Hi, I need to put my Picaxe 20x2 communicating with my computer (windows 7) through my USB port. I also want to use the USB port to communicate and supply my Picaxe. What is the best "cable"/"solution" to do this using only one cable? because with a cable like this I don't have access to the...

Hi, Maybe I will say something that for most of the users is "is already more than well known"... but for those like me... I'll post any way :) When I was "googling" on the internet for a converter online from decimal to binary and to hex I've found that the only thing that we need is to use...

Hi, I want to interface the nrf24L01+ (http://www.nordicsemi.com/index.cfm?obj=product&act=display&pro=94) with a Picaxe 20x2 and I’ve started reading this tutorial made by Brennen http://www.diyembedded.com/tutorials/nrf24l01_0/nrf24l01_tutorial_0.pdf This tutorial is C language...

I know that already exist many posts about Voltage monitor... but after reading all the posts I’m still have doubts :( My rechargeable battery has 3,7v and because of some ICs I will use a 3,3v voltage regulator supplying my 20x2 Picaxe and all the others ICs. I want to monitor the battery’s...

Hi, I "google" about C5A to mA conversion and haven't found anything. Can anyone tell me what is this unit measure "C5A" and how can I convert to mA? (I want to know what is the max discharge current (in mA) of this battery...

Hi, I've an IC that has a reset pin that says: "reset pin has a built-in 450k pull-up resistor. Pulling down this pin causes IC reset itself. Recommendable pull down resistor value is 1k" I will link this reset pin to C.1 (output) pin (Picaxe 20x2) My guess is: until I've the PortC.1 in Low...

Hi, Can you help me decide what is the best way to have the time elapsed between two pulses (picaxe 20X2 or picaxe 18M2)? Every pulse as a 1ms duration, and I think I can have up to 5 pulses per second. I was considering to use the count command but if I use count C.1, 5000, w1, I only be...

Hi, I was searching for this two commands (setintflags and setint) to understand the diferences between them (I will use a 20X2), and then I've found this two links: link1 http://www.picaxeforum.co.uk/showthread.php?t=7506&highlight=setint+setintflags link2...

Hi, I'm thinking use one Xbee module with this battery: http://www.sparkfun.com/commerce/product_info.php?products_id=8818 The problem is that Xbee module only works with 2.8 – 3.4VDC (http://www.digi.com/products/wireless/zigbee-mesh/xbee-digimesh-2-4.jsp#specs) To drop down from 3.7v to...

Hi, Yesterday I opened my garage transmitter because I was curious about: where is the antenna? . The same appleis to the cars remote control... how can they put a transmitter in a key car? If these kind of transmitters use the 434mhz frequency (normally), shouldn't they have a 17cm antenna...

Hi, Because and don't have success put to work my sparkfun transmitter and receiver i will try to use another type of transmitters and receivers. I have found these three: http://www.robotshop.ca/on-shine-high-sensitivity-tx-rx-4.html...

Hi, I bought this transmitter and this receiver and with a 18x Picaxe I want to send data (serout) to a 20x2 Picaxe (serin). This is the code for 18x #No_Data main: for b0 = 1 to 10 '-blink led to see when serout will be executed high 3 serout...

Hi, I am trying to send serout command from a 18x Picaxe and receive with serin command in a 20x2 picaxe. this is the code in 18x Picaxe: main: for b0 = 0 to 255 '-blink led to see when serout is executed high 3 '--commands to make serout work better (without sending...

Hi, If I have 2 picaxes wired and send the serout command from picaxe1: serout 7,N2400,("Hello world! How are you?") What should be the serin command in the picaxe2 to receive all the data? Thank you

Hi, I'm using a 20x2 PICAXE and a 16x1 display (VHC16100) (removed from a samsung fax machine) and i put it to work with this code: #No_Table EEPROM 0,("hello") gosub init main: b1=1 gosub wrins pause 1000 b1=10 gosub wrins pause 2000 b1=14 gosub wrins pause...
