how to upgrade MMDVM FW to new Version (Support NXDN)

https://drive.google.com/file/d/107O-Wf4-OAa1T1bfADaLST-Vsi6iVHuk/view?ths=true

How To Connect MMDVM BOARD to your GM300 GM338 GM950i

A:Using Software,Pi-star,stm32flash,MMDVMCal(come with pi-star)

B:Using Hardware,raspberry zero w or raspberry 2 B+,GM950i

Ps :Testing GM950i is very Stable then old GM300/GM338

1. hardware Connect

Current PTT+GND+RX+TX is Work

2. Using MMDVM Cal To Test if work!

Current MMDVM board have two version ,old fw don’t support NXDN,new fw support NXDN

If you want update

#wget http://www.taozhengbo.com/mmdvm/RPT_134.hex

#stm32flash -w RPT_134.hex /dev/ttyS0

My router is ttyS0,raspberry zero w is ttyAMA0

Caution ,you Must Stop MMDVMHost frist when you Update FW.

When Done ,your fw is new now.

Next Testing Using MMDVMCal  you can see the MMDVM baord is 20180327 new version

If you test USING DMR MD380 pls write TG9 and save .

Then press m to testing DMR MS 1031 Test Pattern,and press Space,Start Transmit ,then ADJUST TX ,if you can hear 1khz sound in MD380( TG9,1)   your adjust is ok, stop ADJUST.

If not Press I ,Change  testing Transmit Inversion,and Try Again.

If DMR testing TX is ok,no need testing P25 Testing Pattern,if you like is better.

MMDVM BOARD Woking Condition:

Power :5V

When testing D-DMR Deviation Mode,you can see TP42 or TX pin is 1.2Khz

Wave in Scope,if TX testing is not good ,pls Try TX Inversion.

Final in pi-star ,is the same Tx Inversion =0 or 1

How To SET RXOFFSET or TXOFFSET

HOW TO SET RXOFFSET(TXOFFSET)

Some board Need set offset,so pls visit  http://pi-star/admin/expert/edit_mmdvmhost.php  or http://ip/admin/expert/edit_mmdvmhost.php  

Change RXOFFSET and TXOFFSET to xxx(500 maybe ok) and click apply.

and test BER <=5% is OK.
