Fred Eady is the owner of EDTP Electronics, which was established in 1988 following the publication of his first magazine article. Since the formation of EDTP Electronics, Fred has written thousands of magazine articles. He has written for all of the major electronic magazines, including Radio Electronics, Electronics Now, Nuts and Volts, Servo, MicroComputer Journal, and Circuit Cellar. To date, he has authored four books and contributed to a fifth. He currently works as a PIC microcontroller consultant and is a Microchip Authorized Design Partner. Fred also authors monthly columns in Nuts and Volts and Servo magazines. His customers include machine shops, specialty startup companies, medical machine manufacturers, coin-operated device businesses, and various other research and development companies. He has a very close working relationship with Microchip Technology, the manufacturer of PIC microcontrollers, and has taught Ethernet and WiFi classes at Microchip's annual Masters Conference.
The goal is to contact an email server and send an informational email to a remote device at the appropriate moment. To accomplish this, we will need to code an SMTP application that our WIZ850io and ARM microcontroller can successfully execute.
The WIZ850io module offloads the internet access and wired Ethernet tasks from our ARM microcontroller. An ioLibrary (internet offload library) is provided by the WIZ850io manufacturer. Our mission today is to adapt the WIZnet ioLibrary and WIZ850io module for use with our ARM microcontroller.
Our IoT design contains a pair of EEPROMs in its nonvolatile memory subsystem. One of the EEPROMs is a specialized IC that contains a factory-programmed, globally unique 48-bit node address. The other EEPROM is a standard 256Kbit device. Both EEPROMs require an SPI communications portal. Today’s...
The ARM microcontroller’s second USART will be used to interface to a smart LCD touch display. Today, we will generate code to enable the USART and establish a logical bidirectional communications channel to the touch display.
We begin by translating our hardware components into logical elements. Data paths to and from the ARM microcontroller will also be defined. We will use a J-link PRO for debugging and programming. An alternate debugging portal consisting of one of the ARM microcontroller’s USARTs. An FTDI TTL-232R-...
Today’s lecture is heavily geared toward coding sensor firmware. We will utilize the resources of MikroElektronika’s largest ARM development board and mikroC PRO for ARM to create firmware for the newest sensor-laden click boards.
