Hey all I am wanting to get an IC that allows me to do the following: - Have 8+ inputs - Have 8+ outputs - Ability to take any input # and direct it to any output # The latter bullet there is the main goal. So in the image example above say that I needed the following examples: Input 1 to Output 4. Input 3 to Output 1. Input 5 to Output 3. Input 4 to Output 2. Input 6 to Output 6. Input 2 to Output 5. ...and so on.... What I would be hooking up to the input would be either Ground, 5V or 3.3V which would need to output the same as its input. Note that I plan on using an Arduino so if the IC requires interaction from the Arduino in order to switch the outputs then I will have the means to do so. I would also be interested in just using the FTDI ft232r to interact with the IC. I will need to be able to use all of the inputs and outputs at the same time. Example: Input 1 --> Output 4 (5v) Input 2 --> Output 1 (RX) Input 3 --> Output 5 (TX) Input 4 --> Output 2 (3.3v) Input 5 --> Output 3 (gnd) I will be using a FTDI ft232r chip and the RX/TX lines will differ depending on what board is being used to program it using the FTDI What I am looking to accomplish is taking this layout (see attached image) and connecting those pogo pins to the multiplex/whatever in order to allow for different pcb models that have different pin layouts in order to flash firmware to them using the FTDI. Hopefully knowing that allows you to understand the overall design of what I am trying to do.

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) I understand logic of thing you want. There are some questions about how to "set" pairs input-output. Sending some commands via serial obviously. Protocol? I see this as a pcb with a mcu, power regulator, output drivers and buffers for connecting your ftdi - everything needed to implement your logic. Plus software to implement input-output logic and communication through serial with your ftdi. What are outputs? Some low current logic? Lets talk. Bid is not final due to lack of detailes for now.

Hello. Greetings of Peace! Thanks for inviting me to the work. I have great experience in developing custom electronics systems. I have developed an automation for a solar plant and have created many other industrial solutions. I have also won World Arduino UNO Wi-Fi contest for developing pressure regulatory system using custom designed Arduino. Thus, I can give you one-stop solution from prototyping to manufacturing. I would like to have an opportunity to work with you and would love to discuss your requirements in detail. Please have a look at my portfolio for my detail work. https://www.freelancer.com/u/krunalbhongade.html Thanks and Regards, Bk Krunal

This is not a bid but a hint for you: there are many ICs available that perform this function, for example MT8809. Please check the datasheet and you're ready to go - just remember that the maximum current that this kind of chips is quite small, just around +/-15mA or so. Cheers, Anh

Hi Dear, I was reading your proposal, and I can make your job exactly as you need. I'm electronic engineer with +15 years of experience. I'm very resposible person and I could help you when the work is complicated because I have tools to solve the problems and I'm too proactive. I can make it with standard logic IC or with a uC, we can chat about what you preffer. Between each stage, we will chat about the advance. Please any question, feel free to contact me. Best Regards Eng. Juan Manuel Garin

hi, I'm Ganapathi I have experience in ATmega Series both in Assembly and C I Suggest using Atmega328 controller, we could have around 20 Pin(10-Input/10-Output) excluding RX and TX Also you use CH340g or FTDI controller to program the controller just like arduino you can change pins using Commands in Serial communication or if i have time i'll develop a GUI to select and program the controller

Hello Ok no problem but i need a bit more info since you are going to use Arduino , what is the best way you would like to use for communication , there are multiple ways for example * Direct address injections using binary & control pins , Requires 10 pins [ 3 for input selection , 3 for output selection , 2 for flow control , 1 reset , 1 Cs] * I2C communication & Reset , CS Pins What is the preferred PCB Package ? Are you going to prototype this & make PCB + PCBA , or you need something to use on test board [DIP Package] ? What are the other components you need on this circuit ? My offer includes the following 1- Components selection 2- Schematic + Layout + Production files (Gerber files) 3- Prototyping assistance & choosing the best factory & providing suppliers for each items **** No High current signals is valid , only logic level signals
