我有一个芯片与地址04连接。虽然我能编程,但我不能通过I2C进行交流。
在I2C会话响应中ALFIS是FF- 我的结论是MyPrim3失败了,因为我早上没有用过几个芯片,但是现在它们都没有。 还有一个奇怪的设备列表。有人可以尝试连接连接的设备。 MimPrim3设备列表(使用列表按钮: 设备清单:8bit 7bit地址:地址:06°C 0e 07地址:1a 0d地址:地址:26 13 32 19地址:3e 1f地址:4A 25地址:56 2B地址:地址:62 31 64 32 70 38 7c地址:地址:地址:地址:3e 7e 3f 8a 45地址:96 4b地址:A2 51地址:AE 57广告着装:Ba 5d地址:地址:公元前5e CA 65地址:D6 6b地址:E2 71地址:地址:足总7d EE 77 以上来自于百度翻译 以下为原文 I have one chip connected with address 04. I can't communicate with it via I2C although I am able to program it. During I2C session response alwas is FF- I conclude miniprog3 failed, because I't worked with several chips in the morning, but now it don't wiht neither of them. ALso there is a strange device listing. Can someone try listing devices connected. Miniprog3 device listing (using List button: Devices list: 8bit 7bit address: 0C 06 address: 0E 07 address: 1A 0D address: 26 13 address: 32 19 address: 3E 1F address: 4A 25 address: 56 2B address: 62 31 address: 64 32 address: 70 38 address: 7C 3E address: 7E 3F address: 8A 45 address: 96 4B address: A2 51 address: AE 57 address: BA 5D address: BC 5E address: CA 65 address: D6 6B address: E2 71 address: EE 77 address: FA 7D |

我发现有一个5.01v SCL线的芯片供应达到4.9V
我肯定来自MiniProg。I2C标准并未提及SCL的功率 当做 罗伯特 以上来自于百度翻译 以下为原文 I found there is a 5.01V on SCL line where chip supply is 4.9V I definitely comes from MiniProg. I2C standard doesn't mention about puting power to SCL Regards Robert |

有没有人知道电压意味着什么:在桥梁控制面板状态栏2760mv?
我发现,当Vtarg(芯片供应)是从与SCL和SDA芯片断开 连接电压显示4180mv(虽然输出电压5010mv)。同时SCL 线路电源为5010MV。它就像SCL线电源。 但当Vtarg连接,显示的电压下降到2760mv。虽然VCC仍然是5010MV。 我想在状态窗口电压对SDA线上的一。当MyPrim3断开时,它的应用程序也是一样的。 但是,当连接到芯片的引脚电压为5V,虽然状态窗口显示2760mv 最荒诞的是裸芯片(什么都没有)i2cbridge效果很好 以上来自于百度翻译 以下为原文 Does anyone know what means Voltage: 2760mV in Bridge Control Panel status bar? I found, that when Vtarg (chip supply) is disconnected from the chip with SCL and SDA connected the voltage shows 4180mV (although the output voltage is 5010mV). At the same time SCL line supplies with 5010mV. It's like SCL line power supply. But when Vtarg connected, voltage displayed drops to 2760mV. although VCC is still 5010mV. I think the voltage in status window is the one on sda line. It's app the same when miniprog3 disconnected. But when connected to the chip all pins voltage is 5V, although the status window shows 2760mV The strane is that on bare chip ( without anything) I2CBridge works well |

其次,当我拨动断电的电源引脚不切断电源。
我有一个电路,其中开关电源时,miniprog打开开关。 我希望微型机器人在切换时能起飞。 很好,但突然间,它不想把任何更多的权力。我必须复制USB套接字。 有没有人知道链接老2.05固件呢? 当做 罗伯特 以上来自于百度翻译 以下为原文 Secondly when I toggle power off the power pins don't switch off the power. I have a circuit, which switch on power when Miniprog switch it on. I expected the miniprog to take off power when toggled. And it worked well, but suddenly, it doesn't want to take off power any more. I must replug USB socket. Does anyone know the link for older then 2.05 firmware? Regards Robert |

我认为MIXPRO3的SCL引脚上的电源是电路损坏的原因。
我已经有两个这样的电路板突然停止对MIIPRO3 I2C的响应。 微型机器人本身的信息很少。我有理由说MixPrim3不会孤立。 你从USB接地。 这是可能的,如果地面电势的USB是不同的电源,那么你就有问题。 当做 罗伯特 以上来自于百度翻译 以下为原文 I think that POwer on SCL PIn of MiniProg3 is cause of circuit damage. I have already two of such boards which suddenly stopped responding to MINIPRO3 I2C. An there is so little info in MiniProg itself. I have the reason to say that Miniprog3 doesn't isolate you from USB ground. It is possible, that if Ground potential of USB is different of Power Supply then You have problems. regards robert |

MIXPRO3当切换电源时,非编码地给SCL线供电(当在I2C桥下到USB模式)
我很震惊。这是我没想到的。 我的电路是基于VTARG电源将电源切换到电路板上。 如果VTARG电源上的电源上没有出现电路,SCL线变成电源,在我的情况下损坏电路。 当做 罗伯特 以上来自于百度翻译 以下为原文 The miniprog3 when toggled power on uncoditionally powers up SCL line (when under I2C Bridge to USB mode) I'm shocked. This I haven't expected. My circuit is switching on the power to the board, based on VTARG power. If regardless of Vtarg power on the power on the circuit don't appear, the SCL line becomes power supply, whick in my case damage the circuit. Regards Robert |
