Teensy 3.6, So the deal is I'm using a DAC where the data format should like like this (below), This is just from polling the the spi bus the old fashioned way. Meaning I need to do... Set CS low 3bytes DMA transaction Interrupt Set CS high GOTO step 1 Is there a "simple" way to do this...

Hey guys, thanks for all your help. The problem ended up being something really simple... The breakout board I bought has a pin called "VIO" which essentially sets the logic level for the chip. I was leaving it floating... Everything works fine now, I should probably examine all the pins of the...

Yes I was Not from what I can tell... Its still just sitting up at 3.3V

Both signals are hanging around 3.3V I checked with a voltmeter to make sure I was triggering properly, its 3.3vdc

Resistance: SCL -> GND = 201k SDA -> GND = 201k SCL -> SDA = 4.82k SDA -> +3.3 = 2.5k SCL ->+3.3 = 2.5k Continuity from +3.3 rail to pin on slave. Continuity from GND rail to pin on slave. I have a scope, I'll take a look at it in a bit.

I tried using the standard library as well as reducing the speed to 100khz. No go. Your code yields this result: Here are some pictures of the cct. just in case I got it wrong... personally I don't see what I could have done wrong but anything's possible. (There are two 10k resistors in...

#include <i2c_t3.h> volatile byte action; volatile byte AxL, AxH, AyL, AyH, AzL, AzH; volatile byte GxL, GxH, GyL, GyH, GzL, GzH; void setup() { int error; Serial.begin(9600); Wire.begin(I2C_MASTER, 0x00, I2C_PINS_18_19, I2C_PULLUP_EXT, I2C_RATE_400)...

Hey guys, to test the IMU I downloaded freeIMU from this thread: http://forum.pjrc.com/threads/23946-Teensy-3-0-Free-IMU from what I can tell it should be compatible already, but when I check the serial monitor the data isn't changing. I feel like I might be missing something key. edit...

Yup, thanks for your reply

Thanks so much, but no dice still. Its compiles fine but I get no output on the serial monitor.

I'm having troubles interfacing my Teensy 3.0 w/ a MPU 6050. From my research, it seemed like a pretty simple task but I'm having troubles getting the devices to even communicate properly. This is the breakout board I'm using: https://www.sparkfun.com/products/11028 I'm using pins 18,19 on the...
