Other Parts Discussed in Thread: MSP430FR4133, MSP430FR6989
Hello,
I am using a MSP430FR4133 as master and a MSP430FR6989 as slave in a spi setup. I have it working with the example firmware.
However, when I try to change the settings for SPI it no longer talks to each other.
Example:
UCB0CTLW0 |= UCMST|UCSYNC | UCCKPL | UCMSB|UCMODE_1|UCSTEM;
as the original the UCCKPL = 4000 this makes the 6th bit high or 1. This by the reference manual is setting clock polarity to inactive high.
I need it for my application inactive low. Therefore, I changed the UCCKPL =0000 on both the master and slave.
After I do this I get nothing Received back from the slave.
Can someone help?
