I am an experience electronic design engineer and have over 10+ years experience in Eagle. Over 30 years of experience in electronics and 25 years in programming. Can do this job pretty nicely so that you will have less overhead migrating your existing firmware. Thanks and do let me know if you need my service. I am ready to start now. Best Regards... Roy

Dear Juergen, Thanks for posting such a wonderful project. I am an embedded systems expert with over 20 years of design and development experience using 8-bit, 16-bit and 32-bit MCUs working on battery operated and other type of complex devices developing ultra-low power designs. I have worked with PIC16/PIC18, dsPIC and PIC32Mx series MCUs using MPLABX IDE and PICKIT3 tool. I am a resourceful Engineer with access to all PIC hardware (including 18F family). I would redesign/modify the Schematics as per your requirements and provide you a working code. I have full understanding and development experience of USB Classes (CDC/HID tec) and Stack for it. Regards Talha

I am an electrical engineer and interested in your project. I have read the description of your project. Kindly send me text to discuss the project in details. Thanks

We are a team of Electrical and Electronics engineers and we are Excellent in the following areas: • Embedded C Programming. • VHDL/Verilog • Microcontroller like Arduino, Raspberry Pi, FPGA, AVR, PIC and STM32. • IDEs like Keil MDK V5, ATmel studio and MPLab XC8. • PLCs / SCADA • PCB Designing-Proteus, Eagle. • Multisim • IOT Technologies like Ethernet, GSM GPRS. • HTTP Restful APIs connection for IOT Communications. Also we have good command over report writing, I can show you many samples of our previous reports. Kindly consider us for your project and text me so that we can further discuss specifically about your project's main goals and requirements. We can deliver your project efficiently at a time. If you choose me, I think you won't regret. Best Regards. Also we have good command over REPORT WRITING, We can show you many samples of our previous reports. We can discuss further details in the message box.

You are doing this wrong! You need to consider your layout before you commit to certain pins. For example, if I assign the 3 push buttons to pins 39-41 and your layout requires that the TQFP be oriented such that pins 1-3 are closer, then you just created a layout nightmare. The layout with the 28 pin DIP device was fairly simple but you now have many more connections/routes to do. A little advanced planning will make your life a lot easier later on. The I2C is fixed and cannot be changed but everything else including SPI2 is remappable. Regards, Jim

Dear Client, I have seen the pdf attached. For this i need the schematics of the older PIC18 connection as well. Then i will transport and refer new connections pins of the new controller as you referred. Untouched =USB -ICSP =IR Receiver receiver module For new controller I have see you want to connect 5 digit display. Temperature sensor , Motor. Once i see the new controller pin definition i will refer it to you. SPI, I2c and motor driver connections are not a problem. Once you follow up with the project, I will refer the pins of the new controller after checking definitions for respected chips. Hope to continue with you on this project. Looking forward to hearing from you. Thanks Sr. Lead Product Engineer Fahad Naveed Khan

Hi, we are very experienced and dealing in design and development of electronics since last decade. We can share pics and videos of our past developed projects with you also. For you, we will review your circuit and upgrade it. even we will test everything if you want. Contact us and we will discuss everything in detail. regards, Muhammad Faraz Khan AcademicsAssistant Team
