I need to have an ATTiny441 or ATTiny841 processor based project which has 2x UART inside to convert a data stream coming to one UART at 9bit, odd parity and 2 stop bit (9O2) to output on other UART at 8bit, odd parity, 2 stop bits (8O2). 9th bit is discharged and not in use (lost on transition) Baudrate on both UARTs is 9600 Data coming in is TTL level and data goingout is TTL level. Also there must be presented schematics how to connect all, how to program it and which oscillator to be used in final HW design.

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Hi. Used to do bridges like this. With some protocol convertion also. Is it 1 dirrection or 2? I can program, design pcb, provide prototype if you need. Give more info and lets talk.

Hi, I have experience for 15+ years in electronics/embedded development. I have several years of advanced AVR/arduino development, including library development from scratch. Practically all Arduino AVR boards used, like: 2009, 2010, UNO, MEGA, NANO, MICRO, MINI, DigiSpark (ATTiny), etc. Several shields used like Ethernet (W5100, ENC28J60, etc.) with various IP protocols implementation, various graphical TFTs with and without touchscreen and various BUS types (parallel, SPI, I2C, etc.), all kinds of sensors and buses, serial and parallel memories, etc. I recomend for you project using the arduino framework for simplicity to replicate and program the MCU on your side once completed on my side. If you require, I can also use AVR Studio / Atmel Studio instead. I don't have any ATTiny441/ATTiny448, but in case you award me the project, I can get some that should arrive in less than a week. Meanwhile I can work on the firmware and when the MCUs arrive, I'll test it out and debug if needed. For the firmware requirement itself, converting a "9O2" to "8O2" UART communication, I don't think I'll have a problem with that, as I have already implemented similar features in several projects before. From what I got in your description, the translation only needs to be from one UART at "9O2" to the other at "8O2" (discarding 9th bit), but I can also implement bidirectional translation if needed. If you are interested in my bid, feel free to contact me. Regards, Carlos.

Hello, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . I have sow your requirements , and i can do it in a very short time , Attiny is Arduino compatible and will be very simple to code there . I have made in the past a lot of translators for UART , same bandwidth and bandwidth changers , i can develop your product in a very short time . I can even make you a prof of concept full deployed and ship to you in Slovenia , but this will cost another 100 Euro (professional PCB + soldiering + shipping). I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteurs (+simulation). Derivable on the project : Wiring diagram for prof of concept . Schematic design PCB Design Gerber files for manufacturing MCU code explained every line . Regards, Andrei

I would want to source the two parts (plus some supplies) in order to provide an operational solution. That will take one day to visit the local market and procure the items. After that, a couple of days to write and test the firmware. It should be fairly simple. Do you need me to make the PCB as well?
