Hi all, I have been working with TIVA C (tm4c123gh6pm), the zigbee modules (cc2530 air module), and rfid (dlp-rf430). I saw that there was incompatibility between them. (see pic below)
The zigbee part with the tiva, works. But when I try to read the information that comes to the coordinator via rfid. I connect the board and nothing goes, until the zigbee stops working. I thought about pulling wires to the rfid plate and so I do not connect them in a stack. But I am doubting the pins that I have to choose. I have tried many, but nothing works for me.

I have connected this pins :
| RFID | ZB+TIVA C |
| GND | GND |
| VCC | VCC |
| 7 | 7 |
| 8 | 16 |
| 12 | 12 |
| 13 | 39 |
| 14 | 9 |
| 15 | 10 |
TIVA+ZB ----> SPI mode.
(TIVA+ZB) + RFID ----> I2C mode.
some help ?
