Hullo Bro, Regarding your project I have worked on many projects that utilized PIC18 MCUs. I also implemented many RS232 and RS458 communication drivers . I develop on MPLAB X IDE with XC8 and XC16 compiler. ----------------------------------------------------------------------------------------------------------------------------------------------------------------- I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. More to be discussed once you contact me . BR, M.T.

Hello! I think i know what you are looking for. I have worked with PIC18 chips. Usually RS232 has only two pins for Rx and Tx but for RS485 you need for pins since its differential communication. I am also familiar wwith MODBUS protocol as well. Let me know if you are interested. Most of the pic18s have more than 1 PWM pin. We can chose according to our necessity... Thanks!

Hello I can understand your project in which you are giving the commands over the RS485 Modbus to control your 2 PWM outputs at your desired frequency to get a sine wave. The control commands would be temperature dependent and they will be produced in a closed-loop system automatically. I am confident that your project work , both software and hardware can be easily done by me to your satisfaction. I have done similar projects before specially related to PWM control and RS485 communication as well as temperature control. I have very good experience in Microchip MPLABX and XC8 tools. I recommend you to use PIC18F46K22 MCU as it has 2 UART ports for future enhancement. I hope you will provide me a chance to do a perfect project for you. Thanks. Sincerely Naeem

Hi, My name is Cody Phipps and I am a freelancer located in Austin, Tx. I started out uploading firmware and designing PCB for six years now. I was introduced early on in college and continued to deal with Arduino's and other Atmel chip sets as a hobby during college. Once I graduated, I noticed that I was skilled enough to start freelancing with it. Given that my concentration and career is focused on power system, I usually help with creating power supplies and charging circuit for the projects I work on as well. Other thing that puts me ahead of the curve is that I am partnered with a with a product developer/PCB manufacturer here in Austin. With this partnership, I have access to a team of engineers and professionals with various backgrounds. I will be able to take your project, review it and perfect it to your specifications in no time. Please message me if you have any questions. Thanks, Cody Phipps

Hi there, I'm interested in your project. I understood your plan but it is not fully clear to design. Some information need to know first. What is the operating temperature range? What is the frequency range of sine wave from PWM signal of MCU?
