Hi all,
I'm tryng to use SPI in half-duplex mode on STM32F303VC microcontroller.
The STM32 act as Master.
MOSI line is used as data line for input and output.
In my setup I have to send an addr...
Posted on January 22, 2014 at 15:57Hi, I finnally come out with a workaround:after sending the 8 bit address to avoid that data line remains high is necessary to reset the SPI peripheral.Filippo
Posted on January 17, 2014 at 16:41The slave in this case works pretty much like a I2C periperal.I send the registry address, then the preipheral responds with the data.But the problem is another, the SPI data line remains HIGH after the 8 bit trans...
Posted on January 17, 2014 at 13:30Hi, actually I'm not using DMA, nor interrupt to read / write data from SPI.I'm referring to:Half-duplex communication The SPI can communicate in half-duplex mode by setting the BIDIMODE bit in the SPIx_CR1 regist...
Posted on January 17, 2014 at 12:48Hi,it is feasible since the peripheral is configured in Half Duplex mode, as described in reference manual page 723:http://www.st.com/web/en/resource/technical/document/reference_manual/DM00043574.pdfFilippo
