RN-42 | ||
===== | ||
|
||
HHKB key switch power control | ||
----------------------------- | ||
MOS FET Nch: BSS138 or IRLML6344T, either works and no apparent difference. | ||
Normally on(pull-up) or off(pull-down)? interms of power saving it prefers pull-down? | ||
|
||
Pull-down will be better for power saving, normally off. | ||

Used Timer | ||
---------- | ||
|
||
8MHz clock | ||
---------- | ||
1) 16MHz xtal with system prescaler div2: F_CPU=8MHz, F_USB=16MHz | ||
2) 8MHz xtal with div1: F_CPU=8MHz, F_USB=8MHz | ||
Hardware USART doesn't work at 115200bps with 8MHz(F_CPU). | ||
|
||
workaround: | ||
a) use Sotwre serial for communcation with RN-42 | ||
b) reduce baud of RN-42 to lower rate;(factory default is 115200bps) | ||
