This board features innovations that set it apart from other 7-segment module. Innovations feature like on-board I2C address jumpers, pull-up resistors, power LED and 2.5V reference. The module can be quickly connected directly on to the breadboard. The board is small and compact in size 1.50 x 2.05 inches. The I2C-7SEG is designed base on SAA1064 IC. The circuit is especially designed to drive four 7-segment LED displays with decimal point by means of multiplexing between two pairs of digits. It features an I2C bus slave transceiver interface with the possibility to program four different SLAVE ADDRESSES, a POWER RESET flag, 16 current sink OUTPUTS, controllable by software up to 21 mA, two multiplex drive outputs for common anode segments, an on-chip multiplex oscillator, control bits to select static, dynamic and blank mode, and one bit for segment test. A jumper pins vary the fixed I2C address and allow up to four devices to share the same I2C bus. Address selection input (DO NOT connect this pin when using internal address mode) Five colors to choose from (green, red, orange, orange/red and yellow) Flicker free multiplexed 7-segment display Total control of individual segment Display brightness controllable by software Automatically refreshes and updates each display digit Free up host controller for continuous display updates and refresh loops On-board I2C address jumpers, pull-up resistors and power LED Small and compact in size 1.50 x 2.05 inches Single row 0.4 width, 0.1 pitch header pins Flexible operating power supply voltage range of 4.5V to 15V Suitable for 5.0V microcontroller For more information please see: I2C-7SEG User Manual Basic Stamp BS2P example code: I2C-7SEG.bsp PICAXE example code: I2C-7SEG-PICAXE.bas Arduino example code: I2C-7SEG-Arduino.pde SAA1064 datasheet: SAA1064.pdf (I2C-7SEG (I2C 4-dig 7-segment) basic stamp, pic, atmel was posted and is owned by: Billie Oneill) |
