## **3.2 Power supply** 

There are 2 options for powering the IDM2040-43A module: 

- 5V/0.5A USB Type-C connector - CN3. 

- Or 5V/0.5A 1x6 position 2.54mm Harwin male header CN4/CN5. 

Both power inputs are summed using Schottky diodes so the source with higher voltage will be use to power the system and back flow current will be blocked.  Power will then go to the DCDC Buck switching regulator to output the 3.3V supply for powering up the system. 

## **3.3 Microcontroller- Raspberry Pi RP2040** 

The Raspberry Pi RP2040 microcontroller unit used in the module has the following key features: 

- Dual ARM Cortex-M0+ @ 133MHz 

- 264kB on-chip SRAM in six independent banks 

- Support 8MB of on-board Flash memory via dedicated QSPI bus 

- Type-C USB port supporting USB2.0 Full-speed device function; reprogramming the Flash can be achieved by simply dragging and dropping a file onto the RP2040 which appears as a mass storage device. 

- 26 multi-function 3.3V General Purpose I/O (GPIO) with 23 GPIOs being digital-only and 3 ADC-capable GPIOs. 

- 3-pin ARM Serial Wire Debug (SWD) port; the standard Serial Wire Debug (SWD) port can reset the system and load and run code without any button presses as well as for debugging purpose. 

For full details of the Raspberry Pi RP2040 MCU, please refer to the RP2040 Datasheet.

**Note 1:** The parameter is slightly changed by temperature, driving voltage and material 

**Note 2:** The data are measured after LEDs are turned on for 15 minutes. LCM displays full white. The brightness is the average value of 9 measured spots. Measurement equipment BM ~~7~~ (@ 5mm) 

Measuring condition: 

- Measuring surroundings: Dark room. 

- Measuring temperature: Ta=25 °C . 

- Adjust operating voltage to get optimum contrast at the center of the display.

## «RY,* BridgetekBRIDGINGa TECHNOLOGY 

## **7 Software Setup Information** 

- The RP2040 microcontroller can be programmed using C/C++, MicroPython or CircuitPython. 

## **7.1 C/C++ SDK Setup** 

- For C/C++ development, the following programs need to be installed. 

Python 3.x ARM GCC compiler CMake Build Tools for Visual Studio 2019 (C++ build tools only) Visual Studio Code pico-sdk tools 

- It is recommended to download one package of all the above tools from here to install them. 

- Raspberry Pi PICO/RP2040 C/C++ SDK document can be downloaded here. 

- Raspberry Pi PICO/RP2040 C/C++ examples can be downloaded here. 

- Raspberry Pi PICO/RP2040 C/C++ API Document is here. 

- Download and install latest EVE Screen Designer (ESD) from here. 

- Open ESD tools and run any example provided in the application. 

- User needs to change the build target to IDM2040-43A via the toolbar button. User needs to build code to generate UF2 file. 

- Push and hold SW1 BOOTSEL button on board while powering up the module by connecting CN3 to the computer using USB type C cable. Release BOOTSEL once the drive RPI-RP2 appears, drag and drop the UF2 file into the RPI-RP2 drive. 

## **7.2 MicroPython SDK Setup** 

- Download the MicroPython UF2 file from MicroPython. 

- Push and hold SW1 BOOTSEL button on the board, then connect your computer using a type C USB cable. Release BOOTSEL once the drive RPI-RP2 appears on your computer 

- Drag and drop the UF2 file into the RPI-RP2 drive. The RP2040 will reboot and will now run MicroPython. 

- Download and install Thonny for your computer. 

- Connect the board to your computer and in Thonny go to Tools>Options and click on the interpreter tab. From the interpreter dropdown list select MicroPython (Raspberry Pi PICO). Choose port "USB Serial Device (COMX)” . Figure 20 shows the Micropython with Thonny in ready status.

- Raspberry Pi PICO/RP2040 MicroPython SDK document can be downloaded from ~~—__~~ here. 

- Raspberry Pi PICO MicroPython examples can be downloaded from ~~——~~ here. 

- Blink D2A example code is 

_from machine import Pin import utime led = Pin(25,Pin.OUT) while True: led.value(1) utime.sleep(1) led.value(0) utime.sleep(1)_ 

## **7.3 Circuitpython SDK Setup** 

- Download the CircuitPython UF2 file from ~~a~~ CircuitPython. 

- Push and hold SW1 BOOTSEL button on the board, then connect your computer using a type C USB cable. Release BootSEL once the drive RPI-RP2 appears on the computer. 

- Drag and drop the UF2 file into the RPI-RP2 drive. The RP2040 will reboot and the drive CIRCUITPY will appear. 

- Download and install —_____ Thonny  or — Mu for your computer, recommend to install Mu editor for CircuitPython application. 

- Connect the board to your computer and Run Mu, select RP2040, the MU with CircuitPython is ready to use.
