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...

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...

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...

Can someone give me a picaxe math code example of how to extract a square root number from a a ADC reading. For example lets say ADC = 4900 which equals SQR 70, how do i calculate the 70 in picaxe math. Yes i know the X1/X2 range of chips has the SQR function, but in this case its a 18m2 chip...

I think it has been asked several times what is the raw pic used for the 08m2 picaxe, but i was unable to find the answer. I would like to wipe a 08m2 and program the basic pic for a small application, and would like to know what pic is actually used so i can read the data sheet to see if it...

Has the 08m2 (version 4.A) got a serin problem with baud N4800 at 4 meg. I have a Dorji wireless module sending serial data to the 08m2, and at 4M , 4800 (N4800_4) all i get is zero in the data, but at 8M (N4800_8) all works perfect with the incoming data, the Dorji module is 4800 baud. I...

When using Let PinsB = 0 will all pinsB be effected in this code example. let dirsb = %00111111 High B.6, B.7 let pinsb = 0 Or wil B.6 and B.7 still remain high as i want them to. I am unsure if the "High" command is ignored in the pinsB statement if those pins are not set in the DIRSB...

With the DS18B20 temp sensors and using a 08m2 chip, can 3 x DS18B20 sensors be used, with one on each of C.1, C.2, C.4. From what i understand from the manual this is doable, in the past i have only needed or use 1 sensor on a picaxe. Application............. I have some solar hotwater...

With the 08m2 can sertxd be used once a hsersetup command has been used? What i want to do is receive serial data using Hserin, but as both pins of hserin and hserout are effected with the hsersetup command, and with the Hserout pin also the same pin used for serial out (C.0), can the sertxd...

Its not something i have given a lot of thought to, and this may have been asked many times... Can a picaxe be programmed by another picaxe with the required program loaded into it? Reason for the question is i have several remote circuits that from time to time i need to change the program...

Non picaxe, but a very interesting concept that some forum members might find interesting or usefull. Its a wireless tag system that you can monitor anything over the internet, web, ipad, iphone, android. http://www.mytaglist.com/index_ie.html

While on flea bay i came across a supplier in the UK with fair prices on some items. Phenoptix is the name. I noticed they have a good range of Kynar wire, this is excellent wire for vero board and circuit board mods. For vero board i solder it to the underside of the board and it makes neat...

Im using a bluetooth module (as sold on ebay everywhere) and a usb bluetooth adapter (standard little 1/2 moon adapter) i can get the bluetooth module to pair with the adapter and a input (com 8) and output (com 7) com port assigned, both show up in the bluetooth device listing, and under device...

When using Hserin with a 18m2 i am a little miffed to the values that are received and was wondering if someone can explain how the values relate to the data sent. Example:- i send a "R" via serial and the value received with serrxd is 82 or R as expected, now using Hserin reading the same "R"...

Recently i needed an inverter for use with a USB to TTL adapter (CP2102) and as most common inverter chips are hex inverters with a large than needed package i decided to use a smaller dual opamp LM358 (8 pin chip) its a common opamp that will work from a single supply. I tried it with the...

When using System Variables (s_w0 to s_w6) with a 20x2 chip, is there a reason i am missing to why i get an error if used with a bintoascii command. The syntax error is, "Word Variable Required" but s_w0 to s_w6 are word variables, what am i missing here?? If the code is changed back to a...

I have a need to have a reasonable amount of chips pre programmed (on going), and some time back i remember a comment that rev-ed will offer this as a service for quanity orders. Do anyone know what the minimum quantity is and what charge for this service. Also where do i find the information...

The 20x2 has a common problem (never had one yet that has not) of needing the calibfreq adjusted to eliminate errors in data from sertxd or serout commands. My question is the manual says from +15 to -15 is the range set able on calibfreq, but i have a chip that requires -30 on calibfreq to get...
