RE: M5Stick-V microphonoposted in M5Stick V
uhm, the mic has a design flow
https://twitter.com/M5Stack/status/1164753358101463044- M5StickV will not have Microphone function, which doesn't affect the normal usage;
- For customers who do need this function, pls contact your purchased channel for after service, till Sep. 30;
- M5StickV+ will be released end of 2019, adding Wifi and Microphone function.

RE: M5StickV Firmware_1017 Upgradeposted in Official Updates
im not sure i understand, can u provide an example ?
EDIT: it works now i have to comment out those two:
#pmu = axp192()
#pmu.enablePMICSleepMode(True)when added they the IMU locks up
