I need to change the input from a single axis analogue joystick to quadrature output that mimics an incremental encoder AB output.

Hello! I know how to accomplish your task. This will be a simple implementation. We will take a microcontroller as a basis (most likely, ATtiny from Atmel (currently Microchip)). Using the built-in ADC, we convert the signal from the joystick potentiometer into a digital code. After that, analyzing the value, as well as the speed and direction of change of this value, we will generate a quadrature signal. As part of this project, I will provide for you an electrical circuit, a drawing of a printed circuit board, GERBER files, as well as the source code for a microcontroller. In addition, I will make a prototype. I am ready to start right now. PS I see some of my colleagues are proposing FPGA or DSP for this task ... Believe me, this is too expensive and excessive. Enough one, the cheapest microcontroller.

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I would prefer to work in milestones but cannot define these until have more details I assume as the voltage increases the speed increases. Can you give me some information about the frequency range you expect plus resolution and accuracy. Are you looking for just a paper design or a full working prototype? Best Regards Dave Lelievre

Hello I am senior microcontroller and Electrical Engineer. I have plenty of experience in firmware development. I have been a lot of Microcontroller developments. I can write the firmware based on PIC and FPGA as well as ARM and DSP. As I am an Electrical Engineer, I can design the cicuit by the Altium designer. I have used the encoder in the motor control. so I know the encoder well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I hope we can discuss more details via a private chatting. After you see my profile, you will think I have no experience. I have been developed the great whole project, and I have the actual experience. I hope you think again about me I look forward to your response Best regards.

I have already worked on similar project. But the project I worked on required BCD output. I will only make a few modifications and your project will be done as soon as possible.
