Binho Nova Click

How does it work?

The Binho Nova Click board™ was designed for ultimate flexibility with multiple ways to control and interact with it. It features two female 1.27mm 2×5 connectors suitable for connecting the Binho Nova Multi-Protocol USB Host Adapter depending on the desired interface. The connected Binho Nova Adapter is powered by its USB connection to the host PC and provides downstream power to the Binho Nova Click board™. Additionally, two power jumpers labeled as 3V3 and 5V are used to supply the host from the connected Binho Nova Adapter. It represents a perfect solution for manual testing during firmware development and debugging, automating hardware testing, and validation.

Binho Nova USB Host Adapter has 3 modes of operation: Master, Slave, and Monitor/Debug. By default, it communicates as a Master device, while the Slave device support is coming soon and will be made available to all existing devices via a firmware update. Thanks to the stacking headers that this Click board™ has, there is the possibility of connecting any Click board™ with the Binho Nova Click board™. In this way, it is possible to use the USB Host Adapter in a Mode that would monitor when the MCU communicates with additional Click while “sniffing” communications and protocols.

The Binho Nova Click can establish communication with MCU using several different communication protocols. It can serve as an SPI bus controlled device, with a frequency between 500kHz and 12MHz and with all 4 SPI modes are supported, or can serve as an I2C bus controlled device that supports clock frequencies from 100kHz up to 3.4MHz that covers all common operational modes (Standard, Full-Speed, Fast, and High-Speed). In addition to using these two communications, it also supports communication as a UART pass-through, with a maximum baud rate of 1.000.000bps for the data transfer.

Some Binho Nova connector pins can be assigned to other, related or unrelated, purposes such as GPIO, interrupt, PWM signals, or analog input/outputs. In that manner, two onboard jumpers, labeled as AN and PWM, are used to designate which pin from the Binho Nova connector is connected to the AN pin or PWM on the mikroBUS ™ socket. The default state of AN jumper represents enabled SPI communication while optionally provides the ability to use ADC/DAC, where SPI is not active. On the other hand, with the PWM jumper, the default state is enabled I2C and UART communication, while the optional state provides PWM where the UART is disabled.

This Click board™ features two enable jumpers used to supply the host from the Binho USB Host Adapter. The presence of an active power supply is visually detected by a green LED diode labeled as PWR. In the case of using the Binho USB Host Adapter in Slave or Monitoring/Debug Mode, these headers need to be removed. Only when Master Mode is used and is necessary to power the host headers should be left on the Click board™.

NOTE: The 3.3V or 5V jumper should only be populated when the Binho Nova Click is used in a standalone configuration. In any other configuration or setup, it is essential to remove these jumpers. Having both power supplies enabled simultaneously can lead to operational and functional problems. Adhering to these instructions will ensure proper functionality and avoid any complications arising from conflicting power supplies.

SOFTWARE SUPPORT

Mikroe does not provide software support for this Click board™ in the form of libraries and functions but only offers its users an example code showing the proper usage. The software support is provided by Binho, so please visit the Mission Control Software, which provides an easy-to-use GUI interface for your Binho Nova Multi-Protocol USB Host Adapter to get the full software support.

The example code of the Binho Nova Click board™ is performed via UART communication, and consists of a few simple steps that echoes strings that are entered.

• 1. Place “Binho Nova Click” into mikroBUS™ socket 1.
• 2. Insert the “Binho USB Host Adapter” connector into the “Binho Nova Click” I2C/UART slot.
• 3. Start the “Mission Control Software” application.
• 4. Connect “Binho USB Host Adapter”.
• 5. Activate UART protocol with a UART rate of 115200bps.
• 6. Send some string down the UART protocol, and if everything is in the correct order, it shall be echoed back.
