    Controlling a vs1002d with a pic

    I got this chip going around 1 year ago... ah memories... If you want to playback multiple short (known) MP3 files then you have two options: 1. You can preload an SD/MMC card with MP3 files from your computer. This will be stored using a file system (eg. FAT) and thus your PIC microcontroller...

    How to of prototype with surface mount chips

    I've had great success with the SMD adaptor boards from Futurlec plus they are quite cheap. Using their adaptor boards, I've successfully been prototyping a MP3/WMA player using a PIC24FJ256GB106 chip in a TQFP64 package: (Those who are keen eyed might also notice that pin 1 doesn't align...

    FT232BL - USB to Serial Issue

    Note that when using the FT232R (I don't think you can do this when using the [older?] FT232B), you should not have to add inverters in order to set your correct logic levels. Whether positive logic (active high) ot negative logic (active low), FTDI's MProg utility should be used to configure...

    SD Card Troubleshooting

    Here's my code so far. I only really worked on the code for a day or so and as a consequence, it's pretty messy and it's not commented. I'm somewhat busy at the moment but if I can find the time, I'll edit the code and put in some comments. Otherwise, the SERTXD commands should be relatively...

    SD Card Troubleshooting

    I've had a goal to at least attempt some PICAXE-SD card communications for some time now and after looking at some previous attempts (acknowledgements to Hippy and DPG) and despite the problems most people seem to have had, I decided to have a shot at it anyway since I have some time during my...

    SPI Timeout

    I've been trying to interface a 28X1 to a VS1002 MP3 chip via the PICAXE's SPI port, but despite all my efforts, I've come up empty. My program runs fine (setting IO states etc) and gets though the HSPISETUP command (I've tried several configuration options for this command as well with no luck)...

    WA's OBE + PICAXE success story

    Well, I must say that is has been a long time since I've been here. The last thing that I remember was Stan changing user names which I feel was quite a while ago. Anyhow, as some of you may (or may not) be aware, Western Australia is getting into the full swing of Outcomes Based Education...

    SRAM Controller Update

    With a bit of spare time on my hands over this las tweekend, I was able to do a bit mroe work on my SRAM controller. I have since constructed a &quot;refined&quot; version of the original design on a breadboard which can access 256 byts of the SRAM chip's available 32K bytes. All went well as...

    SRAM Interfacing Update

    As per the previous thread (<A href=';forum_id=24&amp;Topic_Title=SRAM+Controller&amp;forum_title=PICAXE+Forum&amp;M=False&amp;S=True' Target=_Blank>External Web Link</a>), I have done some more work on this project, albeit very...

    SRAM Controller

    I have got around to setting up a breadboard with a 32K x 8 SRAM chip (W24257). Of the 13 address lines, I have interfaced 8 of them (thus I can only use 256 bytes of the 32K) and tied the others low. 6 of the IO pins are connected to PORTB of a 16F628 while the remaining 2 are connected to...

    Using SRAM (or NVRAM)

    As part of a scrolling LED message project, I was planning on storing character data and message data on a RAM chip. Why RAM? I will probably be getting the controller to access (read and write) to the memory very often, in which case, a EEPROM would probably wear out pretty fast. The ability to...

    AXE045 Colour Sensor

    I have received an e-mail directly from someone requesting some help regading the AXE045 Colour Sensor. I made a quick reply but I do not see myself very qualified regarding this device (I do not have one myself). If anyone has any ideas, I will forward them (including any credit...) to the...

    IR Receivers

    I was looking at TechSupplies' website and found their &quot;Infrared sensor (LED020)&quot; for &#163;0.42! That's around AU$1.20. Now am I misinterpreting what I am looking at or are Australia's main electronic suppliers all selling these for AU$8.00 each?! Does anyone know where I could get...
