to solve this problem?

I have been waiting for almost a month and just want to execute NXP Example code!!!!

There seems to be a problem starting the discovery loop on PN7150. Discovery loop is used to poll for cards and is started with the

NCI >> 21 03 15 0a ....

command.

NCI << 41 03 01 00

is the acknowledge but the next line says that there is something wrong with starting the dicovery loop:

NCI << 60 00 06 a0 00 79 df 00 00

60 00 means NCI CORE RESET notification, so PN7150 performs a reset. '79 df 00 00' is the debug information or in fact the indication why the reset happen.

Reset in such situation can have two issues:

- The transmitter LDO can't be started because supply for LDO is not there

- The XTAL oscillator and/or the PLL for generating the 13.56Mhz RF frequency can't be started

Assuming you use the OM5578 demoboard - are you supplying the VANT pin (5V)?

Christian.

Dear Christian,

Thank you for your valuable comments.

I have checked the voltage of VANT pin which is DC 5V and this pin is connected to the +5VIN on LPCXpresso™ Board for LPC1227. After checked the Board Schematics from LPC1227 LPCXpresso Board | Embedded Artists AB

It found that this pin is not a 5V power supply (even it can measure a DC 5V).

I made a mistake on that.

Finally, I tried to connect the VANT pin to an external 5V power supply and all thing are working.

I would like to know the detail about the acknowledge data from NCI.

Would you give me an idea what document will show that?

Thanks again~
