A few months ago I managed to implement the sine test on a VS1011e interfaced to a Pic18lf4550 in a circuit I have put together on a bread board. However, comming back to this project since then, I am unable to get the VS1011e function.
In reading the VS10XX Application Notes, section 4.2 states:
When I measure RCAP, it is pretty much 0V. Does this mean the chip is dead?Measure voltage of RCAP, it should be about 1.3 V. If it is 0 V or the same as operating voltage, there is a problem with VS10XX’s analog parts.
I am using the hello.c example as a reference. I have used the same settings except changed the CLOCKF to 0x9800 for my 12.288MHz crystal, which is not oscillating right now either.
