A part of USBware: Embedded USB Software solution
USBware's protocol software stacks enable software and device manufacturers
of PDAs, mobile phones, digital cameras, MP3 players, set-top boxes and other consumer devices, to quickly and easily implement USB host and peripheral functionality.
USB has become an industry standard for connecting peripherals to PC's and laptops. The increasing need of connecting portable devices directly with each other without the presence of a PC has led to the development of the USB On-The-Go supplement.
For a complete USB On-The-GO (OTG) solution, Jungo provides a USB Host Stack, USB Device Stack,
and an OTG Controller Stack (see diagram on the right).
Background
USB has become an industry standard for connecting peripherals to PC's and laptops. The increasing need of connecting portable devices directly with each other without the presence of a PC has led to the development of the USB On-The-Go supplement.
USB OTG technology overcame the obstacle presented by the fact that USB is using a master-slave protocol, by allowing a USB peripheral to include these characteristics:
- An addition of host capabilities to enable point-to-point connection
- Dual-Role device (DRD) - the ability to be either a host or a slave and dynamically switch between the two states
- A small USB connector to fit the mobile form factor
- Low power features to conserve battery life
Specification
- Product description: USB On-The-Go Stack
- Full OTG support, including the SRP and HNP protocols as well as dynamic loading and unloading of the device/host stacks.
