  • MSP430FR5849: Signed vs unsigned SPI data

    Part Number: MSP430FR5849 Tool/software: I am working on with a SPI based accelerometer and I am trying to run a function on all of the sampled data. I was able to read all of our data and save it to memory in prior tests but when I attempt to run our…

  • MSP430FR5849: MSP430FR5849 replace MSP430FR5859

    Part Number: MSP430FR5849 Other Parts Discussed in Thread: MSP430FR5859 Hi, Good Day. Customer is currently using a 32.768Khz external crystal with the MSP430FR5849, but he can only source the MSP430FR5859. He assume if he use the MSP430FR5859, he…

  • MSP430FR5849: DCO Error

    TI Thinks Resolved
    Part Number: MSP430FR5849 Hello, When I check the electrical characteristics of the DCO in the data sheet, I see that the DCO error is ±3.5% @ 1MHz. Is this fixed for each individual device? For example, ±1% for device A, ±2% for device B, and so on…
