We at PDI are a hardware and Firmware design house in the states. We focus on Hardware design and are looking to develop relationship with firmware and software designers. The following is the beginning of an on going project.
PROJECT Microchip PIC32MX695F512H 32-bit micro controller
MPLAB X and Harmony experience A MUST
Winc1500 WIFI Transceiver module
This project is based on the WI-FI Demo Board from Microchip. Source code for this Demo board is provided along with running Code for this specific target board. functioning code to run 3 A/D inputs, digital water level inputs and control of two pumps and fan already working. I made sure it compiles and runs with the following tool chain:
XC32 1.42 or higher
Harmony 2.04or higher
Free RTOS and WIFI driver working
Using MPLAB X IDE v4.0 or higher
All currently available free for download from Microchip
Our goal is simply to modify this firmware by adding a functional WIFI interface and WEB page to the Using the WINC 1500 WIFI Module. code for 3 A/D inputs for current sensing and a IIC port to interface two humidity sensors. A functional relationship between these two humidity sensors and time will drive an output pin which will control a fan.
An additional digital water level sensor input will also activate two pumps in a simple functional relationship. Current in both pumps and fan will be monitored with ac current sensors (Hall effect style) with the three A/D inputs. The hardware will be handled by me and is complete. The WI-FI Demo board makes a good development platform. The output will displayed on the WEB page provided by the DEMO board (AD HOC) network can be used for development.
Successful candidate will have experience using MPLAB X & Harmony, and a popular Free RTOS that runs on the PIC32 and many other microcontrollers. Using Harmony framework; all the low level drivers are done for us function calls can be made for IIC interface , A/D interface, and WIFI interface. If you are familiar with this WI-FI demo boards, RTOS and especially the WINC 1500 WIFI module you should have very little issues completing this task in 1 to 4 weeks. Documentation of each function you write is very important. I should be able to understand your code and modify it as you may not have real sensors for development purposes but that can be your choice. Currently I have code running for all sensors except the the IIC Humidity interface. You should have the following qualifications.
* Good communication and documentation skills in English
* and understanding of TCIP networks and worked with the Winc 1500 WIFI modual
* a desire to complete the work on time ans an efficient manor
Experience with PIC32, harmony, & Free RTOS
