B4RLibraryB4R other hardware [READ/WRITE]

rXDM - Set Analog Resolutions [Read/Write] in Seeeduino XIAO and Arduino Due, Arduino Maker

This b4xlib library is indented for use with the boards Seeeduino XIAO, Arduino Due, Arduino Maker. This is because the setting of analogReadResolution and analogWriteResolution function is available only in these boards. IT WILL NOT WORK WITH OTHER BOARDS.

rMCP_CAN library

CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools and as an automotive diagnostic bus. This CAN-BUS Shield adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver to give your Arduino/Seeeduino CAN-BUS capability. With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device or data logger.

B4RLibraryB4R LED

Update to library 4 new functions for rAdafruitNeoPixel

I modified the AdafruitNeoPixel library in this posting: https://www.b4x.com/android/forum/threads/radafruitneopixel-based-on-neopixel-lib-v1-3-1.111313/#post-708734 Added 4 new functions: MovePixelColorDirect (To, From) - Move the pixel data from location to another directly SetPixelColorDirect3(Pixel, ULong) - Set pixel to value directly SetPixelColorDirect(Pixel, R, G, B) - Set pixel to value directly GetPixelColorDirect(Pixel) - Get the pixel value at location directly

ADXL345 Triple Axis Accelerometer Library

Sparkfun''s I2C/SPI Arduino Library for ADXL345. Using this Arduino Library, you have the option of using either SPI or I2C to communicate with the ADXL345. It is fairly reasonable to use and straight forward. You will also be able to calibrate the ADXL345 whenever necessary as shown in the example.

B4RLibraryB4R motor [S]

rTinyStepper_28BYJ_48 - A library for the 28BYJ_48 stepper motor[s]

This Arduino library is used to control one or more 28BYJ-48 stepper motors. These motors are very small with a built in gear reduction. The advantage of these motors is that they are inexpensive and easily available on Amazon. Their downside is that they''re very slow (0.3 revolutions/second max), and only suitable for light-duty applications.
