아두이노 퓨즈비트 설정관련

기본값으로 설치되었다는 전제하에

아래 경로에 플래시 구울때 사용하는 설정들이 존재한다.


아두이노는 기본적으로 USB 파워나 외부 전원을 통해(7805) 5V를 공급하도록 되어있는데

7805를 들어내거나 결선을 바꾸거나 외부 Vcc에다가 3.3V를 넣어 주고

클럭을 다운시켜 작동하면 좀 간편할지도?


아니면 프로미니 3.3V 이런거라던가?


ATmega328 running at 8MHz with external resonator (0.5% tolerance)

Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, accelerometers, sensors, etc)

아두이노 외부 프로그래머로 굽기

툴에서 설정을 해놨다면 그걸 이용해서

스케치 - 프로그래머를 이용해 업로드

를 함으로서 stk500 호환 usbisp 등을 이용해 업로드가 가능해진다.

아두이노 부트로더 굽기?



 

예전에 가지고 있던 녀석으로 구워볼려고 했더니..

프로그래머 이녀석은... 굽는 용도가 아닌가? 안되지 왜?

(어쩌면 보드를 정해줘서 그런걸지도..)


아무튼 STK500 개발보드로 하니 USBISP로 구워진다

라즈베리는.. i2c slave 모드 불가?

안된다는 말이 있어서 따라가보니...

핀 자체가 실장이 안되어 있다고... (GPIO19)



bcm2835 has support for I2C slave. Refer to section 11 of http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf


Unfortunately, GPIO pin 19 (BSC slave CLK) was dropped. http://elinux.org/RPi_BCM2835_GPIOs


So, the built-in I2C slave cannot be used.

[링크 : http://playground.arduino.cc/Main/I2CBi-directionalLevelShifter]

2016/04/01 - [embeded/arduino(genuino)] - 아두이노 level shift / MPU-6050


The Raspberry Pi is running at 3.3 Volts while the Arduino is running at 5 Volts. There are tutorials suggest using a level converter for the I2C communication. This is NOT needed if the Raspberry Pi is running as “master” and the Arduino is running as “slave”.


The reason it works is because the Arduino does not have any pull-ups resistors installed, but the P1 header on the Raspberry Pi has 1k8 ohms resistors to the 3.3 volts power rail. Data is transmitted by pulling the lines to 0v, for a “high” logic signal. For “low” logic signal, it’s pulled up to the supply rail voltage level. Because there is no pull-up resistors in the Arduino and because 3.3 volts is within the “low” logic level range for the Arduino everything works as it should.

걍.. 과감하게(?) atmega 녀석들이 대부분 2.8V~5.5V 니까 3.3V로 주면 안되려나?


Operating Voltage:

1.8 - 5.5V


TWI(I2C)쪽 입력 전압은 Vcc + 0.5 니까.. 3.3V 주면은.. 어떻게 안되려나?

그나저나.. 0.3V~0.7V 로 무지 좁네..

가속도계로 각도계산하기

어... 단순하게 arctan으로 하면 땡~이 아니었던게야?!?!?!





void calc_xy_angles(void){

   // Using x y and z from accelerometer, calculate x and y angles

   float x_val, y_val, z_val, result;

   unsigned short long x2, y2, z2; //24 bit


   // Lets get the deviations from our baseline

   x_val = (float)accel_value_x-(float)accel_center_x;

   y_val = (float)accel_value_y-(float)accel_center_y;

   z_val = (float)accel_value_z-(float)accel_center_z;


   // Work out the squares 

   x2 = (unsigned short long)(x_val*x_val);

   y2 = (unsigned short long)(y_val*y_val);

   z2 = (unsigned short long)(z_val*z_val);


   //X Axis

   result=sqrt(y2+z2);

   result=x_val/result;

   accel_angle_x = atan(result);


   //Y Axis

   result=sqrt(x2+z2);

   result=y_val/result;

   accel_angle_y = atan(result);

}

OV5647 라즈베리 카메라 관련

음.. FREX 핀은있으나.. 웬지 라즈베리용 카메라에는 FREX를 빼놓지 않았을 기분?



43p

[링크 : http://www.ovt.com/uploads/parts/OV5647.pdf]


어? 120p가 안돼?

Frame rate up to 120 fps

max 90fps. Limitations on frame size for the higher frame rates (VGA only for above 47fps)


그리고.. external / internal sync. 미지원

Support for internal and external frame synchronisation for frame exposure mode

No

라즈베리 파이 CSI multiplexer

한마디로 4채널까진 해상도 좀 낮춰서 1Gbps 보다 낮게 설정하면(동시 4채널까진 가능하단건가?)

OV5647 can be synched with another sensor using the FREX pin input/output (works also in rolling shutter mode). Needs support in driver though. Guess the FREX pin is not even used in Raspberry Pi Camera design, at least Omnivision reference desing tells not to populate the zero ohm resistor which connect this pin to connector.

The Raspberry Pi has a Mobile Industry Processor Interface (MIPI) Camera Serial Interface Type 2 (CSI-2)

MIPI CSI-2 version 1.01 supports up to four data lanes, where each lane has a maximum of 1 Gbps bandwidth, to provide a total bandwidth of 4 Gbps.

음? 카메라 모듈이 기본 2개니까.. 2채널은 동시?


MIPI interface (two lanes) Yes

그게 명칭인줄 알았더니.. genlock이 명칭인가?
