Hi Bruce, The device is released, but your company is required to have an NDA with TI in order to access it. If you have an NDA, you can request access through this link: ti.com/secureresources/AMC7904-DESIGN If you need to get an NDA, please contact Luis Brum at l-brum@ti.com to get assistance. Thanks, Erin

Can you tell me how much is stock available? It sounds like we have to purchase this directly from TI.

Forum Post: RE: ADS1261: Responding with All Zeros Part 2
HI Everett Everett, For sure there are timing delays between CS low and SCLK high, check the timing requirements of the ADS1261 datasheet i.e. this is not allowed: Add a delay of one SCLK (200ns for example) between CS low and SCLK high and see if that improves the situation. Do the same on the back end (SCLK low to CS high) It also looks like your LA is still triggering on the rising edge based on the icon you have selected in the top left corner. This needs to trigger on the falling edge (the data looks okay, so your system might be getting the correct data, only the LA is wrong) Also the third and fourth images are showing that CS is high when you are sending SCLKs, which means the ADC is not receiving them. So of course the ADC will not respond. -Bryan

Forum Post: RE: TSC2004: Touch Screen not responding properly.
Hi Aswin, There is not much flexbility with this device to increase sensitivity, which sometimes may lead to using a lighter touch screen panel for a better response. Please try configuring Configuration register 1 (CFR1) which defines the connection test-bit modes and batch delay selection.

Forum Post: ADS131M08: Drivers and support (Linux)
Part Number: ADS131M08 Other Parts Discussed in Thread: ADS131E08 Tool/software: Hello E2E; We are on the verge of committing to this part, but I just noticed that my eyes have played tricks on me. linux/drivers/iio/adc/ti-ads131e08.c does not say: ti-ads131m08. I see now that ads131e08 is a completely different part than ads131m08. I doubt that the driver is compatible. We are on Linux Arm64 with Yocto. Raspberry PI is a Broadcom BCM2711. We want 8 channels @1kHz over SPI. All I see is: hal.h hal.c ads131m0x.h ads131m0x.c Have I missed anything? Seems simple enough. Or have we made the wrong choice? If so, I need to put the brakes on hard, as our schematic is essentially finished. Thank you! Clark

Forum Post: RE: TXB0108: TXB0108 - Open drain pin support
Hi Jack, As per the SCEA054A document, testing was done from A to B configuration. In the A to B configuration, 4K series resistor in B side. That why we facing VOH and VOL issue. But in our case, we are using B to A configuration. As per block diagram, in the configuration 4K series resistor in A side. As per our understanding, Voh and Vol issues will come if we put pull up/pull down in A side. We are putting pullup in B side for open drain. Will it create any issue? Thanks, Jeeveth

Forum Post: ADS7028: Read and Write Issue with ADS7028
Part Number: ADS7028 Tool/software: Hello, We are trying to use ADS7028 sensors for ADC readings in our project. But we are having issues with the communication. In short, we can't seem to write anything to the registers of the ADS7028 and when we read back the register contents of the same register for debugging, the content constantly keeps changing. This can be seen from the attached pictures. In these pictures, a register read command is sent for the SYSTEM STATUS REGISTER. But as it can be seen from the picture, the data received from the ADS7028 changes for each message. Orange: Data from ADS7028 Blue: Chip Select Yellow: SCLK Green: Data from MCU We are really stuck, so any help is appreciated. Thanks, regards.

Forum Post: RE: TSC2013-Q1: Single Touch Configuration
Dear Daveon, Thank you for the detailed configuration settings. I previously implemented the changes to CFR0 and CFR1. As per your suggestion, I have now implemented the CFR2 settings. The system is working much better, However, I am encountering some issues with repeated values and ghosting. Specifically, the screen cursor occasionally moves erratically, displaying ghosting values, and some touch events are repeated intermittently. Here are a few examples TOUCHEVENT - X, Y TOUCHEVENT - 610, 310 TOUCHEVENT - 223, 279 TOUCHEVENT - 608, 313 TOUCHEVENT - 226, 284 TOUCHEVENT - 611, 313 TOUCHEVENT - 219, 281 TOUCHEVENT - 217, 283 - Repeated TOUCHEVENT - 613, 309 TOUCHEVENT - 620, 318 - Repeated TOUCHEVENT - 215, 284 Could you please advise on how to address these issues? Any additional configuration adjustments or troubleshooting steps would be greatly appreciated. Thank you for your assistance. Best regards, Veer

Forum Post: RE: ADS7138-Q1: Abnormal read register value, unable to successfully write register
Hi Joel Meraz, Today, I tried two ways to read AD values based on the reply Method 1: Start reading the device (Figure 8-12) According to the process, the configuration is known, but since many registers have default values that meet the configuration requirements, it is only necessary to first read and confirm whether the relevant registers have default values. If it is the default value, it meets the configuration requirements and only requires CAL=1 to be configured. Then send S+7-bit device address+read flag+A Verification process The host provides the following values for the Conversation Start Frame read on the bus: Assign the LED lights from left to right to the 6 physical buttons numbered 1-6 My question regarding this verification method is: 1. May I ask if the verification process above complies with Device Operation in Manual Mode 2. If yes, does the value read by i2cCSF represent AD value? Why doesn't it correspond well with the measured voltage? Method 2: Read from the Recent-CH0_SB and Recent-CH0.MSB registers. Need to set the STAT3 and CNVST bits to 1 Then I saw the description in the 0x01 register and thought CAL might need to be set to 1. So I separately verified that STAT3=1 CNVST=1、CAL=0， And the results of STAT3=1, CNVST=1, CAL=1. The values read in the morning are as follows: Unfortunately, I didn't take a screenshot of the data captured by the logic analyzer Number the keypad 1-6 from left to right using LED lights However, in the afternoon when I was preparing to reply, I read the following values: Number the keypad 1-6 from left to right using LED lights Now I don't know where the problem lies. 1. Not sure if the value read in the morning is the correct AD value? 2. Why can I read the value in the morning, but later in the afternoon I can only read 1C 0E Regards, Ziming Yi
