bouni / matedealer Goto Github PK

Hello,

I'm testing mdb to arduino interaction and want to use your code.

First of all, I ran

sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude

Secondly, I ran

cd MateDealer && make all

What should I doing next?

Can give me the details and schematic of hardware for MDB.
Thank you.

Hello, thank you for make it code and your blog very good !

I have problem. i read your blog at http://blog.bouni.de/2012/the-mdb-protocol-part-3.html, the setup command (111H) will has 2 sub command : 000H and 0001H

I have VMC board. and i try send 100H (ACK) when Reset command and then send 000H 100H when PULL command and then VMC send it

+V: 0x111
+V: 0x010
+V: 0x111
+V: 0x010
+V: 0x117
+V: 0x117

Are you know about sub command 010H in SETUP command ?

Thanks !

This my code (Arduino) without UART file

extern void MDB_write(int data) ;
extern int MDB_read() ;
extern int MDB_available() ;
extern void MDB_setup() ;

void setup() {
  MDB_setup();

  Serial.begin(9600);
  Serial.println("Start !");

}

#define WAIT_DATA_1_Byte() { while (!(UCSR1A & (1 << RXC0))); }
#define READ_DATA_1_Byte() (((UCSR1B & 0x2) << 7) | UDR1)

int isReset = true;

void loop() {
  WAIT_DATA_1_Byte();
  int b = READ_DATA_1_Byte();
  if (b == 0x110) {
    WAIT_DATA_1_Byte();

    if (READ_DATA_1_Byte() == 0x010) {
      MDB_write(0x100);
      isReset = true;
      //Serial.println("Respont RESET command");
    }
  } else if (b == 0x112) {
    WAIT_DATA_1_Byte();

    if (READ_DATA_1_Byte() == 0x012) {
      if (isReset) {
        MDB_write(0x000);
        MDB_write(0x100);
        //Serial.println("Send Just reset");
        isReset = false;
      } else {
        MDB_write(0x100);
        //Serial.println("Send ACK");
      }
    }
  } else if ((b&0xF8) == 0x10) {
    Serial.print("+V: 0x");
    Serial.print(b >> 8, HEX);
    if ((b & 0xFF) < 0x10) Serial.print("0");
    Serial.print(b & 0xFF, HEX);
    Serial.println();
  }
}

I am currently trying to couple a Nespresso dispenser with your MateDealer system.

I have the first part of the process established, with the RESET, the POLL of the machine, the SETUP stage 1, the SETUP stage 2. Then the machine waits a few seconds and sends the RESET command and starts the cycle again.

Has anyone ever tried to configure one of these distributors? Could you help me find what's wrong with the system.

thank you so much

I'm trying to make the web interface work but I can't figure out which versions of Flask, Flask-SqlAlchemy etc. should I use. Are there any requirements.txt or description of module versions?

The license file describes an MIT-like license but most .h/.c files refer to GPL.
(Last commit removes some other GPL declarations)
Thank you!

First of all, great project and very well documented on your blog. Thanks alot!

About the issue:
When the VMC sends Vend-Session complete (113h 004h 017h) the mate dealer should answer with end session (N07h) and not with ACK (100h). I don't know if 'N' should be logic 1 or 0.

It's only small detail, maybe they changed the speccs in the meantime....?

If you accept the issue, please also update it on your blog for consistency or make a remark.
