Posted on July 11, 2013 at 10:18Dear experts.
I am developing RFID reader/tag using STM32L152VBT6 and TI CC1101 using SPI1 interface.
I would like to stop and to restart SPI1 interface to CC1101.
I used the following codes.
The SPI1 interface stops successfully when I call BSP_433_Stop ().
However when I call BSP_433_Start(), I can't receive packets from CC1101 through SPI1 interface.
void BSP_433_Start (void) { SPI_Cmd(SPI1, ENABLE); }
void BSP_433_Stop (void) { SPI_Cmd(SPI1, DISABLE); }
I tried to reinitialize the SPI1 interface when I restart SPI1 interface as follows.
In this case, I can't receive packets from CC1101 through SPI1 interface too.
void BSP_433_Start (void)
{ SPI_CC1101_Init(); SPI_Cmd(SPI1, ENABLE); }
I will appreciate to you if I can be given any suggestion & advices.
Thank you very much in advance.
Sincerely Yours,
Ick-Sung Choi.
