Hello. My MCU is a ATSAMR21E16 of Microchip company. My board was already manufactured and there is only one MCU as CPU. I am going to look over the boot load method using USB port which is directly connected to the MCU. Of course, I have a main firmware and if you can deliver the code of USB bootloader, then I will combine them. Regards.

Hi, please check [login to view URL] and [login to view URL] This flexible pcb design has been used to provide dual sim capability to phones. I assume that it is basically filtering sim card and phone communication and when it is catching #11 or #22 input, it does the switch from sim 1 to sim 2. I need to filter something else between phone and sim card, I will explain it over chat, if you think...

Design a multifunction wristwatch that has time-keeping, alarm, and stopwatch functions. The wristwatch has three buttons (B1, B2, and B3) that are used to change the mode, set the time, set the alarm, start and stop the stopwatch, and so on. Pushing button B1 changes the mode from Time to Alarm to Stopwatch and back to Time. The functions of other buttons vary depending on the mode.
