    Strange Download Problem

    Hi, I have a 20X2 on a homemade breadboard using the download circuit from the Picaxe manual. (I've made quite a few of these and know that I can follow the download circuit.)The download cable is a serial one coming from a hardware serial port on the PC. Battery voltage is 5V. When I come to...

    CRC and Decimal, ASCII

    Hello, I'm trying to use a bit of code which generates a CRC and it is working correctly provided I input the data in ASCII format, i.e. "A","B","C","1", "2" etc or use the number equivalents, i.e. decimal 1 = 49, 2 = 50 etc. The main part of the program generates a data string in the...

    50 baud ASCII output

    Hello, I'm trying to build a high altitude balloon flight computer using a 28X2 and have most of the software written. However I'm getting stuck on the output to the transmitter. I need a 50 baud data stream. I can get 50 baud via HSersetup, but that is a serial data stream with stop bits. Is...

    Long wait preventing download?

    Hello, I'm using an 08M to control the transmit line of a radio and inject an audio tune. This works according to plan and is not a problem. However, I don't want it to start immediately, so have set a 600s gap after power on before the main program runs. initial: for b0 = 1 to 10 wait 60 next...

    Picaxe Hangs - Voltage levels?

    I am trying to read the Picaxe GPS into a Picaxe 40X on the proto board. Power is supplied by two separate 4.5V battery supplies. The GPS is outputting data okay when fed directly into the PC's serial port. I have put a sertxd statement as the first line of the program to test the connection...

    GPS Data Rate

    I'm using the official picaxe GPS module, the Locsense LS40EB which according to the manual comes at a default output setting of 4800 baud, but mine seems to be at 9600 baud, according to the Picaxe terminal settings. Is there a way of resetting it to 4800 baud? Hardware: 40X chip and a 4MHz...

    GPS Modes

    Hello, I have a Locsense LS40-EB GPS module, the "official" picaxe one, and I'm trying to make sense of the different data output modes. I've read the datasheet, but can't find anything about setting the module to a particular mode. Other threads have revealed: 'Use the qualifier "$GPGGA" to...

    GPS Data sheet

    Hello, There is a reference to a GPS datasheet, AXE210_GPS.pdf, on the Picaxe Connect board pages, but the link does not exist. Is the datasheet available or is it still being produced? Thanks for your help, Graham
