metherp I just flashed another pico board and it behaves like expected. OK. Then I connected old one, made option run OFF >> then ON like you advised; edited, saved , power OFF>> ON and yes, changes are there. Still, as new user, I don`t get it. And other new user might be confused. User manual says "On the PicoMite the program is held in RAM. When you are editing the program, you are editing the image held in RAM ***** The firmware will also save a backup copy of the program to a special area of the flash memory and this will be automatically restored to RAM on startup following a reset or loss of power. The result is that the user is unaware of the volatile nature of the RAM." So that is "special area of flash memory" is 11 or whatever it will be named? If yes, then I was mistaken by FLASH LIST 1-10 . I was sure 1 is main entry point and other like reserved slots. Thank you metherp |

You are better thinking of Flash 1 to Flash 10 as file stores. You can save one program per slot. As an example, you can use OPTION AUTORUN 5 to automatically load and run the program stored in Flash 5 on power up, if you wish. If AUTORUN is set to OFF then, on power up, the contents of the special flash area are loaded into RAM ready for editing. The special flash area contents are updated when you press F1 (Save) or F2 (Run) in the editor IIRC. AFAIK you can't directly access that area - you won't find it as Flash 11. There would be no point in doing so. FLASH LIST displays the status (and first line) of programs stored in Flash 1 to Flash 10. It's good to make that first line a short REM describing the program.

Looks like GPS(Valid) returns a 1, but the GPS(DATE) has not been set correctly ( This happens very sporadically ) I also noticed , while posting this, that the GPS(TIME) is not correct My Test Code ' GPS Test Program SetPin GP5,GP4,COM2 Open "COM2:9600" As GPS,-4 Print "Hold for valid data...." Do While GPS(VALID)=0 :Pause 100:Loop Print "GPS(DATE):" GPS(DATE) Print "GPS(TIME):" GPS(TIME) Print "GPS(VALID):" GPS(VALID) Print "Hold for fix data...."

FWIW @lew247 and I have been having all sorts of fun and games with Gps(Valid) on the PicoMite: - not always returning 1 even though the hardware says the GPS is "locked" - returning 0 unexpectedly - not returning 1 if queried in a tight loop (which is probably a "daft" thing to be doing anyway), e.g.: Do : ? Gps(Valid) : Loop It's been a bit of a moving target (no pun intended) and when I have a working GPS unit myself (@lew247 has been doing the testing until now) I'll try to provide something more concrete.

Rob please assign a variable from GPS(Date) and then assign that to date$. Then you can do an on error and print the variable. That way I have something to look at This will happen if the parser finds a checksum error in the nmea string. Check wiring Edited 2021-11-05 00:10 by matherp |

You must have missed the output above GPS(DATE):00-00-2000 I have added this , as you asked NDate$=GPS(DATE) Print NDate$ On error ignore Date$=NDate$ Print MM.Errno,MM.ErrMsg$ output 00-00-2000 16 Month is not valid ( I ran it 12 times to finally get the error) is this what you were requesting ?

Tom, I could not get this to happen with my GPS (GT-U7 Compatible with NEO-6M) once locked, I stay GPS(VALID)=1 (I ran your loop code, as is, for > 10 min) Rob |

Rob I've just run your program umpteen times without error Please try testing for GPS(VALID) immediately before the assignment to date$ if gps(valid) then date$=gps(date) |

Much appreciated, thank you. I've been debugging this at arms-length, but hope to have my own working GPS witin a couple of days and then *maybe* I'll be able to get to the bottom of it. Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Maybe this helps, looks like the com buffer hasn't been cleared when the open happens and if it's an $GPRMC as the 1st message, the date is not setup correctly GPS Monitor ON > run Hold for valid data.... $GPRMC,155836.00,A,xx57.91263,N,xx402.57796,W,0.016,,041121,,,A*61 $GPVTG,,T,,M,0.016,N,0.029,K,A*2F GPS(DATE):04-11-2021 GPS(TIME):11:58:36 GPS(VALID): 1 Hold for fix data.... $GPGGA,155836.00,xx57.91263,N,xx402.57796,W,1,07,1.24,343.7,M,-32.1,M,,*63 GPS(ALTITUDE): 343.7000122M 1127.624714Ft GPS(DOP): 1.24000001 GPS(FIX): 1 GPS(GEOID):-xx.09999847 GPS(LATITUDE): xx.96520996 GPS(LONGITUDE):-xx.04296875 GPS(SATELLITES): 7 GPS(TRACK): 0 04-11-2021 0 Thursday 11/04/2021 11:58:36 again (had to paste image, as it has special characters)  Rob |

If that was the case then I should be able to replicate. Please put a pause 2000 after you first see valid and see if that changes anything Please also try with your timezone offset not applied Edited 2021-11-05 03:49 by matherp |

ok, my GPS issue is very very sporadic Yesterday, after your note, I removed the UTC offset and added the delay could not get it to fail (after 30 min) so I removed that logic , to confirm it was a fix and I COULD NOT GET MY ORIGINAL CODE TO FAIL  tried for > 30 min, and gave up in frustration so I tried my original code this AM, third try failed on the Date great, so I took off the UTC offset, and tried again, failed after only 4 or 5 tries ok, now we are getting somewhere added in the PAUSE 2000 could no longer get it to fail  then I removed the PAUSE 2000, added back the UTC offset and now , my original code, will not fail  (been trying for awhile now)I think I'll try again later to get it to fail FYI, easy workaround, is to just try the DATE$=GPS(DATE) with an ON ERROR and loop back to the valid check, as it will pickup the date on the next go around Rob Update: My Original Code just failed with this > run Hold for valid data.... GPS(DATE):03-03-2052 GPS(TIME):13:04:22 GPS(VALID): 1 which IS a valid date, just not a correct one .... (so my workaround would not catch this ) Edited 2021-11-05 23:14 by robscott |

Rob Thanks for all the testing. I found one route in the code that could yield the 00-00-2000 but AFAIK it could only happen with a RMC record with correct checksum but misconfigured latitude or longitude. Your latest 03-03-2052 I simply can't explain unless somehow your GPS is sending checksum correct but data incorrect messages. If you have any energy left for this please try the attached and see what happens PicoMite.zip |

I have now run > 1hr reading data from the GPS looking only at the $GPRMC records, and confirming the Date field is a valid date (today's) so I know it's not an issue with the data stream Here is my Test Code to verify the stream data from the GPS GPS Test Program 3.pdf Update: Just saw your note, will continue testing with your .uf2 THANK YOU for making the Picomite happen Rob Edited 2021-11-06 01:33 by robscott |

Hey Peter in GPS.c You have this if (strstr(nmea, "$GPRMC") || strstr(nmea, "$GNRMC")) { // found RMC char *p = nmea; int i; // get time p = strchr(p, ',')+1; Which could be like this if (strstr(nmea, "$GPRMC") || strstr(nmea, "$GNRMC")) { // found RMC char *p = strstr(nmea, "$GPRMC"); if(!p) char *p = strstr(nmea, "$GNRMC"); int i; // get time p = strchr(p, ',')+1; otherwise, if nmea has garbage, it'll find the $GPRMC, but point to the garbage Thoughts ? |
