Hello I am brand new to STM32F0xx chip set. I have on board HTS221 and need to read temperature and humidity over 3 wire SPI interface. Can anybody point me in the right direction. Maybe there is an example code on how to setup SPI1 for half duplex s...

Hello, I am new to STM32F0xx device. I have a 3-wire SPI sensor (half duplex mode SDI/SDO).I have created spi_init(), spi_write() and spi_read(). It working but sometimes I get some timing errors where my CS goes high correctly but I am still outputt...

Hello,Thank yo for the proposal on using I2C bus on different pins.Since My hardware is already done, and the sensor was mapped to SPI pins, I had no choice but to use the 3-wire SPI interface. I wrote a bare metal SPI_config() SPI_read() and SPI_wr...

Hello,Thank you for your reply. Our application has 2 sensors and this particular sensor has only one slave address. So we had to dedicate one on I2C bus on the other one on the SPI bus. Yes, this sensor is using 3 wire SPI and my code is mostly work...
