Hi, I am attempting to setup a TFMini-Plus to run using the I2C protocol but have so far been unsuccessful in getting it to switch from UART to I2C (Note: The sensor works fine in serial mode). My motivation to switch to I2C is that I plan to run 8 of these simultaneously on a Mega board. My setup is as follows:
Arduino Mego 2560 board
Logic Level Converter to get 3.3V to the SDA and SCL ports of the TFMiniPlus
I have attempted a few different things, but my goal would be to switch these sensors using the Arduino Mega itself as I run on a mac and cannot use the provided GUI from Benewake. Most recently I have tried sending the SET_I2C_MODE with the sendCommand function. This returns as a fail in my script. My script is attached below. I am happy to provide more details or try other things out.
Thank you for all your time and any assistance you may be able to give me!
#include <Wire.h>
#include <TFMPI2C.h>
TFMPI2C tfmP;
void set_i2c_mode()
{
if( tfmP.sendCommand( SET_I2C_MODE, 0 ))
{
// If successful, display the version number...
Serial.print( "Complete"); // and brreak out of loop.
}
else
{
// If not successful, display the attempt number
// and the error: HEADER, CHERCKSUM, SERIAL, tec.
Serial.print( "failed. "); // Display error message...
}
delay(100);
}
void setup() {
// put your setup code here, to run once:
Serial.begin( 115200); // Initialize terminal serial port
delay(20);
Serial.flush(); // Flush serial write buffer
while( Serial.available())Serial.read(); // flush serial read buffer
Serial.println();
Serial.println( "*****************************");
Serial.println( "Issue command to switch to I2C");
set_i2c_mode();
}
void loop() {}
Additionally, I have also tried your provided example scripts. Here is the output I receive from the TMFPI2C_example.ino case. I can also run my script that does serial operations without issue after attempting any of these I2C scripts. Based on my understanding, if I ever successfully switch the sensor to I2C mode I should not be able to use the UART mode.
