| Oct 19, 2018 at 11:58 | comment | added | Rokta | depend on what you do with information from sensor, if you want to integrate it then interrupt is better, if you want to only display it then it could be in main loop. | |
| Oct 19, 2018 at 11:47 | comment | added | user115094 | Should I read the SPI in the main loop or create a timer based interrupt to read SPI at a fixed frequency? | |

SPIRx does not look like a register definition for STM32. Usually it would be SPI1->RX
