Reading a 16-bit word via SPI

In order to read a 16-bit word from a current sensor, is it correct to say: HAL_SPI_Receive(&hspi1, &SPIRx[0], 1, 1); //?SPIRx is declared as uint16_t SPIRx[1];I told CubeMx that the data size for SPI1 is 16 bits

ARM Cortex M4 SVC interrupt causes usage fault

I’m trying to write a context switch assembly on STM32F411E but I encounter a usageFault right after I make a second call to the SVC 0 (in my second task) instruction. The funny thing is the first task can make SVC calls just fine but the second task...

Using the inline compiling macro ?

I have an LCD is on an 8080 16bit FMC interface with A0 register select.I can read the status correctly here:#define LCD1_DEVICE_ADDR (uint32_t)0x60000000 #define LCD1_DEVICE_DATA (uint32_t)0x60000001   uint16_t *pLcdRStatusWAddress = LCD1_DEVICE_...

How to configure I2C2 module on STM32F217ZG?

I have managed to communicate via I2C1, but when I switch over to I2C2 I always get a "Busy" response state from the MCU.Please keep in mind that this is the same I2Cx module from the same datasheet which is set up and executed in the same way as I2C...

Atollic update error during "check update": Cannot complete the install because of a conflicting dependency.

Setting up I2C1 on STM32L152

I'm having a problem which appears to relate to initialisation of the I2C. When I turn on the clock to the I2C1 it sets the busy flag. Sometimes when setting up the GPIO this flag clears, sometimes it doesn't! Could someone point me at guaranteed rel...
