JE-AN 1286404 Graphical displays
Looks like the driver chip is T6963C and not KS0108.

JE-AN 1286404 Graphical displays
I have some assembler code for KS0108 drivers. I wrote it ten years ago for a CrystalFontz display. The thing that was a bit annoying was that the display is divided vertically in...

Atmega32u4 Interrupt
Enabling Sleep in SMCR is not the same as actually going to sleep.In .asm this is how it's done. sleep_sequence: ldi temp,0x07 ;enable SLEEP in out smcr,temp ;POWER SAVE...

Invalid Register (in my case register Z)
using same registers (ZH,Z) as source and destination might bite you. Assembler datasheet seem to imply that the result is only undefined if the source is pre-decremented or post...

reading adch 5x and average
If you take average of conversions made 2,4,8 or 16 times and so on you only need to use LSR instruction (divide by 2) for divisions.

Seemingly simple RTC problem.
The 2-3Hz thing could be caused by MCU resetting.

controlling two servo via single pin using ATmega32 ??
Should be doable. A servo frame takes 20mS but the actual control pulse(PWM) is only 2ms at the start. Nothing stop you to control other servos on same pin during the remaining...

help switching from multiple analogReads to adc code
Quote:I have been hearing that you should set up an interrupt with your timer (say an OVF from timer 0) and then call each adc call from that inside the ISR instead from inside...
