The PUP is a simple handheld console that provides the key elements of a game system – LCD screen, sound and user control – in a handy pocket sized package. It was Winner of the November 2012 PICAXE Project Prize. The PUP is based around a 20pin PICAXE microcontroller. The current version uses...

Hi, Though not documented in the manuals, pin a.0 (normally serial out) is actually usable for the 20M2. This is great as it makes the upgrade path to 20x2 more complete. Issue is support is only available in "direct mode", eg: high a.0 low a.0 toggle a.0 The P.E. has a hissy-fit when...

Hi, This was asked in #3178, but seems not to have been answered at the time. I've been able to "see" the data using 4800,N,8,1 @ 4MHz and a terminal, but I cannot find the format that the data is streamed in. Is this format available to assist in the development of an alternate debug tool...

Hi, If I understand it correctly, given the 18M2 "shares" the eeprom memory with the code memory, shouldn't the following program report 259bytes used and not 3? =============== eeprom 0,(1) eeprom 255,(2) =============== Presently it is a bit deceptive when the program code gets close to the...

Hi All, I can find in the forum equations for the tone generation for values 0-127, but not for the noise function for values beyond this. I've looked at the signals on a logic analyser and can see that the duty cycle seems to be "adjusted", more so than the frequency. Is this true? Is there...

When blocks are collapsed, the find function (ctrl-f or F3) places the screen/cursor in the wrong spot as it does take into account the hidden (collapsed) lines which cannot be seen.

I would think a simple request since every Windows based program supports it since Bill was a baby... Is it possible to add as it frustrates the hell out of me... (I know, I could use Ctrl-C and Ctrl-V... but like every good Windows P.E. should have 27+ ways to do the same thing since the OS...

Hi All, The new M2 chip range sounds great, but the 18M2 now looks a little feature-weak cousin compared to the other newer M2s. Is a catch design planned? extra RAM, more PWM, KB-commands, etc? Are the deficianies hardware, firmware, or compiler limitations? (chose the 18M2 over a 20X2 for...

Hi, I have a 14M project which I have just tried to port to the 14M2 - without success! The 14M project used port C.3 as an output using the "advanced" commands low portc 3 high portc 3 It looks like on the 14M2 C.3 is fixed as input only, making the PCBs I have unusable if I wanted to...

Hi, I'm using an 18M2 to drive both an LCD and an I2C EEPROM using some common pins. Is there a way to turn off I2C functionality and restore normal I/O on the pins so I can control the LCD before and after an I2C action. 1) writing to the I2C bus seems to be Ok as I can afterwards still...

Somehow I thought this chip was to be a replacement for the 18A and 18X chips, yet none of my 18A/18X projects work!!! I'm struggling to find anything in one place that would describe how to change your old programs to work either. * Seems like port B needs to be told its output before...
