== Micro:Bit Servo Driver ==
Micro:bit Servo Driver is a motor driver from which one can control up to 16 motors simultaneously. If you're building a robot with a lot of moving parts, or if you need to monitor a lot of servo motors with PWM yields, the microcontroller's limited PWM yields will be a big problem. The most important thing you can do to solve this problem is to obtain a 16-Channel 12-Bit PWM/Servo Driver.

=== Features ===
* Adjustable frequency PWM up to about 1.6 KHz
* Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
* 3 pin connectors in groups of 4 so you can plug in 16 servos at once
* This board/chip uses an I2C 7-bit address
* Expansion Headers for easy connections
* I2C controlled and external power supply connector
* Compatible with Micro:bit and Micro:bit V2

=== Specifications ===
* External Power supply: 5V OR 6V (Via power supply connector)
* Servo voltage: 5V
* Logic voltage: 3.3V
* Driver: PCA9685
* Control interface: I2C

==== Arduino ====
* [https://github.com/moononournation/Arduino_GFX '''Arduino Library for 1.28" Round LCD Breakout''']

If you are using Arduino Ide, you can use the above library.

==== PICO RP2040 (MicroPython) ====
* Below components are required to run Pico RP2040 compatible boards :
** Raspberry Pi Pico x 1
** Pico 1.28" Round LCD Breakout x 1
** USB Cable x 1

* Copy or clone code from Github.
https://github.com/sbcshop/1.28-Round-LCD-Breakout

* Connect LCD breakout with Raspberry Pi Pico as shown in the below pinout.

<table class="wikitable">
<tr> <th>1.28" Round LCD Breakout </th> <th>PICO Pins </th></tr>
<tr> <td> VCC </td> <td> 3.3V / 5V </td></tr>
<tr> <td> GND </td> <td> GND </td></tr>
<tr> <td> LCD DIN </td> <td> GP11 </td></tr>

<tr> <td>LCD CS</td> <td> GP9 </td></tr>
<tr> <td> LCD RST </td> <td> GP12 </td></tr>
<tr> <td> LCD BL </td> <td> GP13 </td></tr>
</table>

* Press and hold '''BOOTSEL''' pin of Raspberry Pi Pico and connect the USB cable, it will create a drive as RPI-RP2.

* Now drag and drop or copy and paste '''firmware.uf2''' file from firmware folder to RPI-RP2 Drive. It will reboot your raspberry pi pico.

* Open Thonny IDE and Choose interpreter as MicroPython (Raspberry Pi Pico).
[[File:Thonny-interpreter.PNG|600px]]

* Now you can run example codes from the '''Pico_Example_mpy''' folder in Thonny Ide. For example, Open the '''hello.py''' file in thonny and click on the green play button to run this example.
[[File:Pico_Round_lcd_HAT_thonny.PNG]]

It will print "Hello" on Round LCD. You can use the joystick to change the LCD color.

==== Working Example ====
* This module was tested on Raspberry Pi Pico. You need to provide a SPI object and the pin to use for the DC pin of the screen.

<source lang="python">
import machine
import gc9a01
spi = SPI(1, baudrate=40000000, sck=Pin(10), mosi=Pin(11))

tft.init()
</source>

==== Functions and Arguments ====
* <source inline> gc9a01.GC9A01(spi, width, height, reset, dc, cs, backlight, rotation, buffer_size) </source>
required arguments:
<source>
`spi` spi device
`width` display width
`height` display height
</source>

optional args:
<source>
`reset` reset pin
`dc` dc pin
`cs` cs pin
`backlight` backlight pin
`rotation` Orientation of display.
`buffer_size` 0= buffer dynamically allocated and freed as needed.

Rotation | Orientation
-------- | --------------------
0 | 0 degrees
1 | 90 degrees

3 | 270 degrees
4 | 0 degrees mirrored
5 | 90 degrees mirrored
6 | 180 degrees mirrored
7 | 270 degrees mirrored
</source>
If buffer_size is specified it must be large enough to contain the largest bitmap, font character, and/or JPG used (Rows * Columns *2 bytes). Specifying a buffer_size reserves memory for use by the driver otherwise, memory required is allocated and free dynamically as it is needed. Dynamic allocation can cause heap fragmentation so garbage collection (GC) should be enabled.

'''This driver supports only 16bit colors in RGB565 notation.'''

* <source inline> GC9A01.on() </source>

Turn on the backlight pin if one was defined during init.

* <source inline> GC9A01.off() </source>

* Press and hold '''BOOTSEL''' pin of Raspberry Pi Pico and connect the USB cable, it will create a drive as RPI-RP2.

* Now drag and drop or copy and paste '''firmware.uf2''' file from firmware folder to RPI-RP2 Drive. It will reboot your raspberry pi pico.

* Open Thonny IDE and Choose interpreter as MicroPython (Raspberry Pi pico).
[[File:Thonny-interpreter.PNG|600px]]

* Now you can run example codes from the '''Pico_Example_mpy''' folder in Thonny Ide. For example, Open the '''hello.py''' file in thonny and click on the green play button to run this example.
[[File:114_LCD_thonny_code.PNG]]

It will print "Hello World!" on LCD.

==== Working Example ====
* This module was tested on Raspberry Pi Pico. You need to provide a SPI object and the pin to use for the DC pin of the screen.

<source lang="python">
import machine
import st7789
spi = SPI(1, baudrate=40000000, sck=Pin(10), mosi=Pin(11))
tft = st7789.ST7789(spi, 135, 240, reset=Pin(12, Pin.OUT), cs=Pin(9, Pin.OUT), dc=Pin(8, Pin.OUT), backlight=Pin(13, Pin.OUT), rotation=3)
tft.init()
</source>

==== Functions and Arguments ====
* <source inline> st7789.ST7789(spi, width, height, reset, dc, cs, backlight, rotation, buffer_size) </source>
required arguments:
<source>
`spi` spi device
`width` display width
`height` display height
</source>

optional args:
<source>
`reset` reset pin
`dc` dc pin
`cs` cs pin
`backlight` backlight pin
`rotation` 0-0 degrees, 1-90 degrees, 2-180 degrees, 3-270 degrees
`buffer_size` 0= buffer dynamically allocated and freed as needed.
</source>

If buffer_size is specified then it must be large enough to contain the largest bitmap, font character, and/or JPG used (Rows * Columns *2 bytes). Specifying a buffer_size reserves memory for use by the driver or else memory required for the data will be allocated dynamically as per the data size. Dynamic allocation can cause heap fragmentation so garbage collection (GC) should be enabled.

'''This driver supports only 16bit colors in RGB565 notation.'''

* <source inline> ST7789.on() </source>

Turn on the backlight pin if one was defined during init.

* <source inline> ST7789.off() </source>

Turn off the backlight pin if one was defined during init.

* <source inline> ST7789.pixel(x, y, color) </source>

Set the specified pixel to the given color.

* <source inline> ST7789.line(x0, y0, x1, y1, color) </source>

Draws a single line with the provided color from (x0, y0) to (x1, y1).

* <source inline> ST7789.hline(x, y, length, color) </source>

Draws a single horizontal line with the provided color and length in pixels. Along with vline, this is a fast version with reduced number of SPI calls.

* <source inline> ST7789.vline(x, y, length, color) </source>

Draws a single horizontal line with the provided color and length in pixels.

* <source inline> ST7789.rect(x, y, width, height, color) </source>

Draws a rectangle from (x, y) with corresponding dimensions

* <source inline> ST7789.fill_rect(x, y, width, height, color) </source>

Fill a rectangle starting from (x, y) coordinates
