I was recently given 10 x HC340G USB to serial adapters that was purchased by a school complaining they didnt work with picaxe, well we all know why these boards dont sometimes work unless you invert the data lines (serin and serout). Then i stumbled across these RS232 boards, being cheap...

Do you have the setup tool from Dorji, if so then setup should be very simple. As for the first byte needing to be $0 that is not needed, it should except any data sent, so it may be a fault in the setup. The setup tool looks like this. The serial parameters need to be set to the baud of...

Also see this sheet. It pays to read data sheets for other model devices as it often contains information suitable to all model devices........ Chinese instructions !!!

Do these data sheets help.

Here is a data sheet i find a little less colourful but easier to follow for the SAA1064. Im still unsure if the question is to driving a 4 x 7 seg module display, or a larger display made up of 4 x single 7 seg displays.

Some years back i did do a batch of home made PCBs for this driver and 4 x 7 seg displays, i did not do a schematic for the boards as they were very simple. One board took the driver chip and the other board took the display chip, the display board stacked on top of the driver board and was...

Is there a problem with the 18m2 firmware version "A"and background receive, as from my testing with 2 x 18m2 chips , its garbage that is received from one chip to the other. Using the same code in a pair of 08m2 chips all works perfect as one would expect. The basic code is a byte via serout...

Im not sure what the diode in your circuit is doing, as it appears to be backwards if my thinking is correct. Then this is all guess work as we really dont know what the camera circuit actually is. In the schematic below R1 is the pullup resistor within the camera, and R2 is a suggested test...

Because i dont always follow threads, i will suggest a different aproach to consider after you master the circuit you have. This was a circuit i done some years back for a 08m, and which uses the enable pins. Here is a cut and paste of the code example to suit, also showing direction changes...

Can someone tell me whats wrong with this code, as from my understanding it should work. #picaxe 28x2 symbol Adc_reading = w1 symbol voltage = w2 symbol calibrate = 123 symbol adc_pin = 0 adcsetup = %0000000000000001 main: readadc10 adc_pin, Adc_reading...

When using Eeprom with a 18m2 (or any picaxe) and a program that exceeds 1792 bytes, is it correct program byte 1793 is written to eeprom location 255, and program byte 1794 is location 254, and so on. The manual implies that is correct, and im just checking if i have understood it correctly.

Why is there no complete schematics for the prototype boards Rev-ed sells ??? There is often a question on the forum about what pin to wire what to, and code to suit, i have never purchased a Rev-ed board in my life (i make my own PCB's). It be nice to have full schematics for your boards, so...

You are part correct, Vcc goes to the 5 volt supply from the picaxe board and Gnd is also the same as picaxe board, out connects directly to a picaxe input ADC pin. ONE of your motor wires will connect to one screw terminal and the other screw terminal goes to the 6v battery, the other motor...

I dont recall if you told us the brand of alternator, but here is drawing of a bosch alternator showing "W" as connected to 1 x phase and diode gated to ground. It might give you a better idea of how the Alternator is wired.

Did you try reversing the polarity of the led between W terminal and ground to see if it worked both ways (AC voltage) or just works the one way (DC voltage) As you see there is several input options put forward, and any or all will likely work. I tend to work on caution with this sort of...
