Hi,
I use an ADXL335 accelerometer with ATMEGA328P in my project and i have problems when i read values from the 3 axis. The values are always the same and the value are 1023. I use a LP2950ACZ-3.0 for regulate the voltage to ADXL335 VCC. In the LP2950ACZ-3.0 output i use a 2.2 uF capacitor. If I use the arduino plataform (same micro controller) i haven't this problem. Can you help, please?
I already make some changes... I used a LM3940 regulator (regulate voltage to 3.3v) but i haved the same problem.
Help me!
Thanks in advance.
