Hello,
My name is Jorge Sousa and I'm developing a solution based in ANT + for my master thesis.
I'm using a pic 18f4680 and the ant11ts33m51b connected with the battery board to the pic like it's in AT3 RF Transceiver Module Datasheet.
What i've done is:
The Vcc and Gnd are common in both pic and module;
The SUSPEND signal is a I/O pin controlled by pic and it's always tied to Vcc.
The Sleep signal is a I/O pin controlled by pic and it's always tied to Gnd.
The Reset pin is also a I/O pin controlled by pic, that i assert (tie to low), wait a little bit and then de-assert (tie to high) to make the reset in ant module. I do this before I do anything else.
The RTS it's a I/O pin configured as Input for pic.
Then I use the USART as asynch mode, 8 bit, non-inverted, 1 start and stop bit and lsb send first at 9600 baud rate.
In the dipswitch present in the battery board I've the following configuration:
1- Vcc
2- Gnd
3- Vcc
4- Gnd
5- Vcc
What happens is that when I do the reset in first place the rts line goes up, then i try to send one configuration command and the rts line just stay still, what should i do to make it response?
The vector that i send is, for example: [0xA4,0x03,0x42,0x00,0x10,0x00, checksum ] - the checksum it's calculated by doing the xor of all previous fields.
A copy of my program it's attached in this email for you can see better what i've done.
Please help me.
