ATmega128 EEPROM wont remember second variable
That was helpful, especially that highlighted part with &NonVolatileChar and & symbol   I misinterpreted what was written in tutorial, it said "And the compiler will...

PC 12V 3 pin fan slows down when trying to connect tacho signal
Hello and thank you,   i think the issue has been resolved (tho the solution increased number of part needed).   After changing R3 to as low as 120Ohm PWM started being...

PC 12V 3 pin fan slows down when trying to connect tacho signal
Just tested it, issue still happens when i connect TACH signal directly to input pin with a small 160ohm transistor to limit current. Also when i was doing tests with simply...

UART data send - mixing bytes
Case closed? I just started looking for hints on other forums and found someone having problem with uart data, and he was using Brays terminal aswell. Someone in that topic...

UART data send - mixing bytes
I just checked uart connection on another chip ICL3232 that is running up to 500000 baud rate. With 3 times higher baud 384000 errors still occur with rate similar to one with...

UART data send - mixing bytes
baud rate i use is 115200. ill look through uart code and ISR routines to see if there might be any conflicts ill also check higher baud rates (i have ttl>rs232 chip up to 1Mbps)

UART data send - mixing bytes
It doesnt seem that anything else writes into result[] (its char result[16]). I tried making new variable right in main.c and using it exclusively for dtostrf() and then for...
