Error = Wire.endtransmission()

With luck you'll be able to find the actual vendor and in addition to the data sheet you may able to find application notes there as well. changes made from the original code:(1) The ino source file (original for Arduino) used is athttps://raw.github.c...o/sl018demo.inoOnly thing modified from the above source is#define TAG 2in line 18.

Only one I could find were from China. twi_writeTo do not return property errostate. At least it isn't a hang. Typically 4.7 k from both to +5 V. https://www.arduino.cc/en/Reference/WireEndTransmission

Firstly check all your I2C addresses with same code: #include "Wire.h" byte start_address = 0; byte end_address = 127; void setup() { byte rc; Wire.begin(); Serial.begin(9600); Serial.println("\nI2C Scanner"); Serial.print("Scanning I2C bus Register now! This was done using the i2c_t3 library. Can you please check with a voltmeter if both lines are at 3.3V while endTransmission() is stuck?

  4. If false, endTransmission() sends a restart message after transmission.

In general, have others seen issues in using PlatformIO with the Arduino standard libraries? There are multiple Teensy modules, one per zone which will have different temp and humidity settings. Perhaps the shown glitch is causing some confusion? What you can try is to see if things will start working when you connecttheVCC of the module to 5 volt. 5 Volt is available on the test pins next to

Would Arduino want to incorporate it into their code? Why are static password requirements used so frequently? Ideally there would be a "stuck bus" code, but maybe this happens so rarely it isn't useful information. share|improve this answer edited Jun 13 at 12:23 Ricardo 2,4041148 answered Jun 12 at 15:30 Mark11 1 I have added a link to the original author and removed the

OK, I got another Teensy3 (COM 17) hooked up to nothing with pullups and it is failing but returning error 2, NAK on address, which is correct. Do not that if the SL018 puts 5 volt on the I2C lines that this might damage the MSP430.

At that point I got an ack from my device and nacks to all others. How to respond to your boss's email about a coworker's accusation? I'll investiage further.

I'm using an Arduino Uno (for the time being), a Bluetooth HC-05 module and an MPU6050 accelerometer.

So we check all return values so that we know we can believe sensor data, and that we are properly driving heaters and lights. Share This link has expired. Also, it does not display Nunchuck ready on Serial Monitor since it is written after nunchuck_init() has been called. Another blue one standing is a bluetooth, again nothing to do with this..

The unpowered portion would of course lose its pullups, so that needs to be considered. But does anyone bother to check it? Do you have pullup resistors connected to Teensy 3.0? I think the act of reading the status register during TWI_TransferComplete() will reset the NACK flag in TWI_SR.If that's really the case, then TWI_FailedAcknowledge() will never trip.I've spun my own where
