  1. Hi all, I am working on reading NFC tags using MSP EXP430G2ET Rev 1.0 launchpad with the MSP430G2553 microprocessor and DLP 79070ABP booster pack. I have used the attached header files and wrote the attached code on Energia v1.8.7E21 on Windows 10. I have all the drivers installed for the above Launchpad and also tried uploading the sketch for blinking LED and analog sensor serial reading which are working as expected. But when I try to upload the code for reading the NFC Tags, it showing the following error log: D:\pmk\NUSProject\energia-1.8.7E21-windows\energia-1.8.7E21\hardware\energia\msp430\cores\msp430\atof.c: In function 'atof': D:\pmk\NUSProject\energia-1.8.7E21-windows\energia-1.8.7E21\hardware\energia\msp430\cores\msp430\atof.c:71:9: warning: floating constant exceeds range of 'double' [-Woverflow] libraries\TRF7970ABP\trf7970BoosterPackEnergia.cpp.o:(.bss.stand_alone_flag+0x0): multiple definition of `stand_alone_flag' sketch\trf7970BoosterPackEnergia.cpp.o:(.bss.stand_alone_flag+0x0): first defined here d:/pmk/nusproject/energia-1.8.7e21-windows/energia-1.8.7e21/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/TRF7970ABPDemo.ino.elf section `.text' will not fit in region `rom' d:/pmk/nusproject/energia-1.8.7e21-windows/energia-1.8.7e21/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: section .vectors loaded at [0000ffe0,0000ffff] overlaps section .text loaded at [0000c000,00010677] d:/pmk/nusproject/energia-1.8.7e21-windows/energia-1.8.7e21/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: region `rom' overflowed by 2734 bytes d:/pmk/nusproject/energia-1.8.7e21-windows/energia-1.8.7e21/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3\libcrt0.a(_copy_data.o): In function `__do_copy_data': /root/mspgcc-20120406/BUILD/gcc/gcc/../../../gcc-4.6.3/gcc/config/msp430/crt0.S:195: relocation truncated to fit: R_MSP430_16_BYTE against symbol `__data_load_start' defined in *ABS* section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/TRF7970ABPDemo.ino.elf C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(main.cpp.o): In function `main': main.cpp:(.init9+0x2): relocation truncated to fit: R_MSP430_16 against symbol `init' defined in .text.init section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring.c.o) libraries\TRF7970ABP\utility\trf7970.cpp.o: In function `trf7970::trf7970(unsigned char, unsigned char, unsigned char, unsigned char, unsigned char, unsigned char)': trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x18): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x20): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x2a): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x32): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x3a): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x42): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x52): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x5c): relocation truncated to fit: R_MSP430_16 against symbol `pinMode' defined in .text.pinMode section in C:\Users\PMK\AppData\Local\Temp\arduino_build_374378/core\core.a(wiring_digital.c.o) trf7970.cpp:(.text._ZN7trf7970C2Ehhhhhh+0x66): additional relocation overflows omitted from the output collect2: ld returned 1 exit status exit status 1 Error compiling for board MSP-EXP430G2ET w/ MSP430G2553.

