microchip: "328p has 2048KB of RAM" I am so impressed, they have a table listing memory size, and it says "RAM (KB)". I suspect that the person doing the web site doesn't know what AVR chips are, and just... |

TWI/I2C driver code for attiny3216? So, I have seen a couple of AVR i2c libraries, which worked on the 328p, and I've even found one adapted to (mostly) work on the attiny84. However, none of these seem to have... |

minimal circuits for attiny3216? So, I have found lots of diagrams showing "minimal" circuit setups for the 328p or attiny84, but I haven't found a corresponding thing for the 3216. Looking for things like "where... |

Choice paralysis and 3216 programmers So I didn't actually read carefully enough to notice that 3216s don't use ISP anymore, so I need a UPDI programmer, and possibly want one that's HV-capable. And there's... a lot.... |

attiny3216 fuse calculators, etc? So, I got a couple of 3216s to experiment with, because they seem to be cheaper-but-more-powerful than the older chips, but they aren't among the things listed in the fuse... |

attiny84 i2c -- what speeds can/should I expect? I'm using the Arduino TinyWireS library, which is a pretty thin wrapper on top of Donald Blake's usi_twi implementation based on the AVR312 app note. Observed behavior: If... |

What's the A? Was looking at chips, and noticed that the "ATTiny84A" is significantly cheaper than the "ATTiny84", but I can't find actual spec differences. So for instance, on Microchip... |

Dragon hanging at boot with yellow LED I have an AVR Dragon, which I've been using to flash AVR chips. It "stopped working" recently; symptoms are diagnostics about being unable to talk to it in ISP mode from avrdude,... |

Using an AVR Dragon with ISP headers So, I've been reading the Dragon docs, and I've been reading threads, and I clearly don't know *something* but I don't know what it is that I don't know. I found an AVR... |

Trying to make my own USBTiny Okay, this is probably above my skill level, really, but it looked fun. I have a Sparkfun USBTiny. It works. I made an attachment for it which has a pair of ZIF sockets and is... |

Functions within functions (lambdas) Note this thread started at https://www.avrfreaks.net/forum/... where a passing comment mentioned the possibility of using "functions within functions" in C. That triggered the... |
