lidar lite v3
-
Hi all,
can I connect this Lidar to M5Stick grove connector?
if yes, I need a voltage divider for SDA and SCL?tanks a lot

Technically yes as its i2c but no code will exist.

Can I try this one?
#include <Wire.h> #include <LIDARLite.h> LIDARLite myLidarLite; void setup() { myLidarLite.begin(0, true); // Set configuration to default and I2C to 400 kHz /* configure(int configuration, char lidarliteAddress) Selects one of several preset configurations. Parameters ---------------------------------------------------------------------------- configuration: Default 0. 0: Default mode, balanced performance. 1: Short range, high speed. Uses 0x1d maximum acquisition count. 2: Default range, higher speed short range. Turns on quick termination detection for faster measurements at short range (with decreased accuracy) 3: Maximum range. Uses 0xff maximum acquisition count. 4: High sensitivity detection. Overrides default valid measurement detection algorithm, and uses a threshold value for high sensitivity and noise. 5: Low sensitivity detection. Overrides default valid measurement detection algorithm, and uses a threshold value for low sensitivity and noise. lidarliteAddress: Default 0x62. Fill in new address here if changed. See operating manual for instructions. */ myLidarLite.configure(1); // Change this number to try out alternate configurations } void loop() { // Take a measurement with receiver bias correction and print to serial terminal Serial.println(myLidarLite.distance()); delay(50); }
best regards

@ajb2k3 Hi, trying the sketch above, the serial monitor say:
>nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack >nack
the same sketch on esp8266 works!!
ideas??
tnks a lot

hello, gpio sda:21 scl:22, in m5stack red grove
-
@heybin which is the difference between the red I2C (M5Stack) and the white one (M5Stick) ??
I'm trying on M5Stick....

Hi, all
connecting the lidar lite to M5Stick on grove connector makes m5Stick burn!!!this is the sketch:
#include <Arduino.h> #include <U8g2lib.h> U8X8_HAVE_HW_SPI #include <SPI.h> #include <Wire.h> #define LedPin 19 #define IrPin 17 #define BuzzerPin 26 #define BtnPin 35 int x = 870; int cm; int feet; int inches; int INCHES; bool unit = 0; #include "MPU9250.h" U8G2_SH1107_64X128_1_4W_HW_SPI u8g2(U8G2_R1, /* cs=*/ 14, /* dc=*/ 27, /* reset=*/ 33); // an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0x68 MPU9250 IMU(Wire, 0x68); //MPU9250 IMU(Wire,0x71); int status; int orienta; unsigned long pulseWidth; void setup() { Serial.begin(115200); u8g2.begin(); status = IMU.begin(); pinMode(25, OUTPUT); // Set pin 2 as trigger pin digitalWrite(25, LOW); // Set trigger LOW for continuous read pinMode(13, INPUT); // Set pin 3 as monitor pin pinMode(BtnPin, INPUT_PULLUP); pinMode(BuzzerPin, OUTPUT); digitalWrite(BuzzerPin, LOW); if (digitalRead(BtnPin) == 0) { unit = !unit; //bounce sound for (int f = 0; f < 500; f++) { digitalWrite(BuzzerPin, HIGH); delay(1); digitalWrite(BuzzerPin, LOW); delay(1); } } } void loop() { pulseWidth = pulseIn(13, HIGH); // Count how long the pulse is high in microseconds // If we get a reading that isn't zero, let's print it if(pulseWidth != 0) { pulseWidth = pulseWidth / 10; // 10usec = 1 cm of distance Serial.println(pulseWidth); // Print the distance } cm = (pulseWidth) / 10; // inches = (myData.time + x) / 74 / 2; feet = inches / 12; INCHES = inches % 12; //es x = 7% 5; // X ora contiene 2 if (unit) { stampaCM(); } else { //stampaFT(); stampaCM(); } if (digitalRead(BtnPin) == 0) { // x = 5800 - myData.time ; } IMU.readSensor(); orienta = IMU.getAccelY_mss(); Serial.println("orienta = "); Serial.println(orienta); if (orienta < 0) { u8g2.setFlipMode(1); } else { u8g2.setFlipMode(0); } delay(50); } void stampaCM() { u8g2.firstPage(); do { u8g2.setFont(u8g2_font_7Segments_26x42_mn); if (cm < 10) { u8g2.setCursor(70, 52); u8g2.print(cm); } if (cm < 100 && cm >= 10) { u8g2.setCursor(40, 52); u8g2.print(cm); } if (cm >= 100) { u8g2.setCursor(20, 52); u8g2.print(cm); } } while (u8g2.nextPage()); } void stampaFT() { u8g2.firstPage(); do { u8g2.setFont(u8g2_font_7Segments_26x42_mn); u8g2.drawDisc(63, 52, 2, U8G2_DRAW_ALL); if (feet < 10) { u8g2.setCursor(30, 52); u8g2.print(feet); } else { u8g2.setCursor(1, 52); u8g2.print(feet); } if (INCHES < 10) { u8g2.setCursor(75, 52); u8g2.print(INCHES); } else { u8g2.setCursor(60, 52); u8g2.print(INCHES); } } while (u8g2.nextPage()); }
what is this??
can I repare it?? -
m5stick grove is different, pin is gnd, vcc, 25, 13, those can be viewed from the back of the stick
