Hello, I am ready to write code for your project. I like to work with small microcontrollers like ATTiny. I checked project description and all functions seems possible to implement. As I understand, not all of 12 locations of SW1 are used, as there is only 4 working modes. It is then possible to repeat these modes as SW1 goes past 12 switch locations. If you can send me prototype PCBs this makes code developing and testing really possible. As I am located in EU, sending them back and forth is not complicated. Best regards and let me know any further details.

Hello, my name's Jorge, I am an electronics engineer with experience writing firmware for embedded devices. I have a broad experience with projects similar like yours: Getting a custom PCB (or parts), and developing the firmware based on the client requirements. I have read completely the details of your project, and four weeks is time enough to complete your project. I will agree to your condition of ending our agree if I don't deliver the first milestone in two weeks. I wrote my proposal with the milestones based on this. Please contact me to discuss any additional details of your project, I'd be glad to talk about your project in order to start shipping the parts as soon as possible. Thanks in advance for your time.

I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. I also have long experience with PCB design. I have worked with low-speed , high-speed and power boards. I use Altium Designer and Eagle, and I deliver neat layout that conforms to your dimension constraints and the manufacturing constraints. . I can show you samples of my previous work on my youtube channel and you can also go through my portfolio. More to be discussed once you contact me . BR, M.T.

I have rich experience in Atmega series Controllers, had written program using winAVR, AVRASM , interrupt driven and event driven programming methods. Also I use Atmel studio as well Project Summary - Stopwatch with two rotatory encoders one to select the mode and another to increment or decrement the values - button to start and stop the stopwatch - LED1, LED2 to indicate status - Analog input to be sampled My algorithm - I2C Interrupt Driven - External interrupt for Encoders - External interrupt for BTN as well - timer tick interrupt to update display every 10mS - Analog Interrupt to read and average it and compare it and update the display - Data processing, LEDs are done in main loop if you like contact me for more details since i have more time 100 is enough

Hi, I read the system description document, I can develop this functionality. I won't be needing the pcb. Most of the program would be pure C/C++, so the only parts relevant to the actual hardware (like the io expander, or the led matrix, etc) can be easily checked with a simple sketch. Please do message me for more details. Best regards, Robert Wallner PS. This is a new account, therefore I don't have any ratings, but you can search for my old account with username "scinova", to see my past work and feedbacks.

Hi Great project and great documentation. Browsing the pdf, spotted that on the analog buttons upper voltage would be closer to 3.75V then 3.3V, but is not big deal. Also, IS31FL3736 has linear dimming for LEDs, have you consider using that possibility? Love to work on this project, and for start I’d like to draw small algorithm, just to make sure that we are on the same page. Looking forward to work for you with you Meris
