Re: ESL UART与RF问题

目前我的做法是在UART接受中断时失能RF的中断,直到UART数据接受完毕后再使能RF的中断,目前测试不会出现UART数据错乱的问题了。只是如果uart接受的数据量比较大时,由于一直不处理节点的数据,会导致节点一直发送请求数据,可能会导致节点的功耗偏大。

ESL UART与RF问题

我把ESL的USB通信修改成了UART接口来和外部的MCU通信,UART使用的是非DMA的模式。UART RX中断开启,TX不使用中断,采用查询的方式发送,发现当RF和UART都持续接受数据时,UART的数据会混乱,如果RF不接受数据,则UART正常。 询问贵公司的FAE,回复是UART和RF是不能全双工工作的。 如果是这样那UART和RF就只能分时工作了,即uart开启时RF关闭,RF开启时UART关闭。 测试时,当我认为UART接收某个指令时,调用RF关闭函数。函数如下: void gataway_close(void) { IRQ_Disable(); IRQ_RfIrqSrcClrAl...

ESL 通信抓包

最近在调试ESL系统,但是getaway端加入了UART后发现和节点的通信不是很稳定,我想抓下数据包快来分析,想问下有没有什么抓包的教程吗?

ESL 快速入门中的wen提

各位好,最近在学习和使用基于ESL系统。根据ESL_Quick_Guide,我往node写入了ESL_NODE_DEMO.bin文件。读取0X1C000的地址8字节显示是ff ff ff ff ff ff ff ff,往0X1d000写入0102030405060708,然后再去读0x1d000 地址,发现显示为00 00 00 00 00 00 00 00,而且节点屏幕也没有任何显示。 问题1; 节点的供电是否可以由烧录器接到节点的 3.3V SWD GND的三根线中的VCC直接供电? 问题2:烧录ESL_NODE_DEMO.bin后,节点屏幕正常的话是不是应该直接显示一些图片,还是说要往0...

TLSR8359F512ET32 Frequency Error calibration

Dear FAE, We are using Telink 8359 ESL solution. I'm doing the EMI test, in which I find that the frequency error is not normal. I think I forget to calibrate the internal load capacitors . Since The x-tal I used is 24MHz_12pF_20ppm_3.2*2.5*1.1(Max)mm, with no external capacitors applied to it. And ...

Re: TLSR8359F512ET32 EMI Test

Attention!
This question has already been solved.The config of the test equipment , IQ2010 , is not set properly. And now it works fine now.

Re: TLSR8359F512ET32 EMI Test

By the way, please upload 8359's EMI test bin file. Currently, I tried "kite_emi_V1.6_20181214.bin" and "8258_BQB_TX_A2_RX_A0_BUAD115200_20181015.bin" downloaded from WiKi.

TLSR8359F512ET32 EMI Test

Dear FAE, I'm using 8359 ESL solution. Now I need to test its EMI performance. However I can only find three chipset config.ini files, 8258.ini, 8266.ini, 8267_8261.ini, in EMI_Test_tool_V1.5 version. And I tried all of them to make 8359 EMI work. But none of them fit. Please upload 8359's EMI test ...
