    Stm32 NFC ST25R Закінчився left

    I need to write a program based on the STM32F4 microcontroller and the NFC chip ST25R3916 or ST25R3911B. The program should implement work with the phone (Android and IOS) and work with NFS cards. The program is required to be able to read data from physical cards and to transmit and receive data from the phone (NFC TAG or NDEF messages).

    We have been doing research underwater using laser equipment. The current version we are using is a simple on/off laser that is activated by a pressure switch. After using it for quite a while we now want to make laser equipment with logic capabilities by adding a microcontroller. We also want to simplify the circuit into a small PCB that’s easily integrable. Bids will be looked at and assessed on 13th Jan 20:00 GMT.

Designed PCB: Using a microcontroller to control the output state of a solenoid, opening, and closing it when certain inputs are met. The solenoid will open (inject) and close on a schedule of 2 minutes on and 2 minutes off a selected number of times & schedule of days. Ex, on and off cycle repeats 10 times, every other day. There will also be a pressure switch which will need to be closed in order for the solenoid to open, if it opens the scheduled solenoid would stop. Components: - Microcontroller (Preferably AT Mega 324A or AT Mega 168) - LCD Display (NHD-C12864LZ FSW-FBW-3V3) to show the current setting as well as the state of:...
