你好,我正在开发一个无线模块EMG,用于截肢者,它将由一些无线模块组成,每个模块具有灵活的有线信道数:“本地的----- -----线(I2C)----- [EMG信道1 ]中心))(模块1)-------线(I2C)-----[EMG通道2 ]处理…(i)(无线)(局部)----- -----线(I2C)----- [EMG通道M-1 ]模块N-----线(I2C)-----[EMG通道M ]每个香奈儿将在16位2kSPS下获得。考虑到每个本地模块的4个EMG通道,它需要192kbp的数据速率[(16bit数据+8位前导)*4CH*2kss]。因此,该项目的要求是:每个模块至少需要192kbps的数据速率——不需要很大的距离(只有几厘米)- Low功率(每个模块都非常低)。大小和电池供电)-时间依赖性(模块需要同步或至少发送带有时间戳的数据)-非常低的延迟(100Ms最大),我是新手,与无线接口一起工作,所以我会感谢一些已经做过类似项目的人的意见,比如什么样的技术No理学(蓝牙、ZigBee、Z波、亚GHz)、制造商、通用提示、ETCRY!!!!

Considering 4 EMG chanels per local module it would need 192kbps of data rate [(16bit data + 8bit preamble)*4ch*2ksps]. So the requeriments for the project is: - at least 192kbps of data rate for each module - No need for great distances (just few centimeters) - Low power (each module will be very low size and battery powered) - Time dependant (the modules needs to be synchronized or at least send data with a timestamp) - Very low delay (100ms maximum) I'm newbie working with wireless interface, so i would appreciate opinions from someone who already did some similar project, like what kind of technology (bluetooth, zigbee, z-wave, sub ghz), manufacturer, general tips, etc Thank!!! |

谢谢!MRF24J40可能工作,但它的250kbps状态。是不容易实现的。Turbo Mode是我从未尝试过的,也许可以添加一些数据压缩,也许。射程和功率都可以。

大家好,我是Bojan Jovanovic。在我目前的项目中,我需要一个低功率的RF收发器,通过空中发送一个小数据包到短距离。在对Web进行了一些研究之后,我决定使用子1GHz的ATA85 10收发器。我知道有一个评估工具包包含在市场上可用的模块(链接)。不过,我想开发一个定制的PCB与ATA85 10芯片在独立的应用模式。另外,如果可能的话,我想使用ISM频段(Slink)的一些SMD天线。请您给我澄清如下:1)如何编程/调试我的独立ATA85 10?据我所知,我需要使用IAR IDE(在Atmel Studio中不可能做到)。我们需要支付IAR IDE吗?2)我能使用ISM频段(link)中的任何SMD天线与独立的ATA85 10芯片吗?有参考电路吗?我知道AATA85数据表的第10页包含典型的独立应用程序的示意图。然而,没有外部组件(电容器、电感器……)的值。3)有没有地方可以从ATA85 10评估工具包(特别是远程传感器收发器板)找到电路板的示意图?非常感谢你的时间和努力帮助我。真的很感激。真诚的,Bojan。
以上来自于百度翻译 以下为原文 Hello guys, This is Bojan Jovanovic writing you. In my current project, I need a low-power RF transceiver to send a small data package through the air to a short distances. After some research on the web, I decided to use sub-1GHz ATA8510 transceiver. I know there is a Evaluation Kit containing that module available on the market (Link). However, I would like to develop a custom PCB with ATA8510 chip in stand-alone application mode. Also, I would like to use some SMD antenna from ISM band (Link) if possible. Would you be so kind to clarify me the following: 1) How to program/debug my stand-alone ATA8510? To the best of my understanding, I would need to use IAR IDE (it is impossible to do it in Atmel Studio). Do we need to pay for IAR IDE ? 2) Can I use any of the SMD antenna from ISM band (Link) with stand-alone ATA8510 chip? Is there any reference circuit? I know that page 10 of ATA8510 datasheet contains the schematic of typical stand-alone application. However, there are no values for the external components (capacitors, inductors...). 3) Is there any place where I could find the schematic of the boards from ATA8510 Evaluation Kit (especially Remote Sensor Transceiver board)? Thank you very much for your time and effort to help me. Really appreciate it. Sincerely, Bojan. |
