CC3100 uart communication

Other Parts Discussed in Thread: CC3100

Hi,

i'm working with CC3100 wifi module; i use uart interface for communicate with the module from my microcontroller, H8SX1664.
I use rx tx cts e rts signal, i receive data from module, i ping the module but i don't be able to connect with the module.

I'm stopped in init module; the last packet that i receive started with 0x18 0x25......

Someone could help me?

thanks

Hi Joseph,

thanks for your reply.

I already read the document CC31xx uart, the communication between microcontroller and CC3100 is ok!

I arrive to De-Asserting RTS line after the reception of first byte, with the oscilloscope and in the rx buffer i see some byte, but i don't understand if the data are processed correctly.

I use RX interrupt?and in the interrupt i call CC3100_UART_ISR function, is it correct?

thanks,

Marco

Hi Marco,

Please see the porting example for the MSP430F5529LP in the SDK (board.c). This shows how to properly call the Simplelink driver interrupt task from the UART ISR

Hi,

this is my situatio actually:

- i receive the command 0x0880, i receive all data;

- i receive 0xBA, the RTS go HIGH , with the oscilloscope i see 0xDC BYTE after 0xBA, i think this is corret, but the RTS line is always high.

For all data i have this transition:

0xBA, RTS High, RTS Low, 0xDC and after all data.

Some ideas?

I use 2 interrupt:

1 for RX Serial data

1 IRQ for INTR line of the module

is it right?

thanks
