  • ESP and DHT22 LOW MEMORY
    in ESP32 •
    Avatar for Frida

    Ok, time to bring the toys back.
    With this test I have set a LED to pin, active low.

    First test.

    function tt () {
  ht = {};
  //ht.pin = D0; // esp8266
  ht.pin = D12; // esp32 pico4

  setInterval (function () {
    var d = "";
    ta = getTime ();
    tb = 0;

    pinMode (ht.pin, 'opendrain');

    ht.watch = setWatch (function (t) {
      d = 0 + | (t.time-t.lastTime> 0.000050); // 50 usec (time in sec)
    }, ht.pin, {edge: 'falling', repeat: true});

    //pinMode(ht.pin, 'opendrain');

    setTimeout (function () {
      pinMode (ht.pin, 'input_pullup');
      tb = getTime ();
      console.log (tb-ta);
    }, 1000);

    setTimeout (function () {
      Clear watch (ht.watch);
      console.log ('d =' + d);
      console.log (process.memory ());
    }, 200);


  }, 3000);
}

TT ();

     
    It only gives me short pulses, and not for 1 second, as expected.
    If I remove clearWatch (ht.watch), I get a short pulse, then full pulse length and it uses all the memory.

    On esp8266 there are no problems.

    Next test.

    function tt () {
  ht = {};
  //ht.pin = D0; // esp8266
  ht.pin = D12; // esp32 pico4

  setInterval (function () {
    var d = "";
    ta = getTime ();
    tb = 0;

    //pinMode(ht.pin, 'opendrain');

    ht.watch = setWatch (function (t) {
      d = 0 + | (t.time-t.lastTime> 0.000050); // 50 usec (time in sec)
    }, ht.pin, {edge: 'falling', repeat: true});

    pinMode (ht.pin, 'opendrain');

    setTimeout (function () {
      pinMode (ht.pin, 'input_pullup');
      tb = getTime ();
      console.log (tb-ta);
    }, 1000);

    setTimeout (function () {
      Clear watch (ht.watch);
      console.log ('d =' + d);
      console.log (process.memory ());
    }, 200);


  }, 3000);
}

TT ();

    Here pinMode has been moved to after set_Watch and I can determine pulse length on LED.
    Also works on esp8266.

    And now for a workaround, so it works on both esp8266 and esp32 pico4 as I have.

    Hope this is something you can use?

    // testWatch02

function DHT22 (pin) {
  this.pin = pin;
}

DHT22.prototype.read = function (cb, n) {
  if (! n) n = 10;
  var d = "";
  var ht = this;

  // start watching for state change
  ht.watch = setWatch (function (t) {
    d = 0 + | (t.time-t.lastTime> 0.00005);
  }, ht.pin, {edge: 'falling', repeat: true});

  pinMode (ht.pin, 'opendrain'); // PB obs It sets the output low immediately

  // raise pulse after 10ms
  setTimeout (function () {pinMode (ht.pin, 'input_pullup'); pinMode (ht.pin);}, 10);

  // stop looking after 100ms
  setTimeout (function () {
    if (ht.watch) {ht.watch = clearWatch (ht.watch); }

d = d.substr (1); // PB you are a genius
    var cks =
        parseInt (d.substr (2.8) 2) +
        parseInt (d.substr (10.8), 2) +
        parseInt (d.substr (18.8), 2) +
        parseInt (d.substr (26.8), 2);
    if (cks && (((cks & 0xFF) == parseInt (d.substr (34.8), 2))) {
      cb ({
        raw: d,
        rh: parseInt (d.substr (2.16), 2) * 0.1,
        temp: parseInt (d.substr. (19.15), 2) * 0.2 * (0.5-d [18])
      });
    } else {
      if (n> 1) setTimeout (function () {ht.read (cb, - n);}, 500);
      // else cb ({err: true, checksumError: cks> 0, raw: d, temp: -1, rh: -1});
      else cb ({err: true, checksumError: cks> 0, raw: d, temp: -1, rh: -1, n: n});
    }
  }, 100);
};

  }

  var dht = new DHT22 (pin);

  console.log (dht.getName ());

  setInterval (function () {

    dht.read (function (a) {
      console.log ("Temp is" + a.temp.toFixed (1) .toString () +

             1);

    setTimeout (function () {
      console.log ("E-Flags: [" + E.getErrorFlags () + "] \ n \ n");},
               1000);

  }, 3000);

}


dd ();

// save ();

    And some outputs.

