在LCD控制暫存器 LCDCON 的 bit6 是否有打開?

bit 6 SLPEN: LCD Driver Enable in Sleep mode bit
1 = LCD driver module is disabled in Sleep mode
0 = LCD driver module is enabled in Sleep mode

在 LCD Clock drive 裡有說明,你可以用外接 Timer1 32768Hz 或是使用內建的 31KHz RC震盪器,這樣在Sleep Mode 下 LCD 能可正常工作。

The first clock source is the system clock divided by
8192 (FOSC/8192). This divider ratio is chosen to
provide about 1 kHz output when the system clock is
8 MHz. The divider is not programmable. Instead, the
LCD prescaler bits, LCDPS<3:0>, are used to set the
LCD frame clock rate.
The second clock source is the T1OSC/32. This also
gives about 1 kHz when a 32.768 kHz crystal is used
with the Timer1 oscillator. To use the Timer1 oscillator
as a clock source, the T1OSCEN (T1CON<3>) bit
should be set.
The third clock source is the 31 kHz LFINTOSC/32,
which provides approximately 1 kHz output.
The second and third clock sources may be used to
continue running the LCD while the processor is in
Sleep.
Using the bits, CS<1:0> (LCDCON<3:2>), any of these
clock sources can be selected.

1.進入SLEEP MODE LCD動不了?
2. 如果沒有進入sleep mode 又達不到客人要求的100uA
3. 我做過實驗 32KHZ 震盪頻率什麼是都不做就要600UA
4. 32khz -->sleep mode 也要82uA我不知道 data sheet 的8.2UA 2 V是如何測出來的,真是夭壽,阿豆仔都看data sheet來要求我的,他奶奶的,我會被害死。
各位大大是否有寫過real time clock 我的產品跟casio clock差不多不過要增加一個RF 發射但是平常我是將rf關閉的
可以給建議嗎?
microchip 的FAE可以幫忙我嗎?
嗚嗚嗚嗚。。。。要是讓阿豆仔寫出來那。。。。面子往那裡擺啊,受傷嚴重的是台灣microchip因為單子又會被義大利的MICROCHIP搶走了,快馬加一鞭幫忙一下吧
