bought the ar9x,

hi joao, i believe it is the 16mhz version, well enough is enough cant thank mike b and joao enough for there support and time on this project but im now officially retiring it, im going to read up a bit more on the ar9x board and hopefully purchase one later today or tomorrow, on the bright side i ...

hi mike, ive never got the sd card to list the files on this arduino module(or the other 2 ive built) using an ftdi even after soldering the six pin header and connecting ftdi directly with nothing else connected, ive tried flashing card info sketch on to it but its never once flashed correctly, ive...

Sorry guys
My mistake apologies will do more research.
Cheers eddie

seriously thinking about the ar9x board only thing im not sure of is using my djt module, ive read 45 pages so far on the ar9x forum but theres not a lot of info on the djt and ar9x(unless i havent reached them yet),as i said earlier the way my djt module is modded it has a couple of resistors in th...

renewed and checked all the sd card leads with multimeter from arduino board to sd card reader all fine,
i couldnt solder them as i needed them for flashing new firmware.
the results from next test mike,
cheers eddie

hi guys ive been looking for a schematic for the sd card module im using, and ive come across this article about there being problems with this module and spi devices with the fix, dont know if its relevant,but in the meantime im going to solder all my connections from the arduino to the sd card, (c...

mackem54, Maybe you can look at the upgrade Ar9x board (http://www.ar9x.net/) which has sound built into it ? Would save you from having all the troubles. Bob B. wish i had seen this about 2 weeks ago bob been looking at the forum about this, couple of questions if you dont mind, firstly my frsky 9...

there you go mike,
cheers eddie

ha ha so am i joao, ive tested the sd card with read and write it came back as ok,ive tested it with sd card info everything came back ok,i actually bought a new multimeter to test all the components on both boards(actually had to send it back because it wouldnt stay switched on) so got another bett...

ive never had a sound except noise out of the speaker,with ftdi connected and without ftdi connected,
cheers eddie

hi joao,
after flashing mikes test i firmware i connect it all back together then power it with my 12v flight battery to see if theres any sound, then connect the ftdi to serial rx and tx still powered from the battery to read the serial output for mike to look at,
cheers eddie

update reread sketch and it says cs pin is 4 so connected cs pin to pin 4 and it came back as test successful,
ive checked voltage on the 4 pins and they are cs 5.1v dropping to 0v then back to 5.1v when code changes,mosi 5.1v never changes,miso 0v never changes,sck 0v never changes,
cheers

well joao, i loaded a read write sketch to the standalone arduino that had been showing card info successful earlier, and after the upload its supposed to show the files with test results, on opening serial it comes back as card failed to initialise, will try and find different card for next test, c...

hi joao,
i will see if i can find a sketch that plays something from sd card,
as i say i get the right results when checking using the arduino thats standalone, but i cant programme a sketch using arduino to the one thats part of the module,going to try your suggestions ,
cheers eddie

hi mike im just about ready to bin this, ive put in google how to check connections for sd card from arduino via level convertor and what ive read i dont really understand, my understanding is that a serial convertor changes the voltage either up or down, i have a level convertor and i assume im sup...

cheers mike i will check everything and try a different card,
eddie

and he next one,
cheers

next one mike,
cheers

and the next one,
cheers eddie

next one mike,
cheers eddie

mike ive just been having a playabout with the sd card module and the new arduino,when i setup the sketch for the sdcard info i had to change the chip select to no 10, dont know if this has any bearing on your code,
cheers eddie

ok mike,
i flashed it back to the version before this one to see if anything has changed and the second pic is that,i then flashed it to the next version and thats pic 1
i reset the arduino as you can see in the process,

next one mike, i was wondering if the arduino board is ok maybe the amp board isnt so i desoldered everything and checked with a multimeter everything as it should be, i didnt know how to check audio chip so i built a simple audio circuit on a breadboard and it worked fine chip and speaker so someth...

cheers mike hope you had a good day,
eddie

as requested,
cheers mike

cheers mike,
really sorry for using all your time like this,
eddie

managed it

dont know why but it wont let me upload pics ok mike the new code is
03 heart 09 4 blanks 11 < 0 0 C
cheers

hi joao.
im using the pro mini.
i dont have any connections from amp board to sd card, i have arduino board powered from ampboard sharing the vcc and ground with the sd card,same as your diagrams in your first thread