  2. I recent completed the prototype of my LoginNFC project. It's a combination of MSP430 acting as a USB keyboard (and CDC serial for configuration) and a TRF7970A NFC reader. The prototype was done with a F5529 LaunchPad and TRF7970A Booster - along with a ferrite antenna to improve the read range. It's working well and I did a small write-up here: https://0xfred.wordpress.com/2015/01/14/nfc-login-version-1-0/ However, I don't really feel it's complete until I've got it off the dev board and made a decent PCB. This is my first double-sided PCB, first time with USB, first time with LQFP and QFN. Before I print out the transparencies and start etching (yes - I'm planning to hom eetch this) I thought I'd throw it out there for criticism - constructive or otherwise. Lots of inspiration from @@RobG and his F5510 board along with TI's reference designs.Thanks for that. I'm sure I've have messed up somewhere though! Here's what I've got. The vias are large (and the drill small) because they will be done with 0.6mm copper rivets. I thought I'd give myself a bit of leeway for centering the hole when I drill them. I've tried to minimise them and they'll be done by hand but there still seems to be more than I'd like. The part that's off the board is an inductor that seems to work well as an antenna. I need to get my implant as close as possible beside it. Eagle files attached if anyone wants to take a closer look. LoginNFC.sch LoginNFC.brd
  3. The TRF7970A NFC booster back (made by DLP Design) is now available direct from TI. It's also available as a bundle with a G2 or F5529 Launchpad but costs the same as buying these seperately. http://www.ti.com/tool/DLP-7970abp Perfect timing for me in the UK as I was going to be stung with
  4. hi,frnds i would like to work with cc3200 and nfcboosterpack trf7970a in energia IDE .Does any one have energia library for TRF7970A boosterpack. i have attached a pdf which helps to make a library for iso1443a and iso5693 i tried this code for msp430g2553 but its not working please any one can help me TestTRF7970A_with_BPV3 (1).pdf nfcpin.pdf #include<SPI.h> #define enable P2_2 #define CS P2_1 #define interrupt P2_0 #define CS_ENABLED digitalWrite(CS,LOW) #define CS_DISABLED digitalWrite(CS,HIGH) void setup() { // put your setup code here, to run once: pinMode(CS,OUTPUT); pinMode(enable,OUTPUT); digitalWrite(enable,LOW); pinMode(interrupt,INPUT); SPI.setDataMode(SPI_MODE1); SPI.setClockDivider(SPI_CLOCK_DIV8); SPI.setBitOrder(MSBFIRST); SPI.begin(); Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: let(); } void let(void) { CS_ENABLED; Write(0x83); CS_DISABLED; CS_ENABLED; Write(0x09); Write(0x31); CS_DISABLED; CS_ENABLED; Read(0x49); CS_DISABLED; CS_ENABLED; Write(0x01); Write(0x88); CS_DISABLED; CS_ENABLED; Read(0x41); CS_DISABLED; CS_ENABLED; Write(0x00); Write(0x20); CS_DISABLED; CS_ENABLED; Read(0x40); CS_DISABLED; CS_ENABLED; Write(0x01); Write(0x88); CS_DISABLED; CS_ENABLED; Write(0x8F); Write(0x90); Write(0x3D); Write(0x00); Write(0x0F); Write(0x26); CS_DISABLED; delay(100); CS_ENABLED; Write(0x6C); Read(0xC0); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x5C); Read(0x02); CS_DISABLED; CS_ENABLED; Write(0x7F); Read(0x04); Read(0x00); CS_DISABLED; CS_ENABLED; Write(0x8F); CS_DISABLED; CS_ENABLED; SPI.transfer(0x4F); Read(0x7F); CS_DISABLED; delay(20); CS_ENABLED; Write(0x8F); Write(0x90); Write(0x3D); Write(0x00); Write(0x20); Write(0x93); Write(0x20); CS_DISABLED; delay(5); CS_ENABLED; Write(0x6C); Read(0xC0); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x5C); Read(0x05); CS_DISABLED; CS_ENABLED; Write(0x7F); Read(0xCD); Read(0x88); Read(0x77); Read(0x66); Read(0x00); delay(10); CS_DISABLED; CS_ENABLED; Write(0x6C); Read(0x00); Read(0x3E); CS_DISABLED; CS_ENABLED; Write(0x8F); CS_DISABLED; CS_ENABLED; Write(0x4F); Read(0x7F); CS_DISABLED; } void Read(byte data ) { Serial.print(SPI.transfer(data)); } void Write(byte data) { SPI.transfer( data); }
  5. Hi All, I'm looking at this booster pack which is now available from TI estore. http://www.ti.com/tool/dlp-7970abp Appreciate any advice from the forum. Not have a specific project goal, but since I don't own anything NFC and also apparently this boosterpack can read Felica card (a major transportation card standard where I live), this looks pretty appealing. My wife's phone is NFC capable so some experiments with it is also cool (short experiments only, of course ) Specific questions: 1. From the documentation, the NFC Link software seems to be using serial to communicate. Are the commands / response available publicly so that the firmware can be utilized without the NFC link software? 2. What kind of card is included? Is it kind of "soft" tag, or a hard card? Thanks in advance.
