Hello all,
Im using RF to talk betweeen two arduinos, to light up some leds using TLC5940.
the RF Part is ok, the server send the data and the receiver receives it and display in my serial output
Then i merged the TLC stuff with the receiver.
Then i got a problem, the TLC overwrites the VirtualWire.
I changed the ports on TLC
BLANK -> PB2 (D10)
XLAT -> PB1 (D9)
SIN -> PD7 (D7)
XERR -> PD6 (D6)
SCLK -> PD4 (D4)
GSCLK -> PD3 (D3)
Edited the tlc_config.h and setted
#define DATA_TRANSFER_MODE TLC_BITBANG
Then switched the virtualwires to tx 0, rx 1 then rx to 8, but any case the problem remains the same
When i upload the scketch, commenting the TLC.init(), the virtualwire works fine, but if i leave uncommented the virtualwire stops receiving the data.
The tlc is working fine, just overrinding, or messing with the virtualwire.
Im attaching the source, but dunno if it will help.
any thoughts? Thanks for the help!
