Hi guys,
So I am trying to get measurements from the MPU-9150 sensor from Invensense using the Intel Edison. I am able to communicate with the sensor and the values seem sensible.
But after a specific number of cycles, I measure only a zero from all data registers. This error is repeatable...
The LED is just another diode. The voltage and current are exponentially related. That means even a small change in voltage might cause a drastic change in current. So you must limit the current flowing through it using an appropriate resistor. For more info refer the following link. Light...
:!:Whenever you use the internal flash-ROM of 8051, connect the EA(pin 31) to VCC. If at all you need an external ROM you have to ground it since it is active 'low'.
So, in the hardware connect pin 31 to VCC.
P.S. Proteus does not take that into account, so you got the result in simulation
Check whether you have connected the data pins of the LCD in order. i.e. D0 to P1_0; D1 to P1_1 etc. Maybe you got every connection ok. Then check the microcontroller by writing a simple test program.
That's pretty simple. Look for ADLAR bit in the ADMUX register. When it is written a '0', 10-bit resolution is selected and the lower 8-bits are stored in the ADCL register and the remaining two bits are stored in the ADCH reg. When you write a '1' to the ADLAR bit, 8-bit resolution is selected...
Hi,
I have 2 bytes of data to transmit serially. At the receiver, i want to compare the bytes. Do i need to use a array to buffer the serial data? Or is there any other way it can be done?8-)
I am using a three-dimensional accelerometer. I am planning to use x and y axis for my project. I have connected the two axis to the ADC of my atmega32. So, i'll be getting two 8-bit values of ADC. I want to transmit them through zigbee. How will i know which axis has been received at the other...
Hi,
You can use TSOP1738 IR receivers. They are easily available and are commonly used in TV remote control receivers. But they are excited only by an IR radiation of frequency 38kHz. So, you also need a 38Khz astable oscillator using 555 timer.Refer the following circuit for emitter. For that...
