Re: File /!1! Flows by Type/RADIOS/HRD_ve9gfi_2022.06.08.2130.json updated
#file-notice
Hi Adrian, ? I created two dynamic dropdown lists, and each one works. Then I added a Switch node to select what list should be used, based on the getradio response.? ? I'm stuck ... but I wanted to share that this will work for your radio and mine, automatically, if I can get the Switch node to cooperate. I tried using both the msg.payload output from MQTT and the flow.getradio variables... same response (not working). It's Saturday here, and I need to run the roads ...? If you see my error, please let me know. ? EDIT>>>? The one thing that comes to mind is that perhaps the getradio and mqtt string is UTF16 and is not matching my typed in string. Greg VE9GFI ? |

Permissions question...
Hi,
I am trying to read a file under Ubuntu... The file is under my home directory, as shown in the screen capture... I am using readfile, and all permissions are set to read/write for everyone on system, for the target file. I know this is some sort of permissions issue, but I don't know what it is... Any suggestions? -- 73, and thanks, Dave (NK7Z) ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst. Director, NW Division, Technical Resources |

Re: Power Master 2 watt meter flow
开云体育You can set a jumper in the meter or use a Y cable and connect two sensors parallel. The sensor with highest reading will show output.?This is fine for amp output in SO2R but will not show input and output of amp at same time. I set the jumper in the PM 2 meter which parallels the two sensors. Works fine. Dave wo2x On Jun 10, 2022, at 9:45 PM, AH0U <bruce@...> wrote:

? Hi All, ? Making progress with Power Master II watt meter flow. I’ve got metering working as well as alarm indication for high SWR and High Forward Power. These can be set in meter to auto reset or be latching. The alarms light up LEDs in the dashboard and can be reset via a Clear Alarms button. Trying to think of anything else (control wise) to add to the meter. ? 73 Dave wo2x ? |

Programming help needed - CRC8 calculations
开云体育Hello all, ? Working on a flow for the Array Solutions Power Master II watt meter. ? I have most of it working except a couple of commands where I cannot determine the CRC checksum. I am NOT a programmer so therefore I have met my match and hoping some of the brain power in the group may have an answer. ? The meter wants an STX + command + ETX + CRC + <CR> ? I am attaching below the information I received from Array Solutions on how to calculate the CRC. According to their info the CRC is based solely on the payload and not the STX or ETX (hex 0x02 and 0x03). I would like this to be able to be put into a function node to calculate a msg.crc based upon payload. ? If a payload of v? is sent the CRC is 0x42 0x42 hex or BB ascii. ? The below info has the CRC table they use. So looking for someone with programming that can come up with a function to determine CRC for a payload. ? 73 Dave wo2x ? ? ? ? PowerMaster VSWR Meter serial protocol 10-17-06 ? There are 3 baud rates selectable from the meter menu. The default is 38,400, no parity, 1 stop bit. ? The first character of a packet is an STX ($02). This is followed by the packet payload. The payload is followed by an ETX ($03). An 8 bit CRC is appended after the ETX. The CRC covers the packet payload, not the STX or ETX. Finally a <cr> ($0D) is appended. Line feeds ($10) may be added, they are stripped by the receive protocol. ? Here is an example of the packet CRC testing: ? byte CRC_Check(void) { byte *ptr, b_udata, b_crc; ? ptr = c_UserInBuf + 1;? /* skip STX */ b_CRC8 = 0; while((b_udata = *ptr++) != '\0')? /* end of string safety limit */ ????? { ????? if(b_udata == ETX) ??????????? { ??????????? b_crc = MakeHex(*ptr++) * 16; ??????????? b_crc += MakeHex(*ptr); ??????????? b_CRC8 = ~b_CRC8;???????????? /* CRC sent complimented */ ??????????? if(b_crc == b_CRC8) ????????????????? return(0); ??????????? else ????????????????? return(1); ??????????? } ????? else ??????????? CRC8char(b_udata); ????? } return(2);? /* missing ETX */ } ? void CRC8char(byte d) { b_CRC8 = crc8revtab[b_CRC8 ^ d]; /*crc must be complimented elsewhere*/ } ? ? ?

Basics of Node Red Presentation - Arizona Outlaws Contest Club
I gave a presentation to the Arizona Outlaws Contest Club last night, mainly about my contesting dashboard, but they wanted to know more about the basics of Node Red.? I put together about 3 presentations for them and this is what came out of it. I spent a good 45 mins brain dump of Node Red and basic configurations on how to get started.
At the end we talk about the contest dashboard, but I think the first part will help some of the new people get started with Node Red if you haven't already. Kyle AA0Z |
