i'm trying to communicate with NRF24L01 RFmodule, it seems that spi init. is ok , but when i'm trying to read for example theREG_RF_CH Registry (0x05) it should return the reset value (0x02) but that does not happen !! it return 0x00 for the first time then atthe second time...
stm32_spi_eeprom_interrupt You can use theopen_systemcommand to open the Simulink® models. For example, use this command for a STM32 Processor based hardware board: open_system('stm32_spi_eeprom_interrupt.slx'); Read and Write Data to SPI EEPROM Using the SPI Transmit Block, the SPI ...

This is the case on all STM32 microcontrollers which have RTC backup registers. More often than not, we can use a region of RAM to get the same result. As long as the system remains powered, the RAM will keep its state even if the device reboots. First, we carve some RAM for ...
