September 21, 2013 D in AVR backend | ||||
---|---|---|---|---|
| ||||
Hello I've just successfully lit a LED with a atmega88 using GDC. (AVR is a 8bit micro controller with 16bits pointers) I had to change GDC to accept a zero critsize and implemented these stubs for volatile operations on the memmory mapped IO. extern (C) void _d_criticalenter() {} extern (C) void _d_criticalexit() {} The toolchain is using newlib for now. My next step is to try making it with the avr-libc, and then get the IRQs working with the prologue and epilogue generated by it. Regards, Marcelo |

Do let me know how you get on. I expect to see links and patches. =) -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0'; |

Would be awesome to see this as a git repo and/or some howto. After all I used to teach folks basics on MCUs with precisely these chips (and then there are *duinos sold everywhere). -- Dmitry Olshansky |
