WS2812B Without SPI

in Puck.js, Pixl.js and MDBT42 • 4 years, 9 months
Thanks for the responses, I don't seem to get it working, I know the ws2812b is rated for 5v but it should work with 3.3 as signal and 5v for vcc. I wired it to pin D30 and tested

require('neopixel').write(D30, [255,0,0])

WS2812B Without SPI

in Puck.js, Pixl.js and MDBT42 • 4 years, 9 months

Is there anyway i can use a very short strip of WS2812B (9 leds) with the MDBT42Q module i see it doesn't have SPI, but can i send a signal any other way ?

Electric skateboard remote

in Projects • 4 years, 10 months

Hey, wanted to share my project. Worked on a electric skateboard remote control. Improved alot of code from AutinumOnes inital remote. There is still alot of work todo like porting VESC UART lib to Espruino.
It features, cruise controll, accurate voltage readings, throttle indication, different modes, magnetic charging, init screen, lock / unlock.
I would really like to look at the connection strength but haven't managed that yet.

UART Library for VESC

in Interfacing • 4 years, 11 months

Yeah. Quiestion is how do i send the correct data ?
Tested this without good result;

const packLength =  E.toUint8Array("COMM_GET_VALUES").length;
const sendData = E.toUint8Array(2, packLength, "COMM_GET_VALUES", 3);
Serial1.write(sendData);

UART Library for VESC

in Interfacing • 4 years, 11 months

Here is some C code that i think does what im trying to do.

int VescUart::packSendPayload(uint8_t * payload, int lenPay) {

	uint16_t crcPayload = crc16(payload, lenPay);
	int count = 0;
	uint8_t messageSend[256];

	if (lenPay <= 256)
	{
		messageSend[count++] = 2;
		messageSend[count++] = lenPay;
	}
	else
	{
		messageSend[count++] = 3;
		messageSend[count++] = (uint8_t)(lenPay >> 8);
		messageSend[count++] = (uint8_t)(lenPay & 0xFF);
	}

	memcpy(&messageSend[count], payload, lenPay);

	count += lenPay;
	messageSend[count++] = (uint8_t)(crcPayload >> 8);
	messageSend[count++] = (uint8_t)(crcPayload & 0xFF);
	messageSend[count++] = 3;
	messageSend[count] = '\0';

	if(debugPort!=NULL){
		debugPort->print("UART package send: "); serialPrint(messageSend, count);
	}

	// Sending package
	serialPort->write(messageSend, count);

	// Returns number of send bytes
	return count;
}

bool VescUart::getVescValues(uint8_t comm) {

	uint8_t command[1] = { comm }; // COMM_GET_VALUES or COMM_GET_UNITY_VALUE

	uint8_t payload[256];

	packSendPayload(command, 1);
	// delay(1); //needed, otherwise data is not read

	int lenPayload = receiveUartMessage(payload);

	if (lenPayload > 55) {
		bool read = processReadPacket(payload); //returns true if sucessful
		return read;
	}
	else
	{
		return false;
	}
}

UART Library for VESC

in Interfacing • 4 years, 11 months
Found some useful information

Reading data is done with getter functions and callback function pointers. For example, to get realtime data from the VESC, first set a callback to your function for handling the data using bldc_interface_set_rx_value_func and then request the data with bldc_interface_get_values.

// Every time you want to read the realtime data you call the corresponding getter. // This will send the get command to the VESC and return. When the data is received // the callback will be called from the UART interface. bldc_interface_get_values();

First it complains that i have to define both tx and rx pin, then it just prints undefined once and no data is arriving.

Thanks for your answer, no luck sadly. My guess is that i probably need to write some data to get some data.
UART Library for VESC

in Interfacing • 4 years, 11 months
Hello everyone.

I really want to get some data from the VESC (Vedders electronic speed control) via UART to a MDBT42Q Official Espruino breakout board. My only issue is that i dont realy know where to begin.

There are a few libraries already written in C. Im not so familiar with C so its hard to get some useful info out of it;
LIB1
LIB2
STM32F4 C Implementation

What i do know; the VESC communicates over UART using packets with the following format:

One Start byte (value 2 for short packets and 3 for long packets) One or two bytes specifying the packet length The payload of the packet Two bytes with a CRC checksum on the payload One stop byte (value 3)

More detailed information here

I would like some help with where to start basicly, i just want to get data from the VESC with espruino.

There is a bluetooth module that i can hook on to the VESC aswell that has RX and TX characteristics pre programmed, so there is also a option to communicate via BLEUART.

