Forum Post: RE: TSW1400EVM: MATLAB api error while using the radar studio
Hi Anand, Thanks for your response. I tried the DFP 00.09.01.06 version and the problem is the same. The radarStudio could not find the postproc and the error is the same as the original post. Also I...

Hello BMS, I apologized for late response. I'm not sure whether you have solved the issue or not. It is not easy to check your simple schematic, even the buffer amplifier PN is not shown above. I...

View ArticleForum Post: RE: DAC39J84EVM: Question about choice of analog output transformers
Hi Jim, Thank you! Those are what I plan to do. So as you implied, DAC3XJ8X does convert low-pass signals from digital to analog, doesn't it? Is there a lower limit on that; i.e. can it provide, say, a...

Hello Sai If you are still having issues with differing gain on A and B channels and cannot find the cause then there is some other problem with the board. In that case I authorize you to return it for...

Hi Khoi, Do you have a good ground connection between the ADS1256 and the ESP32? This behavior could be explained by a loss of communication, which may result if the MCU and ADC grounds drift apart....

Hi Alex Thanks for replying. Yes, you're right, I meant to say that it outputs only 0's (it does that it does that while I'm querying the registers, but regular data output is also 0s). I've turned the...

Hi Jan, I checked with our test team and the test program was updated in the time between the two lots were made, but these were minor changes and the performance did not change between them. I assume...

Thanks Paul, I need to take back the statement that we read device ID A0 on the earlier devices, it was A1 there as well (however, we still can distinguish the devices by the marking on the package)...

Hello Bob, right now i am using the default register settings at startup which means i dont write into the registers. I just power up the ADS1248 and then send 24 SCKL'S to get the data. I also tried...

Hi Mark, As you can see from TI website link (please see the user's guide), for our AFE LVDS output device, we only use TSW1400EVM for data capture. Because TSW1400 can capture many data for many...

Nathan, When debugging digital communications, the first thing I think you should do is get an oscilloscope or an logic analyzer and look at the lines between the device and the microcontroller. For...
View ArticleForum Post: RE: ADS1299: ADS1299 interference with other SPI slave
If I had to guess there's something in the ESP32 that's holding the line low, but it could be one of the other slaves. Do you have another port you can open on the pic32 to try different combinations...

Hi, One thing that may affect the output of the PGA is the input range of the PGA itself. The PGA is constructed like the input of an instrumentation amplifier. First, note that if the supply is...

Hi Eduardo, How is the 3.7V (battery) voltage referenced to the ADC, it is floating or does it connect to the ADC ground? I would recommend trying to measure the bridge ratiometically. By this I mean,...

Hi user5922913, A couple of things regarding the code. First, you must delay before communicating to the ADS1248 after a RESET command is issued. See Figure 80 on page 46 of the datasheet. This command...
