Hi, I am working on a project that I need to send data like this out to a SpeakJet chip: \0RX\011J 0NX\012J 0NX\013J 0NX\014J 0NX\015J 0NX\00J 88NX\01J 0NX\02J 0NX\03J 0NX\04J 0NX\05J 0NX\06J 0NX\07J 96NX\08J 0NX Just plugging that line into a Serout command doesn't seem to work ... the...

Hi, I want to figure out how the hardware on my Altair 8800 computer communicates with a Serial Drive Server app running on my Windows 10 PC. Essentially, I need to see how to select one of four .DSK files and read/write to a .DSK file on my PC from CP/M running on my Altair 8800 computer...

Hi, I have an old keyboard chip for a Sol-20 computer. I want to make a simple little circuit with a PICAXE chip to take the standard USB keyboard and translate the keys to drive the Sol-20 computer keyboard chip. Essentially, 2022 USB to 1975 7-bit ASCII out. I don't know how to read the...

Hi, I'm trying to figure out how to have a PICAXE 28x2 chip get a data stream from my PC on the serial PIN 2, then send it out via bit-banging another PIN out to an old computer byte by byte with a clocking toggle on another PIN after each byte moves through the 28x2 chip 9600 BAUD is high...

Hi, Is it possible to program newer chips with the PICAXE Loader to have more memory for programs, a faster clock? 8K of flash RAM would be really nice for larger more complex programs like this HexBot I made; 20210717 HexBot+Maestro12 Test6 After converting the 3-color LEDs to just...

Hi, I'm trying to figure out how to send 70 different serial data strings one string at a time using a momentary switch. I know how to sense the momentary switch, but I need to send different serial data each time I press on the switch. I can set an integer and increment the integer, but I...

Hi, I've been trying the current drivers, FTDI drivers (confusing website) but I cannot seem to get the AXE017 up as a COM Port although it is in the USB controllers list.

Hi, I am using an Adafruit.com Adafruit MIDI FeatherWing Kit PRODUCT ID: 4740. How do I input MIDI data to a PICAXE 28X2? I want to use serin command, but when I try setting the MIDI speed with; serin C.3,T31250_8,(MIDI) ; Fetch a MIDI Note I get an error; serin...

Hi, Toggling a PIN to drive a stepper motor driver step pin is easy, but how can I multiply the toggles so that one PIN toggle = 10 toggles to the motor?

Hi, I am trying to communicate using I2C to a PIXY2 CMUcam5 ... the PIXY2 docs say I need to send a short series of characters to ask the PIXY2 (address 0x54) to request data; 0xae 0xc1 0x0e 0x00 Somehow I'm not seeing anything happening on either the SDA or SCL line. How do I...

Hi, I have a program that passes data to the PICAXE 28X2 module to react to colors seen in the PIXY CMUcam5. That program works. Now I'm trying to retrieve data from the PICAXE 28X2 module to the PC terminal to see if I can sort out how the PIXY CMUcam5 might drive a robot base to stay...

Hi, When I send a little program down to the PICAXE 28X2 to simply send data back to the PC via the programming/download cable the terminal window doesn't open and if I manually open the terminal window it says the serial port is in use ??? What's wrong? ; 28X2+TerminalWindowTests.bas...

Hi, I can make two motors run, but how do I make the two motors run simultaneously to drive straight forward or backwards? ; 28X2+TB6612FNG+2Motors.bas #picaxe 28X2 symbol PWMA = C.1 ; B.0 Right Motor Speed Control symbol PWMB = C.2 ; B.1 Left Motor Speed Control symbol STBY = C.0 ; B.2...

I bought one of these MAX9814 based Electret Microphones so a loud sound could trigger actions for a robot. I've looked at a few dozen websites for ideas how to make it work, but have not been able to get a usable wiring or software configuration. I've been trying the sample code from...

Hi, I want to send specific data patterns to a 74HC595 chip to turn on specific LEDs and eventually, hold on that pattern ... but this do loop doesn't seem to get me any results ??? Can anybody tell me what's wrong with my little do loop? setfreq m4 ; All M2 parts internal k31, k250, k500...

Hi, I got the basic control of the FDD down ... but now I need to figure out how to create musical tones with the FDD head movements. Any ideas on the loop needed for middle C? RoboGuts + FDD + Thoughts a 531 Byte BASIC Language Program ' PICAXE+FDD+Thoughts.bas #picaxe 28x2 '...

Hi, I liked the older v5.5.5 GUI better. The new v6 GUI will not maintain the window shape/size I set so everytime I open up the program it opens up full screen which forces me to resize the GUI before I begin work. Once we get the app setup for our computer screen, the app should remember...

Hi, My motor runs fine plugged directly into the 5V power source, but the motor doesn't run connected to the SparkFun TB6612FNG Motor Driver board. I've tried this with and without the STBY connected to a PICAXE PIN ... trying to run it high and low. Here is my program so far ... as you can...
