Can the VSM simulator handle multiple-slot programs for an X2? It doesn't look like it: you can only specify a single .bas file under "Picaxe Program File" on each chip, but I would love to be told that I am wrong. John Geddes

FAQs say: "The PICAXE X2 parts include 256 bytes of table data, similar to EEPROM data memory but read-only." Slot-users beware. The TABLE data is stored in Program memory. And if you are using multiple slots that means that TABLE data written in one slot cannot be accessed using READTABLE in...

I have hit a problem with a program for a 28x2 using Programming Editor (both under v5.5.0 and latest v5.5.1]: Syntax checking returns a complaint that my program is too long - by a NEGATIVE number of bytes. Error: Memory full - -251 bytes over. Remove the 'table' command to release 256 more...

If I want to specify pin directions for a port (eg let dirsB=%11110000), but the port includes the two i2c pins - do I specify these as Input or Output (or doesn't it matter?)? John Geddes

I want perhaps a dozen Picaxe-based modules to communicate within a building - and to simplify cabling, would really like to do this using a single bus - preferably using cat5 cabling. I don't need fast data rates - just the ability for a Master to collect a couple of bytes from one slave and...

By trial and error, I have discovered that i2c signals will fail if the i2c wiring is connected to a Picaxe which is not grounded. Is there any simple Picaxe-based or electronics-based way round this? Background: I have built three modules, each with a 20x2. Module A is Master, B and C are...

Can anyone point me to a source of the sort of peelable coating used on the non-component side of Picaxe project boards (in the one I have, a red, foamy substance, but from the notes, sometimes green)? If it could be safely applied in a "kitchen table" environment, it would be an attractive...

I am designing a controller that uses several inputs (including a hand-turned Rotary Encoder and a DS1820 temperature sensor) and outputs to an OLED and to other control units. My first experiments with M2 chips suggest that I might be better using separate PICAXE chips to: A) watch the...
