Hi all,
We are working on a project where a PIC is talking to a Philips TDA8822
modulator via I2C for configuration of the device. The problem we are having
is that the RF oscillator will not start. I believe we have all the registers
set properly to keep it from being disabled, etc. but no luck. Does anyone
have any experience in this area, or better yet with this chip, that could
give us some things to check. We are dead in the water with this project until
we can get the modulator's oscillator to start. We have verified the I2C
connection by using it to toggle a general purpose i/o pin on the device. Any
help is appreciated. Thanks.
