RED BRICK 50A with atmega 48
Hello to everyone,
HK has started to sell RBricks with Mega48 wich maybe is less expensive , but the only way to flash is to change the chip with Mega8. A little tricky job. That"s why I was wondering if it is possible to flash and this "new" Atmega48.
regards nikitz
Hello!
Your firmeare does not fit for new HobbyKing RedBrick 50a BEC. It is based on mega48V.
Can you adopt your firmware for it?
Tehnical desription: === BOM === 1x ATmega48v 3x IR2102 12x P0603BD N-Channel MOSFET
=== Defenitions === H = IR2102 PIN 2 (!HIN) L = IR2102 PIN 3 (!LIN) S = from phase wire over 47k+(47k to fround)
=== RC transmitter PWM INPUT === PD2 over 4.7k
=== INTERRUPT === PD6 from a/b/c phase wire over 3x47k+(3x47k to ground)+3x47k
=== PHASE A === H - PD0 L - PD1 S - PC2
=== PHASE B === H - PD4 L - PD3 S - PC3
=== PHASE C ===
H - PD5
L - PD7
S - PC4
=== INTERRUPT === PD6 from a/b/c phase wire over 3x47k+(3x47k to ground)+3x47k
It is not an 'interrupt', it is comparator common.
I have ported firmware, but have a problem with watchdog reset when throttle > 0. Its starts, calebrate limits, pass hardware check, but make 'siren' when I try to throttle up. http://www.youtube.com/watch?v=nYeJDpF74J8&list=UU16DH0BnSvqKmZDr0sN6TLA
Hi delfer, Did you ever get this working? If so can you post the .hex file so I can also use it?
Simon, is this something you have looked into i.e. the port to the new ATMEGA48?
Cheers Ross
