Hi,dear! I am quite interested in your project - 'UART Microchip RS485 check code problems sometimes'. :) I am a skillful software developer who has rich experience in this field. If you contact me, you and I will be happy. Thank you in advance. Skills: C Programming, C++ Programming, Electronics, Microcontroller

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the field and holds multiple degrees in IT , Electronics Engineering , Mechanical Engineering and Applied Sciences. As a full time freelancer I have my own mechanical prototyping workshop ( PCB Fabrication , 3D printing etc) and electronics testing lab.

Hola buenas tardes, Yo puedo ayudarlo a solucionar sus problemas en el código del PIC o también si el problema proviene del hardware. Soy ingeniero electrónico con mas de 15 años de experiencia programando microcontroladores y diseñando hardware. Como puede ver en mi portfolio, he desarrollado sistemas completos con PIC, de ahí que conozco muy bien las limitaciones y problemas comunes con esta tecnología. Si tu me contactas por chat y envías el código podremos comenzar a trabajar para solucionar el problema cuanto antes. También puedo hacer una revisión del PCB si tu deseas. Cualquier inquietud, por favor contactarme. Saludos. Ing. Juan M Garin

Hi, I am Embedded System Developer. I have experience of working with Microchip controllers. If possible for you send me the code. Let me have a look and see what we can do improve it. If you have any questions for me please ask here. Happy to discuss here.

We have a production capacity to support international quality standards of production. We hence request-fully submit our proposal for your evaluation and reassure you of our quality and promptness. We also are willing to sign a long term freelancer support contract for your future needs as well. Awaiting your response. Regards, Mihir

Hi We are team of experts having 6plus years pf exp in embedded systems,IoT,pcb designing and prototyping. In rs 485 communication we alredy given the genrators monetring systems throuh mod bus communication and send the data to server through gsm. Waiting for your rpl. Thanks

I am Senior Embedded Systems & C/C++ developer. Developer expert on VC++, Eclipse Mars for C/C++, gcc,g++ in Win and Linux. OpenGL, OpenCV, Cuda. Developer expert on low level programing on C/C++. Expert on PIC, ATMEL, ARM Microcontroler and Arduino. Several years(10) working with PIC microcontrollers, MPLAB and MAPLA X IDE. The problem is surely the configuration of microprocontroller records.

Dear As I am a senior software developer, have rich experience with various application development using C#, VC, VB.Net, NodeJS, Matlab, and python If you are interested with my proposal, please let me know it. I hope to work with you on this project. Thanks.

Hi. i have good experience in PIC . i have done almost similar project on freelancer that was ibutton communication. i have used usart and i2c for pic to pic and ibutton to slave communication respectively.

Hi, Experience in PIC based project. We designed similar product based on PIC32. Read data over RS485 and send it to server over MQTT. Experience in embedded more than 6+.

Hope you are doing great. I am electrical engineer with specialization in embedded software and hardware design please feel free to contact me

I can do it...

Hi, I am interested to know more about details of your problem so I can tell how exactly I can solve it. I have already worked with different micros including PIC. As you may know, UART is used very often in microcontroller projects. I can make it work. Ps. I proposed max budget at the moment but I can modify it regarding the level of work that it is needed.

I am suggesting that you replace the microcontroller from PIC16f1939 and use PIC18 controller PIC18F66K80 FAMILY - pin compatible with PIC16f1939 , and replace UART RS485 with CAN BUS chip MCP2551-I/P 8-pin. PIC18F66K80 FAMILY is pin compatible with PIC16f1939 I have the complete source to implement your application with CAN bus. I can implement your application in a very short time comparison between CAN and RS485 Feature RS48 CAN ----------------------------------------------------------------------- Required interface UART CAN controller Supported ISO model layers Physical layer Physical layer and data link layer Detection of data collisions Not implemented Yes, CSMA/CR Maximum transmission rate 10 Mbit/s (up to 12 m) 1 Mbit/s (up to 50 m) Maximum bus length 1200 m (at 100 kbit/s) 1600 m (at 50 kbit/s) Supported Bus arbitration principles Master/Slave or Token Ring Multimaster and all principles, which can be derived from that like Master/Slave or Token Ring Maximum data amount per frame Unlimited 8 bytes Examples of popular protocols Modbus RS485, Profibus CANopen, DeviceNet, J1939 CAN is very powerful communication, only two wires.
