[quote user="Stanislav Ossovskiy"]When I launch the code it turns out that instead on 15s, all the elements in the declared array are zeros and some garbage!! [/quote]I don't use uVision, but guess...

Thank you for the reply, Chester. Actually I have both those files included in my project. The startup_ msp432p401r _uvision.s file had a reference to a __main function, which was nowhere, so I had to...

View ArticleForum Post: RE: MSP-FET (MSP430: Error connecting to the target: Unknown device)
Michael, In general the errors that say "unknown device" are due to the fact the MSP430 Emulators package is not up to date - i.e., the package does not support your device. Therefore I ask: were you...

Hi, I am working with an MSP430FR5739 , and I would like to know where I can find the values for the decoupling capacitance and if it is possible to reduce it?

Hi Luis, You need to re-write your code to make it work properly. Please follow the C4 example or the other examples provided in the developers package. Checking the events and re-setting them once...

Hi Albert! I'm not aware of a document showing the minimum required decoupling capacitor values. Having 100n in parallel with 10µ connected to the supply pins is a good value you can work with. Only in...

Hi Albert, Recommended decoupling capacitance is 10 uF + 100 nF as shown in Figure 16-11 of the User's Guide ( SLAU272 ) and Figure B-30 of the Hardware Tools User's Guide ( SLAU278 ). Section 5.3 of...

[quote user="Ryan Brown1"]Section 5.3 of the device Datasheet ( SLAS639 ) notes that the capacitor ratio of VCC to VCORE (CVCC/CVCORE) is 10, and since the capacitance required at VCORE is 470 nF the...
View ArticleForum Post: RE: Supplying current with output tied to GND
The MSP merely connects the pin to ground; it is the job of the power supply to sink or source current in the needed amount. As long as the output transistor's voltage drop would not go below that of...
View ArticleForum Post: RE: Supplying current with output tied to GND
I will put it this way. When an output pin is high and connected to a lower potential, it can stand up to about 40mA flowing out of the pin. When an output pin is high and connected to a higher...
