    I have an assembly program that was originally written for the PIC16F690. It takes serial data in, process a specific number of bytes, and convert it to an I2C stream to a Master. I need someone to update this code to a PIC18F that has more RAM and is much faster, and in the mean time, process three times more bytes.

    I need some assistance to design and produce a prototype simple circuit that will provide sequentially flashing LEDs for vehicle turn signal and brake indicators. This prototype will be used for evaluation and marketing purposes prior to any decision being made on manufacture.The person I"m looking for has done something similar to this before and can provide me with options for the flash sequencing, integration of multicoloured LEDs (red/amber), and particularly a good knowledge of how to design for cost effective manufacture.I envisage the finished item will have 10 sets of 3 LEDs, providing 10 positions that can be animated/sequenced.Please provide examples of similar work and I will forward you a more detailed description of the project.Thank you.

    Hi, I have an indicator that i want to get programmed. I want to link this to a database as I will be selling this indicator on a monthly subscription. So the database will be linked to my payemnt processor through some sort of API, and when the payment processor pings back (it will probably ping once a month as it will be a monthly subscription)- then it will tell the database whether to still give the member access to the indicator depending on whether they are still paying members.The indicator is specific to the forex pair it is run on. I want the parameters and code of the indicator to be hidden so no member can see how it is formulated.I understand that you will need more info on what the indicator is etc....but I first need to know that the above can work and you can give people access to my indicator and still protect the code, AND also create some sort of database that will make the indicator not work if they stop paying the monthly subscription.I am not sure which platform it should be develped on mt4 or mt5. I want it developed on the platform that most of the brokers use.thanksKumar

    Based on your profile, we have noticed that you have strong competency for Micro-controller and Bluetooth.We think you will be a great fit for our project, which involve a hardware and firmware design of a device that intended to be controlled by a mobile phone (android and iOS). The project will require a very secure approach for pairing method, proximity detection, and need for 2 way communication between the mobile phone and the hardware. No worry the app will be taken care of by another mobile developer which should make your life easier.Let us know if you are still available and willing to take on new project. If you so what would be the best time to have a quick chat.Details on the firmware/hardware will be discussed later in private messages.Hope hearing from you soon
