we have an specially designed embedded computer which is communicating with a standard industrial modebus flow meter layer is already solved at basic levels. Currently we are able to read some values but we would like to improve firmware of our computer to add new features according to Modebus protocol document. Main software is written in C with Keil Compiler for 80C51 8-bit micro controller family with extended memory 96 kB Flash with 2 kB RAM of NXP. Due security reasons we will give certain parts of main program and want freelancer to create or improve codes. Please also note that : - bidders need to sign NDA. - bidders should accept to use C not other language like C#, Basic, Assembler etc. - bidders should have experience in embedded devices firmware programming.

multiple experiments to cover most of the functions of the 80c51 DAC,ADC ,lcd or 7 segment,switches ,sensors ,led's. (all external componets must be easily found in a electronics store) step by step instructions so someone can follow to built each of the experiments schematic diagram and circuit diagram report :abstact, background theory,general analysis ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details. Should a dispute arise and this project go into arbitration "as is", the contract's vagueness might cause it to be interpreted against you, even though you were acting in good-faith. So for your protection, if you are interested in this project, please work-out and do...

I am looking ofr a C/C++ program that will make a philips 80C51 microcontroller Monitor the following items, PIR detector, Motion Detector, Microswitches and operate a voice recording circuit and 110dB siren and immobilizer circuit.

Title: Ethernet Connectivity Option for Consumer Audio Product Programming: We are seeking assembly language programming for this application. The basic circuit design is not fixed yet, but will most likely be based on the 80C51 microprocessor with the ConnectOne () iChip for a hardware TCP/IP stack. There will be two user interfaces: 1) A web browser based interface with at least a setup page and an operation page. The setup page will allow setting the TCP/IP network properties (ie- Dynamic or Static IP, IP Address, IP Mask, etc.). The operation page will show the current status of each amplifier channel (Off, Active, Failure), the temperature of each amp channel, and the overall amplifier status (Off, Normal, Failure). There will also be 8 toggle buttons to turn each channel