VESC Source code
Thanks

Awesome thank you both ! It works like a charm.
Potentiometer overshoot

in Electronics • 4 years, 11 months

Alright, so its output is calibrated on 5v ? and because it reaches 3.3v rather quick, thats a 100% for the microcontroller ?
Now the joystick is connected to Vin which is 4.2, but you mean that it will work if i connect it to 3.3v on microcontroller ?

Potentiometer overshoot

in Electronics • 4 years, 11 months
Hello, im feeling retarded.. but when reading potentiometer(Joystick) values with the code;

setInterval(() => { console.log(analogRead(D7); }, 50);

It idles at 0.65 ish.
So when moving forward the remote goes quickly to ~1 and the overshoots and start going back. So when full throttle its at 0.76.

It doesnt really matter which potentiometer i plug in they all give me some kind of going over max value and back behavior.

Thanks,
Gustav

esp8266 Save() mqtt problem

in ESP8266 • 6 years

Hey everyone.

Having some issues with my nodemcu development board. Im afraid it could be a hardware issue (the esp8266 gets really hot).

Everything works when its freshly sent to the device but as soon as i reconnect the mqtt connection bugs out.

Working:

After reboot

var wifi;

// Mqtt Connection 
function mqttConnect() {
  mqtt = require("MQTT").connect({

  });
  mqtt.on('connected', function() {
    console.log("MQTT connected");
    // subscribe to wildcard for our name
    mqtt.subscribe(PATH+"#");
  });
  mqtt.on('publish', mqttMessage);
  mqtt.on('disconnected', function() {
    console.log("MQTT disconnected... reconnecting.");
    setTimeout(function() {
      mqtt.connect();
    }, 1000);
  });
}
function mqttMessage(pub) {
  console.log("MQTT=> ",pub.topic,pub.message);
}


function onInit(){
console.log("Connecting to WiFi");
wifi = require("Wifi");
wifi.connect(WIFI_NAME, {password:WIFI_KEY}, function(err){
  console.log("connected? err=", err, "info=", wifi.getIP());
  mqttConnect();
  });
}

I have tried different firmwares both 1.95 and 1.96
No diff.

Any thoughts?

Great job guys ! no more Meditation error ! but now i get:

{"err":true,"checksumError":false,"raw":"","temp":-1,"rh":-1}

When trying to read D22 ? thoughts.. why isnt it recieving any data..
// Edit
Tried with another Dht11 standalone board on pin D22, works like a charm.. You think my onboard sensor is broken ?
HiGrow ESP32 DHT11

in ESP32 • 6 years, 2 months

analogRead(D35) reads 0, but from what i know the soil pin is D32 and it works, displays 0.8, when i hold my fingers around it displays around 0.4 so it works.

HiGrow ESP32 DHT11

in ESP32 • 6 years, 2 months

I got the same error with both versions of Espruino.
My code is

    var dht = require("DHT11").connect(D22);
    function onInit() {
        setInterval(function () {
            dht.read(function (a) {
                console.log(JSON.stringify(a));
            });
        }, 3000);
    }
    onInit();

When a try pin D22 i get the error that i posted in the top post. Guru meditation.. When i try randomly reading pin D17 with the DHT11 module i get the answer

    {"err":true,"checksumError":false,"raw":"","temp":-1,"rh":-1}

When i do a analogRead() On pin D22 i get

E (221702) RTC_MODULE: /mnt/c/Users/rhys/esp32/edge/EspruinoBuildTools/esp32/build/esp-idf/components/driver/./rtc_module.c:554 (adc1_config_channel_atten):ADC Channel Err

=0.06298828125

Sadly i cannot follow the actual pin to the sensor premounted on the board.. But from a look at other projects they use pin 22.

I tried with both 1v95 and 1v94 and none worked. I tried just choosing a different pin aswell, and then i got

{"err":true,"checksumError":false,"raw":"","temp":-1,"rh":-1}

And if i do a normal analogRead on pin 22

>analogRead(22)

Found a few pins from a lookalike project that seems to work.
let ResetPin = 0;
let LedPin = 16;
let DHTpin = 22;
let SOILpin = 32;
let LIGHTpin = 34;

Problem now is that i try to use the DHT11 module do get the correct values but it throws a nasty looking error:

Just got myself this badboy: https://www.aliexpress.com/item/higrow-ESP32-WiFi-Bluetooth-Battery-DHT11-Soil-temperature-and-humidity-sensor-module/32818803204.html

Flashing worked perfect and wifi connection no problems. But now i wonder how am i going to find the pin to read the Temp and humidity from the dht11 ? anyone had this board before? Same as finding the correct pin to read the soil..
