| Bug: | |||
| - with Nexus5 keyboard and mouse are very laggy. | |||
| - lose USB connection during power-down mode | |||

| Todo: | |||
| Design: | |||
| - remove MCU dependent power saving code from core/keyboard | |||
| - it should be located in project matrix.c - DONE 11/23 | |||
| - HHKB matrix.c needs matrix_prev? | |||

| ===== | |||
| 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) | |||
