Using a 08M2 Trying to page-write to 24LC256 I'm trying to write a program that will load an EEPROM from a text file on my PC ... I'll have a Python program that will shake-hands with the PICAXE, and will then send the text file in groups of 64 bytes ... I'm catching those bytes okay, and...

I have a small shack about 80m from my house ... I recently ran 2 strands of CAT5 cable out there from the house (one for a PC, the other is spare). I've been wanting to play with having a microcontroller out there that I can control from inside the house; connecting it to relays to power on...

Ah, that feeling when your SMT PICAXE powers right up and says, "Hello"...I hadn't built out a Proto PCB with a PICAXE on it yet...worked a treat! And to WestAust: I ended up going with the "traditional" download circuit ... note the through-hole resistors! Now to start tinkering!

If we know the only way our PICAXE will be downloaded to is from a TTL connection (not a RS-232 port from a PC) is the 22k in-line resistor on the RX line necessary? I understand the pull-down is required to keep the pin held-low (and prevent the PICAXE from going into download-mode). Thanks!

I saw this new type of memory from Microchip Serial EERAM which looks pretty cool. Yon can read/write to it using I2C as you normally would...but without limits...if the chip loses power, it quickly writes the contents of its ram to EEPROM (rated for 1M writes) before shutting down...and...

So, I've been looking at the circuit diagrams...and I have a question. Most of the self-powered PICAXE circuits (where a momentary switch powers up the PICAXE, and then the PICAXE itself holds a transistor "on" to maintain power...) show two transistors...the PICAXE drives and NPN which in...

Hello All, I'm looking to read the value of a single-cell LiPo battery using ADC input. the battery voltage will range from 4.2 Volts (fully charged) to 3 Volts (fully discharged). The 20x2 will be running off of 5 volts (through a power boost PCB). Given the LiPo voltage swing is < 5V, I'm...

I've been trying to implement Software I2C on a raw PIC chip (18f24k22)...it's been so frustrating trying to figure out delays, routing, etc... If I were using a PICAXE, it'd be a simple setup command and away I'd go. I need to control a WS2811 light strip via SPI...otherwise, I WOULD be using...

Okay...seems like this should be a simple question...but... What is the conversion from 4mhz to 32mhz when calculating a pause? I have an application that has a specific pause at 4mhz (1491)...what would that be at 32mhz? 1491 X 8? Thanks!

Hello Gang, I'm working on a binary clock project...and I've used the DS1307 chip as my RTC...I know the stock crystals / chip give about 20PPM performance, and I understand that can be dialed in a bit by using a variable / trimmer capacitor from X1 to GND on the crystal. So, I'm...

Hello Technical / Team, I'm curious why the 20X2 (and other X2 parts) have the ability to be an I2C slave, but not the M2? Is it just a matter of code-space on the chip? Something else? Thanks!

Hi Gang, I'm thinking of a design that will be able to use either a 08M2, or a 20X2...so I've designed a circuit with one download circuit which will go to both chips...so if the 8M2 is populated, it's all set...if the 20X2 is populated, it's all set. However, I've thought there might be a...

Hi Technical, I'm having some crashes on PE6 (running under WINE...so I'm sure that's a wrinkle...) I've sent a crash report...can you tell me what's bombing? I'm not seeing anything in my logs or terminal. Thanks!

Hi gang! Before I go reinventing the wheel... Is there a program already developed to pre-load an i2c memory chip (24lc256) from a text file? I'm thinking of using a terminal program to send to the picaxe at 300 baud... This would give me enough time between bytes to do a page write every 64...

Hi All, Well, I've run into a pickle... I've followed the documentation in the AXE027 document to try and get Ubuntu to recognize the cable...but I am running into a wall. I have another FTDI cable (that I don't use for PICAXE...I don't think it's configured to work with PICAXE) and Ubuntu...

So I'm reading in the forum about the new features that may or may not be in PE6...any update on when it will release? Can we see a list of the new features maybe? I see lots of speculation, but thought I'd just throw the question out there.

Hello All, Is it possible to change the output polarity of the hardware EUSART? (hserout) I don't see how it's possible via the datasheet of the PIC, but I'm new to reading these datasheets, so I may be missing something obvious... I'm know I could set up serial-out on any pin using a...

Hello Gang, I've been using Picaxe for years now, and to be perfectly clear: I absolutely LOVE my Picaxe chips and products! I've been given a nice gift-certificate to SparkFun, and while I'll certainly stock up on a few more 08M2 chips...(Sparkfun got rid of the 20X2! Boo!) I'm also looking...

Hello Gang, Can anybody tell me which pins on a 08M2 are TTL and which are ST? My trusty forum link: Picaxe Input Pin types has failed me, as it doesn't reference the 08M2. I've got a project currently using a TTL input on a 20x2, and I'd like to put one of my shiny new 08m2's to work on this...

I don't suppose there is a way to resize (i.e. make larger) the Serial Terminal Window? I'm pulling in a large serial stream, and just need a couple of more characters of room to keep it all tidy...I'm just asking...please feel free to mock me if I'm missing something obvious. I'm referring to...
