![]() You can also make another motor on port M2Īdafruit_DCMotor *driveMotor = AFMS. In this case, M1Īdafruit_DCMotor *steeringMotor = AFMS.getMotor(1) #include "utility/Adafruit_MS_PWMServoDriver.h"Īdafruit_MotorShield AFMS = Adafruit_MotorShield() #if not defined ( VARIANT_ARDUINO_DUE_X) & not defined ( VARIANT_ARDUINO_ZERO) ![]() I am a novice coder at best and have used the Controller example from the BlueFruitLE nRF51 Library ( Controller | Bluefruit LE Connect for iOS and Android | Adafruit Learning System) to base my controller code off. The response time suddenly becomes extremely slow, taking up to a minute at times to recognize that I have let go of one of the buttons. I have been able to write programs for each unit independently but the problem comes when I try to control the motors using my iphone and the adafruit app through the LE SPI Friend. I am trying to control these two motors with the Bluefruit LE SPI Friend. I have a v2.3 Motor Shield connecting two 9v DC motors through M1 and M4. and so we aren't at the mercy of any third party vendors who may or may not be interested in keeping their code up to date or catering to our customer's needs.I have done research and not been able to find much on the specifics of my problem. We control every line of code that runs on our modules. One of the biggest advantages of the Adafruit Bluefruit LE family is that we wrote all of the firmware running on the devices ourselves from scratch. There are plenty of BLE modules out there, with varying quality on the HW design as well as the firmware. Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them!.Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed. Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons.Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry.The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID).We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad. Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. The actual implementation of the nRF51822 readline () function is in the file AdafruitATParser. The object that controls interaction with the nRF51822 is a subclass of the Arduino Stream class, which has all the functions like read (). Really, way too long to list here!ĭownload our free Android/iOS app and you're ready to rock! Re: BLUEFRUIT LE SPI FRIEND-BASIC CHAT-ble.readline () Thank you. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. If you like Serial communication more than SPI, we also have a version that can talk UART You can use our iOS App or Android App, or write your own to communicate with the UART service. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready). With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. So what you really need is the new Adafruit Bluefruit LE SPI Friend! ![]() ![]() Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity.
