Magimix Cook Expert 18900

These are my notes in trying to understand how the Magimix Cook Expert works software / hardware wise. Would love to understand how to control the hardware, the french version has a USB bluetooth dongle that you can insert in the USB port, I want to see if I can "upgrade" my non french version to the same bluetooth connectivity.

the firmware for the non bluetooth version, and bluetooth version are identical, so in theory, its possible?

Hardware

Strings on the control unit

• BL1175_MAIN
• 2014-11-14
• V:02
• 1638
• E301544
• 94V-0
• HM-02
• IC500
• RU ( Recognized Component Mark )

The "Recognized Component Mark" is a type of quality mark issued by Underwriters Laboratories. It is placed on components which are intended to be part of a UL listed product, but which cannot bear the full UL logo themselves.[6] The general public does not ordinarily come across it, as it is borne on components which make up finished products.

Strings on IC's

IC (1) XLSEMI XL6001E1 62837 ( Identified as 400KHz 32V 2A Switching Current Boost LED Constant Current Driver )

IC (2) PIC16F82 -1/SS 327 HW

due marking, these are the options left which it can be

• PIC16F1826
• PIC16F1826T-I/SS
• PIC16F1826-I/SS
• PIC16LF1826-I/SS (I don't think its the T, since that would show on the ic)

I'm fairly certain its this one

IC (3) 6757 3S26 M-L ( does this say 3526 M-L? this could be a LM3526 Dual Port USB Power Switch and Over-Current Protection

To investigate:

What controls that giant display then? Is this something I overlooked? When I google the firmware filename lpc1788.bin, I come across NXP - LPC1788 microcontroller with LCD Graphics Controller, is this hidden under the display plate? (its on a big raiser)

Current best guess: the firmware lpc1788.bin is 220Kb, thats way too big for that PIC16F82 let alone drive a decent resolution display, images, icons, animations, etc... so I think the main chip is under the display (big aluminium box) and based on the firmware name " lpc1788" it might just be that one 🙄

LPC178x/7x web archive link

• 32-bit ARM Cortex-M3 microcontroller; up to 512 kB flash and
• 96 kB SRAM; USB Device/Host/OTG; Ethernet; LCD; EMC

This looks like something more capable then the PIC16, and it has JTAG and stuff

Software

Based on the PIC16LF1826-I/SS it looks like there are 2 compilers

• XC8 compiler
• HI-TECH PICC
