FUJITSU MBF200 fingerprint sensor - Help!(initialization)

how to set up fujitsu fingerprint sensor

Hi!

I am working on a project using the MBF200 fingerprint sensor,I can write and read sensor's registers in SPI mode exactly.For example,when the "CIDH" is read,we can get "0x20",when the "CTRLC" is write as 0x01,the pin p0 goes high.The problem is that when I put my finger onto the sonsor,there is no interrup generated.The code of initialization is shown as follows:

void MBF200_init(void)
{
set_sensor_register(F_CTRLA,0x00);
set_sensor_register(F_THR,0x48); //Setup threshold values
set_sensor_register(F_CTRLB,FSENSOR_ENABLE | F_AUTOINCEN | F_AFDEN);

Delay(40); //delay 40us
//Adjust Parameters
set_sensor_register(F_DTR,0x40); //Setup discharge time
set_sensor_register(F_DCR,0x10); //Setup discharge current
set_sensor_register(F_PGC,0x08); //Setup gain

set_sensor_register(F_ISR,0x03); //clr any pending
set_sensor_register(F_ICR,0x11); //Finger Detect Interrupt Polarity is Falling Edge or Active Low,Finger Detect Interrupt is Edge Triggered,Finger Detect Interrupt is Level riggered,Finger Detect Interrupt Enabled

Delay(100);
}

I don't know how to ajust the parameters,who can tell me?

Now the fp pic read almost the same.

i think the ADC does not work.....................

boss:"How about the project?"

me:"oh....i....i think maybe ....maybe.....tomorrow..."

boss:"tomorrow!!!!!!##$#$$#%$%^^&%^&%&^&%"

me:"help!!!!!!!!!"

fujitsu fingerprint does not accept



Added after 7 minutes:

//Adjust Parameters
set_sensor_register(F_DTR,0x40); //Setup discharge time
set_sensor_register(F_DCR,0x10); //Setup discharge current
set_sensor_register(F_PGC,0x08); //Setup gain

Where did you get this parameters from? I was trying with the data for this registers that FUJITSU sent to me but a have no success.

I don't know how to ajust the parameters,so I setup the registers with the middle value.How about your project now?

fujitsu fingerprint sensor tutorial

Can u please post your initialization code? What values did u for DTR and DCR etc in your finalised code?

Also how can you tell that the sensor has been initialized correctly ?

how to setup fujitsu fingerprint sensor

hi

i just wanted to know what are the prices for this sensor and is there any development kits for it? if yes how much to pay in such kit.

thanks
