[Micropython] Tpyboard v10x interpolation programming experiment lighting heart-shaped dot matrix

First, what is the Tpyboard Development Board

Tpyboard is a Micropython development Board made by Turnipsmart company based on Micropython licensed by MIT, which transmits data via USB interface on the basis of stm32f405 MCU. The board contains 4 LEDs, an acceleration sensor, which can operate at voltages between the 3v-10v. The Tpyboard Development Board allows users to easily control various peripherals of the microcontroller via Python code, such as LEDs, reading pin voltages, playing songs, networking with other devices, and more. The Tpyboard Development Board supports direct operation of Python3.0 and above, supports acceleration accelerometer, supports peripheral peripherals, and supports SWD to burn and write firmware. 0 Basic can also be flexibly mastered single-chip microcomputer technology!

Second, the use of Tpyboard point to light the heart-shaped lattice

1. Specific requirements

The display of heart pattern is realized by connecting the red 8x8led lattice screen with the tpyboardv10x Development Board.

3, 8x8 lattice screen introduction

There are two rows of pins behind the lattice, a row with 1, that is, 1-8 pins, a row with 9 (8 pins are the opposite of the pin), that is, 9-16 pins, the number within the circle is the corresponding serial number of the PIN. The corresponding PIN for ROW 1 is 9. When a row's pin is high, and a Col's pin is low, the LEDs of their intersection are lit. To facilitate the operation of rows and columns, we can connect the row's 8 pins to our Tpyboard v102 X1-x8,col's 8 pins to our Tpyboard v102 y1-y8. This allows us to control the brightness and not light of each led by controlling the high and low levels of the X-pin and y-pins, so that you can design any characters and graphics you want to display, so try it.
