connecting multiple i2c devices with single controller

Hi, Could you fix the problem? I would like to help you with it. I am Senior Electronic Engineer with experience in the design of embedded systems in real time implemented with DSP, FPGA and Microcontrollers. In my experience in the aerospace and IoT, I worked in high-speed designs and control systems, performing electronic design. I have experience connecting multiple devices on I2C bus, and solving issues relationed it. I have the ability to solve problems, fast compression of what is required, and responsibility to carry out the work in the best way. I am new using the freelance platform, but sure that I am the person who can help you.   Best regards

Hi, Theoretically, I2C bus can handle up to 128 devices with only 1 master. I think, You should check two things: 1. did you already use pull up resistor over SDA and SCL pin? 2. did that two IC have same I2C address? if you want to connect them in one I2C bus, you have to ensure they have different I2C address. I never use Quectel actually. but I2C is just I2C. the system is same on every microcontroller. I have used lot of sensor / IC using I2C bus. let me know your configuration. just message me. Best Regards, Rijal

I can do your job

Hi, I can do your work. I have experience of getting data from multiple module on I2C wire. Based on my experience I am sure I will be able to overcome the difficulties you are facing in I2C communication.

I hold master degree in instrument tech and having about 35 years of expertise in real time embedded hardware and software applications. I am specializing in IOT.

We have gone through the requirements that you have mentioned and we will help you in this. Message us for further discussion. Feel Free to contact us. Thank you!

I will make a example for you in arduino how to code and e schematic how to connect them in arduino .thank you

Hello dear I cheeked the adress of two piece, and it is ok for both. so the problem to connect both is not related to adress. I have to check with you the schematic, and the program. best regards Aymen

Dear i have 16 years experience in Embedded and PCB Designing. as per my experience this is address of I2C issue, go to internet and search for the same if you have same problem than hire me or some one who resolve this issue for you. as this is very small issue i think you don`t need to hire. If possible send me code on chatting, if its small issue we can resolve for you on chat only and may be you do not need to hire anyone. If your problem will solve after read my proposal please write comments for me. Thanks Jasbir Singh

I had 4years industrial experience in Embedded systems .... Almost all I2C sensors are interfaced.. Temperature, humidity, Ambient Light and etc...

I have used both of the I2C devices mentioned. It shoukd not take me much time to figure out the proble. Though the vontroller your using might be different, you can test my libraries for testing and I canvalidate the schematic as well.

I would like to answer your problem i was working with i2c, spi protocols in pic controllers i can clear your problem if you have ping me

Hi, I am interested on this project and I want to share my expertise with you in this project. I am an electronics engineer and IT programmer with over 15 years of experience. I do design of embedded systems and interfaces such as microcontrollers and peripherals. I had already more than 50 projects done in embedded systems, arduino, avr, microcontroller, circuit design, microcontroller coding, database systems, website developer (Proficient in PHP, SQL, XML, HTML5, HTML, CSS, BOOTSTRAP JAVASCRIPT), web research and PCB layout. Such projects are Quadcopter(a famous flying robot that is autonomous), Wifi Scanner, Power Monitoring Systems, Manguino MCU, and many more.
