CC1352 wiring #13

Closed guitar9 closed 4 years ago

guitar9 commented 4 years ago

So this is a little bit off topic. @dzungpv
I want to ask you how to exactly wire the CC1352. I am using zibgee2mqtt. you said to wire Xds110 or later with 4 pin, TMS, TCK, Reset, GND, VCC(3.3V).

in XDS110 there is no TMS. At how to connect the USB Interface?

XDS110 Pin Mapping: XDS110

XDS110: XDS110

CC1352 CC1352

dzungpv commented 4 years ago

Pin number 1, XDS110 do not have VCC so you must power it with 3.3V

guitar9 commented 4 years ago

ok thank you very much. At which PIN I must Power the XDS110? And for Ground I can choose 8,10,12,16 or 20? Should I wire the 3.3 V also at VCC and GND of the CC1352? And where to connect RXD and TXD of the USB interface?

dzungpv commented 4 years ago

Pin 5 of the XDS110 VREF to +3.3V, Ground you can choose any pin. TX pin to IO12 RX pin to IO13

ResetN to Xds Nreset. Note that only wire TMS, TCK, Reset to Xds when you are programing the chip. After that disconnect it and use only 4 pin VCc, GNd, TX, Rx when use zigbee2mqtt

Flashing works fine but when I use zigbee2mqtt I get error Error: AREQ - SYS - resetInd after 30000ms According to this thread I should press software reset button. Do you know how I do this without dev board? Or do you have another idea? I am using CC1352P https://github.com/Koenkk/zigbee2mqtt/issues/2162

You flash the wrong firmare, you chip is cc1352 but 20dbm for 433/900mhz not for 2.4Ghz/zigbee. You must build your own firmware, see the guide in the firmware repo, but choose "znp_cc1352p1"

Cant find znp_cc1352p1. Where can I buy cc1352p-2 chip? I only found cc1352P Microcontroller at texas instruments. I only found CC1352p-2 as dev board.

You can try CC1352P2 variant and disable high power mode, you can see in TI docs https://www.ti.com/tool/LAUNCHXL-CC1352P

And this is my last answer here. You can ask for help in TI forum https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158

Thank you! I think I should first start with Simple SDK Basics. Do you know a good point to start with zigbee?
