We have an existing board with 3 input switches, an interrupt input and a stepper driver connected as an output. There's also a serial D/A-converter to control the output current. The existing well running program is written in assembler. This should now be rewritten in C. We use MPLAB and ICD3 of microchip to program the device.

Hi, Previously i had worked with Microchip controller. And i had very good knowledge of Microchip controller and it's IDE. And main thing is i had also available equipment like JTAG Debugger which can be use with this chip. But problem is with hardware of the controller which you mentioned. Based on your description i can understand like, you want to control stepper motor based on different mode. In normal mode it will work based on some predefined speed. In Testing mode(Learning Mode) it will indicates only motor is working by operating it clockwise and anticlockwise based on switches. And in emergency mode it will goes at pitch position. I think pitch-position mean motor will not control it's host and End position mean stepper motor will connect to it's HOST and it will control it's HOST. By the way, it can be developed within 3 days but i can also lock the code by lock byte and fuse byte so no one can hack your device. And for this i will need your hardware, so it can be done within your requirement days. Let me know your thoughts. Thanks, Kalpesh Ramani.

I have been working with PIC microcontrollers (8, 16 and 32 bits, also DSP family) for the last 3 years. Currently using MPLAB X for development, and PICkit3 as a debugger/programmer. I have good understanding of D/A and A/D converters, and also very comfortable with assembler code. While developing the project I will make it available through a private repository from which you can track the progress.

Hi, Your projects look very interesting. I'm very keen to do it for you. As you can see I'm fairly new to Frelancer. When I will have a hardware, it will take me about 5 days to finish. Because of all that I'm willing to do this project just for feedback. I'm based in UK. I got huge experience with stepepr motors and PIC. I'm an Design Enginner with 15 years background in embedded systems. Don't hesatitate to contact me to discuss the details. Cheers
