4. Flashing CPU

CPU can be flashed using one of following methods:

UART flashing method

This is the slowest method, if possible consider using USB method

Needed tools and software:

• USB A-B cable
• PC with Windows
• STM32CubeProgrammer software installed can be downloaded here: STM32CubeProgrammer software for all STM32

Procedure:

1. Set J1 jumpers to as shown below:

2. Connect USB A-B cable to maximite and PC
3. Open STM32CubeProgrammer program

4. Select UART
5. Select COM port
6. Press and hold FLASH button and press RESET button while still holding FLASH
7. Press connect, successful connection will be reported in Log

8. Go to Erasing & Programming tab

9. Browse and select firmware
10. Press Start Programming button, flashing will start:

11. Successful flashing will be reported by po-up window and Log:

12. Press disconnect button
13. Reboot the unit by using power switch or RESET switch

USB flashing method

This method is much faster than UART method, requires USB A-A cable

Needed tools and software:

• USB A-A cable
• PC with Windows
• STM32CubeProgrammer software installed can be downloaded here: STM32CubeProgrammer software for all STM32

Procedure:

1. Connect USB A-A cable to maximite keyboard port and PC
2. Open STM32CubeProgrammer program
3. Press and hold FLASH button and press RESET button while still holding FLASH, You should hear Windows found device sound

4. Press refresh icon and select USB1 (or other) from drop down menu
5. Remaining steps are identical as those described in UART flashing method starting from step 7

5. Expansion system

Maximite Deluxe 2 GEN2 is equipped with 5 edge connectors used with expansion cards. IDC40 (J9) and IDC26 (J13) are used to daisy chain expansion modules: Expansion Module

Expansion cards can be used only when top cover is removed or modified (slots are cut in enclosure)

Powering Maximite from expansion Power Card

If You need to power Maximite system from Power card please remove solder jumpers JP1 and JP6 marked below to disconnect internal power sources. 12V DC 2,5/5,5mm connector is used to supply Power Cards.

Expansion cards

Following expansion cards are available or are in development:

ID	Name	Desc.	Status
01	Mouse/joystick card	adds: USB mouse (HT chip) including wireless, Atari joystick, Nunchuk port	done
02	Relay card	Relay card controlled by shift registers, can be daisy chained, only 3 pins needed to operate multiple cards	in progress
03	Power card	delivers high amperage 5V and 3.3V to be used with power hungry cards	done
04	Prototyping card	simple prototyping card	done
05	WiFi card	adds wifi functionality, includes USB to RS chip allowing easy flashing and communication with pc	done
06	Shift register card	helps to learn how shift registers work, 16 led operated from 3 pins, can be daisy chained	done
07	rs232 card	adds 2 standard RS232 ports	in progress

6. WiFi ESP01

This card adds wifi functionality, includes USB to RS chip allowing easy flashing and communication with pc

ESP01 setup

use jumper J1 to configure COM port that CPU is using to communicate with ESP module as shown above

ESP01 flashing

1. Use jumper J1 to connect Maximiate USB to UART chip with ESP module ash shown above

2. Connect USB A-B cable to PC and Maximite
3. Power on Maximite
4. Find out which COM port is detected by PC
5. Select COM port in Your flashing tool
6. Start flash

7. Hold PROG. button and press RESET button while still holding PROG. button
8. Wait until flash completes

7. UBS mouse host chip

Device is equipped with HT mouse host chip that allows to connect many devices available on the market. Mouse is connected to bottom USB port.

  local integer x=mouse(x,2),y=mouse(y,2)
  gui cursor off
  gui cursor on 1,x,y,rgb(red)
  n=n+1
  print @(100,100)"left",n
  end sub
'
sub rightclick
  static integer n=0
  local integer x=mouse(x,2),y=mouse(y,2)
  gui cursor off
  gui cursor on 0,x,y
  n=n+1
  print @(200,100)"Right",n
end sub

flashing

Below You can find procedure for flashing mouse host chip:

1. Download frirmware and ds30 Loader from this page: HobbyTronics

2. Set J1 jumpers as shown above
3. Make sure that no device is connected to MOUSE port of Maximite
4. Connect maximite to PC with USB A-B cable and power the device
5. Find out COM port detected by PC
6. Select proper COM port
7. Browse for hex file

6. Select device, and baud rate as shown above
7. Press write

8. Press RESET (SW6) button near HT mouse chip

8. Nunchuk

9. Atari joystick

In table below You can find pinout for Atari Joystick DB9 socket:

DB9 pin	Function	Maximite IDC40 pin
1	UP	35
2	DOWN	36
3	LEFT	38
4	RIGHT	40
5	nc	nc
6	BUTTON A	32

Code example can be found below:

SETPIN 35, DIN, PULLUP
SETPIN 36, DIN, PULLUP
SETPIN 38, DIN, PULLUP
SETPIN 40, DIN, PULLUP
SETPIN 32, DIN, PULLUP

DO
  IF PIN(35) = 0 THEN PRINT"UP"
  IF PIN(36) = 0 THEN PRINT"DOWN"
  IF PIN(38) = 0 THEN PRINT"LEFT"
  IF PIN(40) = 0 THEN PRINT"RIGT"
  IF PIN(32) = 0 THEN PRINT"FIRE"
  PAUSE 100
LOOP

10. IR sensor

Device is equipped with IR sensor, only standard RC remotes will work with libraries included in MMBasic

Example code can be found below:

IR dev, KeyCode, IR_Int
Do

LOOP

SUB IR_Int
  PRINT "Received device = " DevCode "  key = " KeyCode
END SUB

11. RTC

Device can be equipped with RTC chip (this chip has to be soldered by user on U23 pad). Out of the box Maximite is using CPU RTC, to change to external RTC use following code:

OPTION DS3231 ON

after enabling external RTC remember to set the date:

DATE$ = "DD-MM-YY"

To turn off external RTC use code below

OPTION DS3231 OFF

12. MM edit

Build in code editor is not the only way code can be edited and tested. You can find MM edit more effective way to write and test programs on Maximite.

You can download it here: MM Edit2

To use MM Edit with Maximite:

1. Set J1 jumpers as shown above
2. Connect maximite to PC with USB A-B cable and power the device
3. Find out COM port detected by PC

4. Open MM Edit program

5. From drop down menu select: Connect >> New...

6. Select serial port and speed (default: 115200)

7. Press Save configure

8. From drop down menu select: Connect and select newly created configure 9 From drop down menu select: Connect >> Connect to Maximite

After creating new code You can send it and automatically run in maximite by selecting from drop down menu: Connect >> Load and Run
