This page describes some common configurations when using a CC254x in combination with an external MCU.

Overview[edit]

Network Processor[edit]

The HostTestRelease project (included with standard BLE SDK) is the standard BLE Network Processor application. It can be loaded on the CC2540 or CC2541, with the any of the following used as a network processor interface:

1. UART
2. SPI
3. USB CDC virtual UART (CC2540 only)

More information on the HostTestRelease project can be found in the CC254x BLE Software Developer's Guide (http://www.ti.com/lit/pdf/swru271). An overview of the HCI command protocol can be found in the TI BLE Vendor Specific HCI Guide, which is linked from the Windows Start Menu after you have installed the SDK.

For applications which only act as a GATT client and do not need to act as a GATT server, this is an ideal choice.

Network Processor GATT_DB_OFF_CHIP[edit]

The HostTestRelease project has an option that can be enabled by including the preprocessor define 'GATT_DB_OFF_CHIP' to the project configuration (under compiler settings). By adding this define, the network processor will be built such that any GATT services are maintained by the external MCU. This includes handling of all peer GATT requests to read, write, and discover services and characteristics.

Cc2540 Driver Arduino

This option provides for maximum flexibility of the GATT server by the MCU; however the code required on the external MCU is fairly complex.

More information on this type of setup can be found here: http://processors.wiki.ti.com/index.php/LPRF_BLE_NPGATT

Network Processor Custom[edit]

Rather than using GATT_DB_OFF_CHIP, another possibility is to manually add your GATT profiles to the HostTestRelease project, and rebuild the project with the services integrated into the network processor. This reduces the complexity of the external MCU code; however it requires the ability to add custom commands to the network processor in order to allow the external MCU to manage the data in the GATT services.

More information on this type of setup can be found here: http://processors.wiki.ti.com/index.php/BLE_HostTest_Add_Cmds

Stand Alone App with Serial Interface[edit]

Instead of using the HostTestRelease network processor project, another option is to take one of the existing single-chip projects included in the BLE SDK (e.g SimpleBLEPeripheral, HeartRate, RunningSensor, etc...) and modify it to include a 'UART bridge' or a 'SPI bridge', giving the external MCU the ability to communicate with the CC254x.

In addition to creating the brige using the HAL UART or HAL SPI drivers, a communication protocol must be established, allowing the external MCU to send commands to the CC254x (e.g. start advertising, send notification, etc...). It also must allow the CC254x to send event to the external MCU when specific actions occur (e.g. connection established, connection terminated, etc...). For many applications this protocol can be very simple and just consist of a few key commands and events.

This section is a quick guide on how to start using usb ports on TI platform with supplied pre-built binaries. Please refer to USB Quick Start

The USB User's Guide provides information about

• Overview of USB hardware and software
• Supported linux driver features for USB host and device mode of operation
• The Linux USB configuration through menuconfig. Please refer to USB configuration

USBSS Overview[edit]

• The USB subsystem includes

• Two instances of USB (Mentor Graphic's USB2.0 OTG) controllers. Each MUSB controller supports USB 1.1 and USB 2.0 standard.
• CPPI 4.1 compliant DMA controller sub-module with 30 RX and 30 TX simultaneous DMA channels
• CPPI 4.1 DMA scheduler
• CPPI Queue Manager module with 92 queues for queuing/dequeuing packets

• Interfaces to the CPU via 3 OCP interfaces

• Master OCP HP interface for the DMA (for data transfers)
• Master OCP HP interface for the Queue manager (to manage CPPI descriptors)
• Slave OCP MMR interface (for CPU to access USBSS/MUSB registers)

• Signals the standard Charge Pump (part of EVM BOM) for VBUS 5V generation

MUSB Controller Overview[edit]

The salient features of the MUSB USB2.0 OTG controller are:

• High/full speed operation as USB peripheral.
• High/full/low speed operation as Host controller.
• Compliant with OTG spec.
• 15 Transmit and 15 Receive Endpoints other than the mandatory Control Endpoint 0.
• Double buffering support in FIFO.
• Support for high bandwidth Isochronous transfer
• 32 Kilobytes of Endpoint FIFO RAM for USB packet buffering.
• Interfaced with CPPI4.1 DMA controller with 15 Rx and 15 Tx channels (for each usb controller).
• Defer interrupt enable feature is supported for each packet descriptor of cppi-dma.

Mentor graphics controller driver (or MUSB driver) [edit]

The MUSB driver is implemented on top of Mentor controller IP which supports all the speeds (High, Full and Low). AM33XX USBOTG subsytem uses CPPI 4.1 DMA for all the transfers. The musb driver conforms to linux usb framework and supports both PIO and DMA mode of operation. The musb host controller driver (HCD) binds the controller hardware to linux usb core stack. The musb device or gadget controller driver binds the controller hardware and specific gadget driver (filestorage, cdc/rndis etc).

Linux USB Stack Architecture [edit]

As shown in the figure, linux usb stack is a layered architecture, with musb controller at the lowest layer, the musb host/device controller driver binds the musb controller hardware to linux usb stack framework. The CPPI4.1 DMA controller driver is responsible for transmit/receive of packets over the musb endpoints.

• The Mentor USB driver can be built as module or built-in to kernel
• Support both PIO and DMA mode (The DMA mode not applicable for control endpoint)
• Support two instances musb controller in otg mode (both usb0 and usb1 controller in otg mode. This will allow host or device operation on each port simultaneously.

The driver supports the following features for USB Host (AM33XX)[edit]

The driver supports the following features for USB Gadget (AM33XX)[edit]

The driver supports the following features for Dual host/gadget (AM33xx)[edit]
