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,I 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 interrupt 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?

Thx

Did you get the sensor to work? were you able to recieve data on to the controller flash. Can you tellme how you did it?

did you connect any oscillator to it?

We were able to get the values of the register once written into them, but we are unable to read from theA/D. Can you help us out here?
 

can any one please tell me where to get MBF200. i want it to solder it on PCB and use it in my project. so are there any distributors available.??
