Other Parts Discussed in Thread: CC1352R,
Hello,
I am trying to configure both SPI on EUSCIA3 and I2C on EUSCIB0 and I am using TI-RTOS. I can seperately communicate via SPI/I2C but not simultaneously in two seperate threads.
Compiler version - 16.9.11.LTS
TI-RTOS version - 2.20.0.06
XDCTools version - 3.32.0.06_core
This config works for I2C -
var hwiParams = new halHwi.Params();
/* UART HWI */
hwiParams.arg = 0;
Program.global.hwi0 = halHwi.create(48, "&UARTEUSCIA_hwiIntFxn", hwiParams);
/* I2C HWI */
hwiParams.arg = 0;
Program.global.hwi1 = halHwi.create(23, "&I2CEUSCIB_hwiIntFxn", hwiParams);
/* GPIO Port 5 HWI */
hwiParams.arg = 5;
Program.global.hwi2 = halHwi.create(27, "&GPIO_hwiIntFxn", hwiParams);
This config works for SPI -
var hwiParams = new halHwi.Params();
hwiParams.arg = 0;
Program.global.hwi0 = halHwi.create(48, "&UARTEUSCIA_hwiIntFxn", hwiParams);
hwiParams.arg = 0;
Program.global.hwi3 = halHwi.create(42, "&MSP_EXP430FR5994_isrDMA", hwiParams);
hwiParams.arg = 5;
Program.global.hwi2 = halHwi.create(27, "&GPIO_hwiIntFxn", hwiParams);
var hwiParams1 = new halHwi.Params();
hwiParams1.arg = 4;
Program.global.hwi4 = halHwi.create(32, "&GPIO_hwiIntFxn", hwiParams1);
But when I add both HWI for SPI and I2C my application breaks.
var hwiParams = new halHwi.Params();
/* UART HWI */
hwiParams.arg = 0;
Program.global.hwi0 = halHwi.create(48, "&UARTEUSCIA_hwiIntFxn", hwiParams);
/* I2C HWI */
hwiParams.arg = 0;
Program.global.hwi1 = halHwi.create(23, "&I2CEUSCIB_hwiIntFxn", hwiParams);
/* GPIO Port 5 HWI */
hwiParams.arg = 5;
Program.global.hwi2 = halHwi.create(27, "&GPIO_hwiIntFxn", hwiParams);
/* GPIO Port 4 HWI */
var hwiParams1 = new halHwi.Params();
hwiParams1.arg = 4;
Program.global.hwi4 = halHwi.create(32, "&GPIO_hwiIntFxn", hwiParams1);
/* SPI HWI */
var hwiParams2 = new halHwi.Params();
hwiParams2.arg = 3;
Program.global.hwi4 = halHwi.create(42, "&MSP_EXP430FR5994_isrDMA", hwiParams2);
Can someone give me an insight how to correctly configure the HWI when using both SPI and I2C? Thanks
