------------------------------------------
Summary: nrf52 ADC will not work if VDD4 reference is specified
Key: MYNEWT-502
URL: https://issues.apache.org/jira/browse/MYNEWT-502
Project: Mynewt
Issue Type: Bug
Components: BSP
Affects Versions: v1_0_0_beta1
Reporter: William San Filippo
Assignee: William San Filippo
Fix For: v1_0_0_rel
There is bug in the nrf52 adc code when VDD4 reference is used. The code is
expecting a global "init_adc_config" to have been configured prior to
nrf52_adc_configure_channel being called (this is called through
adc_chan_config). The BSP's are not initializing this structure. Note that
init_adc_config gets set through a call to nrf52_adc_dev_init(). The call to
os_dev_create() is what calls the initialization function which should end up
calling nrf52_adc_dev_init(). Not sure exactly which structures need to be
passed into os_dev_create() and os_dev_open(); these need to be reconciled.
