怎么将iNEMO v2板UART连接到蓝牙

1476 蓝牙

问答对人有帮助，内容完整，我也想知道答案 0 亲爱的大家，我有STEVAL-MKI062V2，我可以使用IAR EW编译代码。电路板有COM连接器（STM32的UART2引脚），跳线J4。 ST说，注意：J4不提供任何收发器;它直接连接到微控制器引脚。因为这可以防止这些引脚上的任何过载/过压。此外，J4连接器还提供3.3 V引脚，可用于为RS232收发器供电。从该引脚吸收太多电流可能会损坏电路板。我想将iNEMO的J4连接到UART蓝牙模块，以便与PC无线连接。我有来自http://www.sparkfun.com/products/9358的Bluetooth Mate Gold 对于基于Arduino的AHRS模块，它具有以下电气连接http://www.sparkfun.com/products/10736 我勾画了下面iNEMO J4的电气连接。我不确定这样做是因为我担心iNEMO可能会受损。如果以上连接错误，请在这里任何人建议我使用上面提到的相同蓝牙模块进行无线iNEMO的方法。谢谢＃inemo-UART到蓝牙以上来自于谷歌翻译以下为原文 Dear all, I have STEVAL-MKI062V2, I could be able to compile code using IAR EW. There is COM connector for the board ( UART2 pins of STM32), jumper J4. ST says, Note: J4 does not offer any transceiver; it is directly connected to the microcontroller pins. As this prevents any overload/over-voltage on these pins.Moreover, J4 connector also provides a 3.3 V pin which can be used to supply a RS232 transceiver. Sinking too much current from this pin could damage the board. I want to connect J4 of iNEMO to the UART bluetooth module for wireless connection to PC. I have Bluetooth Mate Gold from http://www.sparkfun.com/products/9358 which has the following electrical connection for Arduino based AHRS module http://www.sparkfun.com/products/10736 I sketched electrical connections to J4 of iNEMO below. I'm not sure to go with this because I'm afraid iNEMO may be damaged. If the above connection wrong, please any one here suggest me a way to make iNEMO wireless, using the same bluetooth module mentioned above. Thanks #inemo-uart-to-bluetooth 0

答案对人有帮助，有参考价值 0 跳线J4（COM连接器）没有线索知道3.3v或GND引脚的位置。我们必须使用万用表检查它们，然后我们才能找出那些引脚和放大器。其余的针脚。我不知道为什么这个论坛的回复很慢而且很多帖子都没有得到回答。我在COM连接器J4的描述中发现它被记录为UART2，但是当我们看到STM32F103RExx的数据表时，它是USART2＆amp;连接到总线APB1（24/36 MHz）。我可以搞清楚针脚以上与蓝牙模块的连接是正确的。有关更多信息，请访问http://harinadha.wordpress.com 谢谢以上来自于谷歌翻译以下为原文 Jumper J4 (COM connector) is left without a clue to know where the 3.3v or GND pins are. We have to go for the multimeter to check them, then only we will be able to figure out those pins & rest of the pins. I don't know why this forum replies are very slow & many of the posts were not answered at all. I found in description of COM connector, J4 that it is documented as UART2 but when we see the datasheet of STM32F103RExx it is USART2 & is connected to bus APB1 ( 24/36 MHz). I could figure out the pins The above connection to Bluetooth module is correct. Find more at http://harinadha.wordpress.com Thanks
