  1. Hello, I'm trying to read the RF430-TMPSNS-EVM using Energia. I have the provided C code working with my MSP430FR4133 Reader. However, I want to send the temperature data over bluetooth using an HC05. I have bluetooth working in Energia code using serial. Now, how do I read the temperature? Can someone please help or point me in the right direction? Thanks, Kobe

    RFID Booster Pack for CC3200

    I put together a prototype Booster Pack that attaches to the CC3200 and has a RFID-RC522 card (sometimes called a MIFARE module), two buttons, and two LEDs. The CC3200 is connected to the cloud using Temboo. Currently it sends an email to me with information on the card used when accessed but it would be easy to modify to record time of access, card used, etc and put it into say a spreadsheet. This was a one afternoon plus an evening project for both hardware and software using Energia - very easy to do. The cards have security holes but I am pretty sure they pose too high a technical challenge for my local hooligans. I'm more afraid they might rip it apart and take my CC3200 than anything else. This is the Booster Pack, top view. Here it is attached to an upside down CC3200. In this photo it has been mounted in an enclosure and is reporting a successful read and transmission with the green LED. And if you are really interested, here is the schematic. I am using the RFID library located here. And if you aren't familiar with Temboo, find it here.
  3. Hi everybody, >>> UPDATE - Made "proper" Energia Library out of it. Now with proper named methods/class members<<< >>> UPDATE 2 - Added "keywords.txt" file for syntax highlighting, added comments to "Mfrc522.cpp" file explaining methods (thanks to Grant) - Added example to read cards contents of block 1 <<< >>> UPDATE 3 - You need to apply the USCI SPI fix proposed by Spirilis (post #22) in the following thread: http://forum.43oh.com/topic/3237-energia-library-nordic-nrf24l01-library/page-2 , otherwise the card reader won't work! <<<< I wanted to share my results with the MF RC522 RFID reader. I found an article from Grant Gibson (http://www.grantgibson.co.uk/blog/2012/04/how-to-get-started-with-the-mifare-mf522-an-and-arduino/#comments) where he used a cheap reader from eBay to read Mifare cards. (http://www.ebay.com/itm/Mifare-RC522-RFID-13-56Mhz-Module-SPI-Interface-with-a-IC-Card-/370690680474?pt=LH_DefaultDomain_0&hash=item564ee2e69a) The command set and technical aspects of the MFRC522 chip can be found in the datasheet: http://www.nxp.com/documents/data_sheet/MFRC522.pdf I have ported the example to Energia. Very simple by removing all Chinese comments and replacing uchar with unsigned chars. After these changes it works like a charm. Just connect the following lines: MOSI LP -> Pin 3 of the module MISO LP -> Pin 4 of the module PIn 1.3 LP -> Pin 1 of the module (SS) Pin 2.2 LP -> Pin 7 of the module (RST) Pin 1.5 LP -> Pin 2 of the module (SCK) GND LP -> Pin 6 of the module VCC LP -> Pin 8 of the module Pin 5 is not connected. Included is the sketch (Mfrc522.zip) I used. Now onto opening doors and paying electronically! Kind regards, Eelco
  4. Hi, I would like introduce my last boosterpack - 43Oh_RFID. I use very popular chip -> NFRC522 (energia library was posted at: http://forum.43oh.com/topic/4028-energia-library-nfc-card-reading-with-energia-mf-rc-522/). Schematic diagram Element placement: PCB files (zipped traxmaker/protel 2.0) 43Oh_RFID.zip and mounted boosterpack

    MSP430 as a RFID Reader processor

    Hi everybody, I`m already designed RF front-end to capture RFID data. now I can recieve Tag signal in miller4 and in 256khz frquency. anybody here can help me in: 1: how can I capture this data and do decoding of the signal in a MSP430? 2: what is minimum system frequency is required to capture recieved signal without missing any data? 3: anybody here did the Miller4 decoding in C or C++? 4: should I store the signal first and then process the data? or I can detect each bit on interrupt routin? any information or help or sample code is so appereciated. also if anybody coded a UHF RFID reader and decoding and protocols for MSP430 before, help me please.
  6. Hi All, I am trying to study again on a Mifare reader, that i used to play with using this library on Arduino: https://github.com/marcboon/RFIDuino/tree/master/SL018">https://github.com/marcboon/RFIDuino/tree/master/SL018 When a tag is sensed, the demo program from the link above is displaying information like this: ### CMD_LOGIN - read@@Block 0C: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................@@Block 0D: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................@@Block 0E: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................@@Block 0F: 00 00 00 00 00 00 FF 07 80 69 FF FF FF FF FF FF .........i...... I used to believe the data are actually from the tag, but as i read more about the standard from the Internet, I became aware that Mifare provides sector encryption. So, I'm not sure the demo code will still give some data (garbage, zeros, or something else) on sectors that are encrypted, or the code will display error message instead. If anyone have used this library and can kindly teach me on this? I have studied the demo code and found that it is using a read login code that passes a "transport key" of 0xFF as in the void SL018::authenticate(byte sector) method : void SL018::authenticate(byte sector){ data[0] = 9; data[1] = CMD_LOGIN; data[2] = sector; data[3] = 0xAA; memset(data + 4, 0xFF, 6); transmitData(); } There is another method that accept a "decryption key" but it is not used in the demo code: void SL018::authenticate(byte sector, byte keyType, byte key[6]){ data[0] = 9; data[1] = CMD_LOGIN; data[2] = sector; data[3] = keyType; memcpy(data + 4, key, 6); transmitData(); } The demo code called the authenticate method with the standard "FF" (only one argument, the sector) on every write: ...else{ authenticated = false; rfid.authenticate(block >> 2); } Any hints will be much appreciated. Thanks in advance.
