There are many threads about this issue, and I'm sure my solution is buried in there somewhere, I'm repeating it here for other users (like me) who couldn't find the solution after searching. I'm using: picaxe 08M Prolific USB to serial cable AXE091 dev board Windows 7, 64bit A really solid...

I'm subsitituting an 18M2 in place of an 18X in a thermostat circuit. As such, the circuit no longer needs the reset switch or its associated resistor, and I gain an extra input should I ever need it in the future. At present however, this pin is unused (C.5 on the 18M2, or leg 4 of the chip)...

I'm using a GSM module with a 20X2. So far I can send a simple AT query and the module comes back with OK to show that everything's working, so I know my hardware is set up right. To send a text message, I need to send a longer string which includes quotation marks : AT+CSCS="GSM" and a few...

I've built an inside/outside thermometer using an 18x, a couple of of ds18b20s and a hitachi 44780 LCD display. I was thinking of replacing the 18x with a 20x2 as I plan to build a few and the 20x2 is a few dollars cheaper from SparkFun. However the 20x2 does not support the "let pins" command...

I am using a K-type thermocouple with a MAX6675 to convert the thermocouple signal to a digital word, which is read by an 18X using modified code from Peter Anderson's site at http://www.phanderson.com/picaxe/max667x.html When measuring the room temperature my numbers seem about right (around...

So far I've had my 44780-compatible LCD working in the following setups: Serial firmware from www.oatleyelectronics.com 18X-driven parallel operation as in the picaxe manual 14M-driven parallel operation as per Hippy's elegant code at http://www.picaxeforum.co.uk/showthread.php?p=67665 However...

In an attempt to get longer range from cheap RF modules I am trying to use DTMF tones instead of serial data to transmit simple control codes. However I think the RF modules I am using are incompatible with DTMF tones. I remember reading in a thread somewhere on this site that audio signals...

I want to read data from a Holtec HT9170D DTMF receiver (datasheet at http://www.alldatasheet.com/datasheet-pdf/pdf/64510/HOLTEK/HT9170D.html) into a PICaxe 08M. The HT9170 delivers hexadecimal data in parallel over 4 wires. Reading this data directly with the 08M would use all its inputs...

Hello again, I asked a few questions about multiple SERINs on one pin at http://www.picaxeforum.co.uk/showthread.php?t=7139 For those who don't want to read that thread, I have an 08M listening to serial data via a 433MHz wireless module. The remote transmitter sends one byte every ten seconds...

I am trying to build a thermometer for the exhaust on my car. It seems that a k-type thermocouple is the only device that would withstand the 1000+degC temperatures involved. I plan to use a MAX6675 to interpret the thermocouple and provide a digital output for a PICaxe. I've found a few threads...

Hello again folks, I have two serial inputs connected to the same pin of an 08M - one from the 433mhz receiver, and one from a second local 08M acting as a watchdog timer in case the RF link dies... At the moment they seem to have conflicts, and the PICaxe will hang, even though there is only...

Hi all, I'm trying to get two 08Ms to communicate via serout/serin. I can't seem to get any serial output at all. Is is possible to put an LED or a piezo transducer across the serial output pin of the PICaxe... so that I'd get a flash or a chirp when the serial pulse is sent? I'd rather check...

Greetings folks, this seems a bit dim but I've run out of things to tweak. I am trying to download a simple test program from a winXP desktop, (using version 4.1.17 of the program editor) to a PICaxe 08M. I'm using the simple two-resistor download circuit, and I keep getting the "subscript...
