Posted on October 29, 2014 at 17:07Hello,
I'm using the STM8L151 using IAR workbench without ST Firmware Library and I'm trying to use an SPI Interrupt. Unfortunatey it doesn't work.
SPI is already running, the receiving flag is set, but i don't get an Interrupt:
This is the configuration:
SYSCFG_RMPCR1=0x00; //MIS0->PB7, MOSI->PB6, SCK->PB5, NSS->PB4
CLK_PCKENR1=0x10; //enable SPI clock
SPI1_CR1=0x30; //enable SPI, Baurate
SPI1_CR1_CPOL=0;
SPI1_CR1_CPHA=1;
SPI1_CR1_LSBFIRST=0;
SPI1_CR2_SSM=1;
SPI1_CR2_SSI=1;
SPI1_CR1_MSTR=1;
SPI1_CR1_SPE=1;
SPI1_ICR_RXIE=1; Enable SPI Interrupt
And the Interrupt vector:
&sharppragma vector=SPI_RXNE_vector
__interrupt __root void SPI(void)
{
int a=0;
}
Do i have to enable the Interrupts globally in any Kind?
#spi #stm8l #interrupts
