  • RE: MSP430FR2533: Captivate MSP430FR2533 REGISTER_I2C mode issue

    Hi Vaidas, Actually, you can run recalibration in any times you needed. In our library, calibration will run in every power on. Sometimes, when negative touch occur, maybe you can try to run calibration: Thanks! Best Regards Johnson

  • MSP430FR2533: How can I program a Capacitive Touch MCU?

    TI Thinks Resolved
    Part Number: MSP430FR2533 Hi, I am starting a project and want to use mutually coupled capacitive touch sensors to avoid issues with water or humidity. I saw that your MCU solutions are the best for this, so I'll be using an MSP430FR2533IRHBR that will…

  • MSP430FR2533: Controller hangs after longer touch operation

    Part Number: MSP430FR2533 Hello everyone, We have a product which is based on the capacitive evaluation of the MSP430FR2533. Recently we have noticed that the controller hangs when it is cool (approx. 5°C) and is triggered for longer than 2 min. After…

  • MSP430FR2533: different outputs for compression and decompression tests

    Part Number: MSP430FR2533 Hi Team, Good day. I am posting this inquiry on behalf of the customer. I've constructed a basic capacitive sensor, which features a flexible silicone material encapsulated between an upper copper layer and a lower copper layer…

  • MSP430FR2533: Rain drops cause false trigger

    TI Thinks Resolved
    Part Number: MSP430FR2533 Other Parts Discussed in Thread: TIDM-1021 We are using the part in an intercom product with a capacitve touch front. We are suffering from false trigger due to rain drops. Apprecite for ideas how to optimize the driver/firmware…

  • RE: MSP430FR2533: Individual differences in delta values

    The GND will affect the parasitic capacitance. If it is too big that may cause the issue you faced with.

  • MSP430FR2533: Captivate and Digital Input interrupt

    TI Thinks Resolved
    Part Number: MSP430FR2533 As the title says, I need to implement 2 interrupts. The first one is a Capacitive proximity sensor using Captivate design library with LPM3 (Which is no problem for me). The real problem is I need another interrupt, active low…

  • MSP430FR2533: Finding the touch Sensing Variable

    TI Thinks Resolved
    Part Number: MSP430FR2533 Other Parts Discussed in Thread: MSP430FR2633 First of all, I used CapTivate Design Center to setup the proximity sensor to the MSP430FR2633 development board and it is working awesome in GUI, I like the way the graphs are shown…
