What is the best wireless network architecture for 1000 nodes...?
Sound more like tolerance on the internal clk  from  1. was 10% chips and 2. was 2% chips.

BREQ Instruction Bug
Driving the pin current to the limit, once the led is enabled.... (Which should never happen so.....) Yes you do for 1 us!   Swap the order of the two first instructions....

BREQ Instruction Bug
Perhaps the pull up resistor is undefined, try to disable it when you init the port.     does the LED lit bright? (perhaps it just the port pullup )   add: Forget...

BREQ Instruction Bug
How big is the serial resistor on the LED? , sounds like it's not there ;)     Add: And I expect that you have a 100nF local capacitor between GND and Vcc ;)

BREQ Instruction Bug
How do you power cycle ?   Do yo have BOD enabled ?   For me it looks like a HW reset problem, so it can run at to low voltage.     Add: And how is reset...

UART Rx missing byte issue
How (and where) do you handle the CRC ?   I'm not 100% sure about your needed timing, but for me it sounds like it would be better to deal with the 3 - 0.3ms timing in a...

Amtel studio 7 setting external crystal to 20Mhz on atmega324PB
a  Atmega324PB  can't run  @20MHz with a crystal, it's one of the chips where high power crystal osc. don't work.   Either run up to 16 MHz, or feed it...

Any optimization tips for this...
My question was does a instruction like : CLA CLL IAC RAL   That basically mean load AC with 2, does it take 1 clk or 4 ?   It's just if you want to make it time...

Any optimization tips for this...
I have never looked at the pdp8 before so I had a look at wiki page.   How fast is a OPR instruction, alway as 1 instruction or 1 for each bit that is 1  or it...

Any optimization tips for this...
When I (for fun) was making a AVR emulator running on a AVR, (so code could be in EEPROM or RAM etc.). I did it by reading the two bytes for the instruction (High byte into ZL and...

Getting started ATtiny 1 & 0 series / Application Notes
I had a quick look at the code and have to ask : Don't microchip have any internal guidelines about C style ?  This make me sad to see next to each other: void...

from microprocessor to AVR to SRAM
Instead of dualport RAM, you could look into a true share of the RAM.   I assume that the "real" RAM is fast (like 55ns), so if you do a sync with the AVR and the Z80 they...
