MIKROE-2246

Matrix click From MikroElektonika Documentation Matrix click is a mikroBUS™ add-on board with two red or green (there are two options) 5x7 matrices driven by two MAX7219 8-bit LED Display Drivers. The active area of each matrix is 7.62mm high and 5.08 mm wide. 7x5 is a standard resolution for displaying ASCII characters, so 7x10 click is essentially a dualcharacter display capable of showing letters in more readable typefaces compared to a 14-segment display. The click communicates with the target MCU through the mikroBUS™ SPI interface with two separate Chip Select lines for each matrix (CSL for the left, CSR for the right). This board is designed to use a 5V power supply. TK click Features and usage notes The 7x5 LED matrix is a standard resolution for displaying ASCII characters. Matrix click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. Schematic also available in PDF (http://cdndocs.mikroe.com/images/f/f4/Matrix_G_click_schem If you double up on a board with two adjacent mikroBUS sockets, such as clicker 2 or Flip & click, you will get four characters. The possibility to horizontally scroll the text makes for a virtually unlimited space for displaying written information. Programming The code snippet results in blinking two by two letters of string provided as a first parameter.
