Hello everyone,

Thank you all for your help, I finally reached the solution. This forum is truly special.

I think the problem was in the chip or pcb. Maybe the probes of the scope were corrupti ...

Hello Prince,

I tried it the way you said and it behaves the same as the code I last shared. When I examine it with Scope, the sensor sends the response correctly, but there is still a problem in t ...

Ttelmah,
Based on what you said, I made some changes to the code. When I modified the code below, I was finally able to read the distance data from the sensor with the scope.
But I cannot read thes ...

Hello everyone,

I checked the message signals with the scope.

i2c_start();
i2c_write(VL6180_address); // 0x52
i2c_write((0x0018 >> 8 ) & 0xFF);
i2c_ ...

Hello PrinceNai

Since I have an unfinished business with those TOF sensors, I tried to translate the code from an ST appnote. There are some functions to read and write to the chip and to do range ...

Hello
I don't know how to change the speed of the I2C or what speed I'm currently running it at.

#use i2c(MASTER, FAST, SCL=PIN_C3, SDA=PIN_C4)

I tried both fast and slow here, the resu ...

Hello ttelmah.
I’ll try what you said first thing tomorrow morning than I’ll feedback here.

For now I wonder something. Do you see any mistakes on my code? Do you think this is the right way ...

My main code is very long, so I am only sharing the part relevant to this task and the definition codes above.

#include <18F452.h>
#device ADC=10
#FUSES NOWDT

Hello temtronic

Does it work without the I2C MUX ??

I tried it witout i2c mux and the result is same.
I2c scan finds it but still I can not communicate.

I suspect it's a 3Volt sensor and ...

Hello everyone, I am working on a project and in this project I need to read the VL6180x distance sensor through the TCA9548 i2c port multiplexer but I have not been able to achieve this yet.
I am su ...

Yes this is RS485 I am using SN75176.

As far as I know, when I configure RS232 to the PIC and use it with an IC like SN75176, I create a proper RS485 communication. Please correct me if I'm wrong. ...

Hello Ttelmah, temtronic. Thanks for quick replies.

#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, parity=N, stop=1, bits=8, RECEIVE_BUFFER=128, ERRORS)

Hello everyone.

I am trying to provide RS232 communication with Pic18f452 chip. With the code I shared below, I can send data to the serial port via Putty, but unfortunately, when I try to receive ...

This is wrong. T isn't a 32 bit variable. You will receive 4 separate 8bit characters in 4 separate transmissions that you need to store in a buffer somewhere and later display them.

If you car ...

Hello

Now the three characters thing comes from the size of the FIFO in the
serial receive. The chip has a single RX receive register, and two characters
of FIFO. So 2.9999 characters can be rec ...
