hello bajrang, i took this code and changed to what suits me... the next step is actually interfacing with the device. i was wondering if you can help me out and share anything you have wrote which comes after the enumeration. i am mostly interested in the "get the report from the device process".
thanks in advance.

I run an open source development project based on max3421e aimed primarily at small 8-bit MCUs, like PIC18s and AVR (Arduino platform). The code is written in C. It is hosted here -> http://www.circuitsathome.com/category/mcu/usb
Let me know if you have any questions.
Oleg.

Hi,
i'm using this source code.
I can write correctly, but i can't read!!
i know i can write because with Hwreg() i can modify the state of the GPOUT pins of the max controller, but NO READINGS.
The only modify i did is the init of the SSP,
with these vals:
SSPCR0 = 0x3B07;
SSPCPSR = 0x02;
SSPCR1 = SSPCR1_LBM | 0x02;
(but with original vals it didn't work too)
i'm using the P1.20 as chip select, instead of P0.20.
then i do the following function after issuing HRES_LO and HRES_HI:
void func(){
BYTE result;
Hwreg(rPINCTL,(bmFDUPSPI | bmINTLEVEL));
while(1){
result = Hrreg(rRevision); //try to read revision reg
PrintOut("READ: %x
",result);
}
}
the only thing i got is:
READ: 0
if i add another istruction: dum = SSPDR;
before the return of the Hrreg() (just after the while)
i have:
READ: 0
READ: 8a
READ: 90
READ: 90 -> (forever)
and this is what i just wrote to the SSP ! it gives me no content of the regs i want to read, because this happens for any register i try to read.
Please i need help from the support of the maxim or by any other one.
Thank you

- Control write with data stage

Hi,
Maxim has written "BYTE CTL_Write_ND(BYTE *pSUD);" in their demo program for MAX3421E.
Has anyone tried to write "control write with data stage"?
Or another way, has anyone tried to set the status leds on the keyboard?
Thanks.
