CCS/MSP430FR5739: SPI Large array

Dear team

I am using SPI of MSP430FR5739.

The host sends several K data to the slave each time, and the slave interrupts the reception and writes it into FRAM. The slave reads FRAM pre-stored data at the same time and send back several K data to the host.

How to realize this function? Currently the communication data is placed in an array, the length of the array is not enough.Can I read and write FRAM data in the interrupt program?

Hi Susan, Please find the code example on: MSP430FR573x, MSP430FR572x C Code Examples (IAR and CCS) (Rev. J).

MSP430FR57xx_usci_i2c / SPI/ UART_standard code examples and MSP430FR57xx_FRAM Write code example should be the good reference on your application. Thanks
