hi, i am developing a weigh scale application using Cirrus Logic 5532 24-bit ADC in unipolar mode.the output i am getting is very unstable (flickering on display). Can anybody please tell me how to get a stable count.
First of all i would like to tell u that the problem was with power line noise rejection. I had wrongly configured the ADC for 60Hz noise rejection(7.5Sps OWR) instead of 50Hz noise rejection and corresponding OWR of 6.25Sps.The display is now much stable(+-1 weight). this is my first project ... Get an analog PCB layout book or you will never get anywhere with this. This really is my first project. i am only developing the software for the project invloving the interfacing of the uc with the ADC, display, keyboard and AT24C02 eeprom in C using keil C51 tools and hence wanted to how if any coding could control the flickering. i was not part of the pcb desinging and layout process.
First of all i would like to tell u Why do you use the forum to tell micro something? now: The display is now much stable(+-1 weight). earlier: my display is flickering in +/- 7 counts range with occasional surges do you still have the "occasional surges"? Erik
