  1. Hi, Months ago I ordered this booster pack ( 2.2 240x320 LCD V2 )and so far I haven't used it. I would like to know if it is CC3200 compatible. I Dont want to plug it on cc3200 board, just wire it but I do not understand this BP pinout. Can someone help me Thanks and salutations.
  2. Hi, May be this help : http://playground.arduino.cc/Code/TimingRollover Salutations
  3. Hi, Ethernet example " EthernetWebServer " doesn't compile under Energia 013 here is error message : In file included from awebserver.ino:8:0: C:\Users\Nardo\energia-0101E0013\hardware\lm4f\libraries\Ethernet/Ethernet.h:12:28: error: redefinition of 'const IPAddress INADDR_NONE' In file included from C:\Users\Nardo\energia-0101E0013\hardware\lm4f\libraries\Ethernet/Ethernet.h:8:0, from awebserver.ino:8: C:\Users\Nardo\energia-0101E0013\hardware\lm4f\cores\lm4f/IPAddress.h:73:17: error: 'const IPAddress INADDR_NONE' previously declared here Under Energia012 it compiles and runs ok. Thank you and Salutations Bernard.
  4. I think it's true, although I added a 10uF cap, sometimes the program freeze when server get a client and need more power. I will try a 47uF. To be continued ... Salutations
  5. Hi, Finaly everything is ok .. a 10uF on the nRF24l01 breakout !!! Sorry for the inconvenience caused. Best regards Bernard
  6. @spirillis : thanks for replying. Yes Internet part works when I comment out Enrf24-related items. When I comment out //Ethernet.begin(mac, ip); //server.begin(); radio is ok and I get DHT22 values. Another clue, Resetting the TM4C129 board several times .. sometimes I cans see DHT22 values : copy of terminal with loop debug : Enrf24 radio transceiver status: DEEP SLEEP <1uA power consumption Loop begin <---- nada Enrf24 radio transceiver status: DEEP SLEEP <1uA power consumption Loop begin <---- nada Enrf24 radio transceiver status: DEEP SLEEP <1uA power consumption Loop begin 41.5---25.2 <----- good values miracle !!! if End Loop Loop begin salutations

  14. Hello, I am trying to use rotary library for my VFO ad9850. Originally writen for Arduino I just changed PCINT for PORT2_VECTOR interrupt. so far can say it almost works but I get some issues I cannot understand Here is my test code : /* encoder_test.ino Energia 011 MSP430G2553 launchpad ver 1.5 Windows 7 Rotary encoder KY-040 */ #include <msp430g2553.h> #include "rotary.h" Rotary r = Rotary(P2_1, P2_2); void setup() { Serial.begin(9600); P2DIR &= ~(BIT1 + BIT2); P2IES = BIT1 + BIT2 ; //high to low transition P2OUT |= BIT1 + BIT2; P2REN = BIT1 + BIT2; P2IE = BIT1 + BIT2; P2IFG &= ~BIT1 + BIT2; _BIS_SR(GIE); } void loop() { } #pragma vector=PORT2_VECTOR __interrupt void port_2 (void) { unsigned char result = r.process(); if (result) { Serial.println(result == DIR_CW ?

Licenced under the GNU GPL Version 3. * Contact: bb@cactii.net * * A typical mechanical rotary encoder emits a two bit gray code * on 3 output pins. Every step in the output (often accompanied * by a physical 'click') generates a specific sequence of output * codes on the pins. * * There are 3 pins used for the rotary encoding - one common and * two 'bit' pins. * * The following is the typical sequence of code on the output when * moving from one step to the next: * * Position Bit1 Bit2 * ---------------------- * Step1 0 0 * 1/4 1 0 * 1/2 1 1 * 3/4 0 1 * Step2 0 0 * * From this table, we can see that when moving from one 'click' to * the next, there are 4 changes in the output code. * * - From an initial 0 - 0, Bit1 goes high, Bit0 stays low. * - Then both bits are high, halfway through the step. * - Then Bit1 goes low, but Bit2 stays high. * - Finally at the end of the step, both bits return to 0. * * Detecting the direction is easy - the table simply goes in the other * direction (read up instead of down). * * To decode this, we use a simple state machine. Every time the output * code changes, it follows state, until finally a full steps worth of * code is received (in the correct order). At the final 0-0, it returns * a value indicating a step in one direction or the other. * * It's also possible to use 'half-step' mode. This just emits an event * at both the 0-0 and 1-1 positions. This might be useful for some * encoders where you want to detect all positions. * * If an invalid state happens (for example we go from '0-1' straight * to '1-0'), the state machine resets to the start until 0-0 and the * next valid codes occur. * * The biggest advantage of using a state machine over other algorithms * is that this has inherent debounce built in. Other algorithms emit spurious * output with switch bounce, but this one will simply flip between * sub-states until the bounce settles, then continue along the state * machine. * A side effect of debounce is that fast rotations can cause steps to * be skipped. By not requiring debounce, fast rotations can be accurately * measured. * Another advantage is the ability to properly handle bad state, such * as due to EMI, etc. * It is also a lot simpler than others - a static state table and less * than 10 lines of logic. */ #include "Energia.h" #include "rotary.h" /* * The below state table has, for each state (row), the new state * to set based on the next encoder output.
