    Picaxe control of Adafruit 14 segment display with I2C backpack

    Adafruit sell some nice 4x14-segment displays with an I2C backpack based on the Holtek HT16K33 driver chip. This thread discussed using the same backpack with a 4x7-segment display and I posted another code snippet for controlling an 8x8 LED matrix. The code snippet below shows how to control...

    New S2Bot version?

    I was just wondering if/when S2Bot will support the new Sbrick Plus? I know it already supports the SBrick output devices, but Vengit's own software is, to say the least, flaky and S2Bot support for the WeDo 1.0 input devices would be much nicer.

    Picaxe control of Adafruit 8x8 LED matrix with i2c backpack

    I couldn't find any Picaxe Basic code examples for controlling this display, but this thread described how to control a 4-digit, 7-segment display that uses the same backpack. Building on the information in that thread, I have produced the following code that demonstrates how to turn on/off...

    Honeywell HIH4000-001 humidity sensor SEN008 - which way round?

    Looking at the data sheet for this sensor, I can't make out from the diagram on p4 of the data sheet which way round are the +ve and -ve connections. I don't want to fry this expensive component so can anybody tell me how to identify the +ve from the -ve? Looking at the photo below, is +ve on...

    S2Bot support for Sbrick Plus

    I was wondering when the new Sbrick Plus will be supported in S2Bot (i.e. sensors). Any news?

    S2P error

    I am using a DE-ACCM2G2 2-axis accelerometer (y-axis) connected via pin C.0 of the CHI035a board (Picaxe 18M2+). I have written a Scratch program using the correct S2P template and it works fine in connected mode. When I try and download the program for "remote run mode", I get this error...

    Location of resistors on CHI035a High Power Board

    I need to remove the R1, R2 and R4 10k pulldown resistors from my CHI035a board. Trouble is, I don't know which is which. I think the label for each resistor is printed on the board but, once built, the resistor covers up the label. Does anybody have a picture of the unassembled board that they...

    "Refresh ports" in Picaxe Blockly Windows Desktop

    If you forget to connect the AXE027 cable before you launch Picaxe Blockly Windows Desktop, there is no way to "refresh ports" like there is in the PE6 version. It seems that the only way to select the correct port for the cable is then to exit and restart Blockly. Could this be fixed in the...

    dirsB and let pinsB not implemented in S2P?

    The blocks below work in "remote run" mode but not in connected mode. Is this a bug, or are these BASIC commands just not implemented? I'm trying to drive a stepper motor in S2P and using dirsB/pinsB will be quicker than other methods of generating sequences

    Read ultrasonic block not working for 28X2 in Blockly for Picaxe

    I'm pretty sure that the "read ultrasonic" block in Blockly for Picaxe doesn't work on a 28X2 processor. The code below works fine on an 08M2 but doesn't work on my AXE401 with a 28X2 fitted (the value of VarA is shown in debug as 33792 regardless of the position of the SRF005). The same...

    Negative temperatures in S2P

    According to the S2P documentation, the Temperature sensor (based on a DS1B20 sensor) can measure temperature in degrees Celsius from 0-120. I was wondering why there is this limitation, when the DS1B20 sensor operates from -55 to +125 degrees Celsius and Scratch can handle negative numbers?

    Megaprocessor - slower than a PIcaxe and a lot bigger

    Megaprocessor - slower than a Picaxe and a lot bigger I know this is not strictly Picaxe-related but should interest the folks on here. A man in Cambridge has designed and built his own mega-microprocessor using discrete components (including 42,000 transistors, 50,000 resistors and 10,000...

    Blockly Windows app - debug

    I want to use the Blockly Windows app at my Primary school coding club because of its simplicity and uncluttered screen. However, the debug screen (as per the attached) is very complicated-looking and doesn't show the variables' symbolic names. Is there any way around this? If not, could this be...

    PE6 variables panel - how do I select dec/hex?

    In the attached screenshot, when using debug, I can see the hex values of variables but not the dec values. How do I show dec values?

    Ultrasonic not working in S2P?

    I haven't used S2P for a while but I've got a new project that needs it so I downloaded the latest version today. However, I can't get the ultrasonic sensor to work. Maybe I'm missing something obvious, but the attached photos show the Scratch blocks and the circuit board. I put an LED on C.1...

    Help needed with Picaxe maths please

    In post #2 of this thread, Boriz uses what looks like some very compact code but I can't get my head round the Picaxe maths. Please could someone translate these two lines into conventional maths and explain it for me? I have tried reading the manual but I still can't understand it. b1=b1+2 max...

    AXE408 robot shield and Blockly

    A suggestion for Technical.. The pin naming for the AXE408 robot shield is inconsistent in places with the pin naming for the AXE401 shield base, particularly the S0 to S7 pins, which correspond with C.7,C.6,B.2,B.0,B.1,B.5,B.6,B.7 respectively. In Blockly, it would be good if you could select...

    Blockly for Picaxe limitations?

    I have been playing with Blockly for Picaxe for a while and have come across some weird behaviour when compiling and wondered whether there are some limitations as to the maximum number of blocks or embedded loops in a program. An example is a program that I have (with a lot of nested loops)...

    Wearable Picaxe anyone?

    Sewable PICAXE Control Board Quite a good price for a 14M2 board in any case.
