    GPS NMEA, Failover Circuit upgrade attempt.

    I don't think its wrong, I just worry that the picaxe wont pickup the serial data. But we shall see. I think I might of finished the program, just checking it through :)

    GPS NMEA, Failover Circuit upgrade attempt.

    That's okay :D just understand that the GPSA sentence is being read properly by the picaxe, nd I can parse the sentence to read what we need. I'm not the best teacher and cannot explain things well. Otherwise I'd help you understand abit more whats going on with the code. At this point, if...

    GPS NMEA, Failover Circuit upgrade attempt.

    There's only one other sentence pattern which could go through and give us bad data: $GPGSA,A,3,19,30,20,13,,,,, If this sentence is received b0 will not read ',' and we can filter this out using an IF statement. I've managed to simulate SERIN and parse the data as hoped.

    µC - Temperature Sensor DS18B20

    I was able to get a presence signal back from the DS if thats what you mean, after that nothing seemed to work. The presence signal is the first step, after that however.. there is a huge amount of code before I receive anything back from the DS. So it's difficult to determine which part of the...

    Thank you, I almost gave up.. but this just might be what I need :rolleyes:

    Looks great! :D is it some form of radio?

    GPS NMEA, Failover Circuit upgrade attempt.

    I've started writing some code, although I do not know how to create a variable for the following: GPS1_Signal GPS1_Data GPS2_Signal GPS2_Data The program reads each GPS serial input, each number/comma/dot data is dumped into b0, since they are not used. b1 contains our 1,2 or 3 value for...

    code for running 2 relays using 2 push buttons

    I've added and modified some parts of your code. See attached. You have not setup the input and output pins, this should be defined first. Then set at the start of your main function, I've added these to your txt file. You also end the main function early with a parenthesis '}', I've deleted...

    Who needs SolderMask !

    The pictures you've shown are very big, and the board looks much bigger than it really is. Therefore it makes it very easy to judge the soldering based on an average board size. Its not easy soldering this precise, however there is always room for improvement. I agree that 1/3 of the solder...

    code for running 2 relays using 2 push buttons

    What programming language are you using? C, Assembly? Have you managed to write any code to operate the relays using switches?

    GPS NMEA, Failover Circuit upgrade attempt.

    Yeah, I understand what you mean. You can create a variable which you can keep in the range of 0-3. Increment when there is a bad sentence, decrement when there is a good sentence. If the variable reaches three, the necessary action is taken.

    GPS NMEA, Failover Circuit upgrade attempt.

    I've been looking at all the samples you've given, too see whats common in every $GPGSA sentence with no signal, compared to the ones that all work. I It seems every working $GPGSA sentence which we can use, seem to have a number 3. Those with no signal, or missing data which we cannot use...

    GPS NMEA, Failover Circuit upgrade attempt.

    Of course ;) its called brain plasticity That's right we can use any pin. I think we need a small signal diode if we use a different pin. Like shown below. However I'm not sure if this only applies to 08M picaxe.

    GPS NMEA, Failover Circuit upgrade attempt.

    Those GPS logs look very consistent, which means we can use the method I described earlier to extract the DOP from the nmea sentence. The conditionals of a program are very straightforward to setup and are reliable since its just logic and if statements. Parsing the data from the nmea...

    GPS NMEA, Failover Circuit upgrade attempt.

    It seems 'hserin' stands for hardware serial in. It uses the designated serial in port and the integrated hardware to read the serial communication. Whereas 'serin' is software based and does not use hardware to read the serial communcation. Which means we can use any pin. I imagine the 'serin'...

    Okay, then its just where you want your buzzer. I'm not sure what hserin is used for :confused:

    GPS NMEA, Failover Circuit upgrade attempt.

    Okay, I've never written picaxe code so learning as i go to help you. According to a few things I've read, you dont have to use the Serial Input pin to read serial. You can use any pin. So it may be a case of just connecting both GPS #1 and GPS 2# data to there own picaxe pins.

    GPS NMEA, Failover Circuit upgrade attempt.

    This guy has written a pdf that shows how you can use the 'Serin' command to obtain a sample of nmea data. The $GPGGA qualifier is used, so the program only samples that specific nmea sentence. In your case this would be '$GPGSA'. The bits (b0) is used to skip the comma character you don't...

    GPS NMEA, Failover Circuit upgrade attempt.

    The most difficult part would be programming the picaxe chip to read NMEA data using Serial In. But settings up the conditions to switch the relays would be simple. This is what I imagine your circuit to look like from what I've read: Relay 1 is used to switch between reading GPS #1 and #2...

    Music Keyboard - Increase Sustain/Decay Time

    Now you've mentioned envelope.. It appears I meant release time according to this graph. The decay once the key is released. It's a shame though, most cheap keyboards are the same. Maybe I'll have to save some pennies.
