Hello Jakub, There are some considerations when working with high memory on MSP430 devices. I am going to move this thread to the MSP forum where the experts there are most familiar with these considerations. Thanks ki

Hello Antonio, No, there is not an MSP430 with integrated CAN. An external CAN controller would need to be used. See the link below for an example. www.electrodummies.net/.../

Forum Post: RE: CCS/TM4C129ENCPDT: Internal temperature measurement setup
You are right, that the charging of the sample capacitor is documented in the data sheet. But it require some very clever reading to understand the sequencers actual sequence. By knowing the actual 'where does it come from' level and input, we can take this into account for precise high speed measurements. Surprising is it, that even when A0 is configured as a digital input it seems to be 'where it comes from input pin' to the temperatures sensor. It also seems from our measurements, that this pin affect both of the ADC channels A0 and A1 in terms of memory from last sample of the charge capacitor. We do have some serial resistors on other high speed ADC inputs to slow down high frequency ringing, but it seems that even 100 ohm is a high impedance when it comes to charging of the sample capacitor. Question: is it possible to have a more detailed description of the actaul sequence that the capacitor will see ?

Forum Post: RE: MSP430FR6047: EVM430-FR6047 (i.e. MSP430FR6047) Ultrasonic Sensing Evaluation Module not working properly.
Hello, 1) I checked the hardware connection...its good. Where on the EVM board I can connect the oscilloscope to see the input and output signals? 2) I adjusted / varied "Gap between pulse start and ADC capture (us) and Gain values" but it didn't work 3) Is the EVM430-FR6047 only applicable with the transducers contacted with water ? All demo cases, online examples shows audiowell pipe only. Does this EVM works with the clamp on (non intrusive / not submerged) sensors as shown in my case? Thanks.

Akshay, I recommend you download the latest version of C2000ware from the TI website and try out the examples there. I urge you to download my app.note SPRA876 and take look at my Debug Checklist (section 3.3). Specifically, please look at the first bullet in 3.3.3 Hardware Debug Tips

Forum Post: CCS/LAUNCHXL-F28379D: I configured DACB Module to produce the output at J7, pin-70. I am not getting any output across pin 70.

Yoshita-san, The current value is fixed for the F2837xD/F2837xS/F2807x devices. If this bit field is supported on a different device(like F28004x) then the bits could have different meanings. However, the PARTNO bitfield in the PARTIDH register(offset 0xA) would tell the FW the family the device belongs to to limit that scope. Best, Matthew