                        // temp
                        temp = (data[14] | data[15] << 8) / 10;
                        break;
                    }
                    case 6: {
                        // humidity
                        humidity = (data[14] | data[15] << 8) / 10;
                        break;
                    }

    You use the same dataset for both temp and humidity, is it correct?

    It is not only 'ESP8266', 'PICO' also has problems.

    Some tests:

    Serial2.setup(9600,{});


ERROR: *** PB *** baudRate = 9600
ERROR: *** PB *** pinRX = 255
ERROR: *** PB *** pinTX = 255
ERROR: *** PB *** pinCK = 255

{  }

    By default setup, PB0, PB1 and PB2 are not touched.

    Serial2.setup(9600,{bytesize:7});

ERROR: *** PB *** baudRate = 9600
ERROR: *** PB *** pinRX = 255

ERROR: *** PB *** stopbits = 1
ERROR: *** PB *** PB3 = 44
ERROR: *** PB *** PB4 = 55
ERROR: *** PB *** PB5 = 66
{ "bytesize": 7 }

    With this setup, PB0, PB1 and PB2 are overwritten.

    typedef struct {
  int baudRate;            /// FIXME uint32_t ???
  Pin pinRX;
  Pin pinTX;
  Pin pinCK;               ///< Clock, or PIN_UNDEFINED
  Pin pinCTS;              ///< Clear to send, or PIN_UNDEFINED
  unsigned char bytesize;  ///< size of byte, 7 or 8
  uint8_t PB0;              // insert PB
  uint8_t PB1;              // insert PB
  uint8_t PB2;              // insert PB
  unsigned char parity;    ///< 0=none, 1=odd, 2=even
  unsigned char stopbits;  ///< 1 or 2
  uint8_t PB3;              // insert PB
  uint8_t PB4;              // insert PB
  uint8_t PB5;              // insert PB
  bool xOnXOff;            ///< XON XOFF flow control?
  bool errorHandling;      ///< Whether to forward parity/framing errors
} PACKED_FLAGS JshUSARTInfo;

    In the file 'jsserial.c' and in the function 'jsserialPopulateUSARTInfo' there are:

      jsvConfigObject configs[] = {
      {"rx", JSV_PIN, &inf->pinRX},
      {"tx", JSV_PIN, &inf->pinTX},
      {"ck", JSV_PIN, &inf->pinCK},
      {"cts", JSV_PIN, &inf->pinCTS},
      {"bytesize", JSV_INTEGER, &inf->bytesize},
      {"stopbits", JSV_INTEGER, &inf->stopbits},

    I do not know what it's doing, but it returns 4 bytes for 'bytesize' and 'stopbits', like 32 bits, but in 'JshUSARTInfo' they are set up as 'chars'

    That is, 'bytesize' overwrites 'parity, stopbits and xOnXOff'.

    It's worse with 'stopbits' because it will overwrite 'xOnXOff' and 'errorHandling' as well as write in an illegal address.

    Maybe we could get a 'JSV_CHAR' to these two.

    If I'm taking a'PICO 'and using:

    Serial2.setup(9600,{});

No errors. Minified 2163 bytes to 70 bytes.

    Hope it is understandable.

    Hello @MaBe,
    Downloaded last version from 29 / 10-2018.
    Tested different things and found that 'ck' is not supported in software serial.
    One thing I figured out is that in 'serial2' when I use 'even' and I load the program again, 'esp8266' crashes. However, if I use 'Even', you can reload the program over and over again.
    Then try your software serial again without 'ck'.
    This time I use an 'uint16_t dummy; // insert PB', instead of 'char '

    PS. jeg har kun en ESP8266-01 med 512KB.
