hi
we have a project with module sim20.
We want to develop 400 networks with sim20 module that every network has about three nodes in 1km squar environment , is it possible and if we do that will we have any problem?
hi
i want to use gyro , accelermeter and magnetometer to get a full smooth rotation in 3 axis.
the first problem is that my outputs individualy has very noise and i want to know how can i remove it.
the second problem is the gyro drift that i think it should solve with kalman filter.
the...
i want write a program to first read adc and then read i2c data and reapet this but the pin of adc and i2c is same how should i create circuit and write program for this purpos?
hi
i want to write a program in codevision to work avr with hmc5843 but i cant read from sensor
after send SLA +R the value of TWSR become 0x40 that means byte has sent and ack reseved but nothing placed in TWDR what is the problem?
TWDR=0x3D; // slave address for read
TWCR=0x84; // Enable TWI...
hi
i want to send informations via serial port
this is my proram in winccr
i want to send 0 to 255. but this program send 0 to 14
and another problem is speed of sending .
this program with _delay_ms(1) send 800 chars in one second and without it nothing will send i thing speed should be more...
mega16l usart vcc=3.3v
recomended voltag is 5v but it work with lower powers
i think that problem is from output of micro
when i use 5v out put is about 5 and circiut work well but when i use 3.3v output is abut 2v and max232 cannot get it
mega16l usart vcc=3.3v
hi
i want to create a circuit that have an atmega16l to send some information via usart using max232.
my circuit work when i use 5v as supply power but not when i use 3.3v
i use 6 mh ocilator
what should i do. is there a specific work should be don with lower voltage than...
hi
i have a adxrs300 gyro that have an analog output.when i connect the output to a a/d(analog to digital) pin of a avr micro the data isnt correct
is it possible to connect sensor directly to avr?
euler matrix
hi
i have three gyro adxrs300
each gyro can give us rotation about itself
this is a gyro
**broken link removed**
the gyros place vertically about together
like this
**broken link removed**
how can i convert angles from gyros to a euler matrrix rotation?
