Interface and connectivity ICs

STMPE811 TSC IC, I can I2C READ perfectly, all 100 registers, but I2C WRITE never. I have tried used HAL_I2C_Master_Transmit() and HAL_I2C_Mem_Write() and neither work. Pulling hair out, nothing left :) There must be a secret...

Could you advise us whether CMOS camera has electrical saturation in switched off mode due to flashlight exposure right before dim fluorescence signal acquisition?

I am a researcher from Macquarie University. We're interested in using your CMOS cameras in-built in a smartphone for research and business purposes. We're trying to detect fluorescent signal in millisecond time frame right after a flashlight.Looking...

Run BlueNRG-MS with BlueNRG GUI and STLINK-V3SET

Hello,I bought an STEVAL-IDB005V1D board with an BlueNRG-MS chip. Is it possible to control the chip with BlueNRG GUI through the SPI of the STLINK-V3SET ?I could do it for a BlueNRG-M2 board through UART, but it does not seem to work with the BlueNR...

Is it possible to use S2LP transceiver IC with pulse interval encoding (PIE) other than Manchester and NRZ encoding schemes mentioned in the datasheet?

ble scanner GAP_CENTRAL_ROLE to receive Beacon data but data length is zero?

I trying to read iBeacon adv data for uuid, major and minor. But I notice I only able to get the address. I tried to print out the AD data, but it always tell me its empty when iBeacon is detected. Please help./***************************************...

No Response on SPI from BlueNRG-MS. How do I know where the problem is ?

Hello everyone,I've designed a PCB With a STM32H7 which is supposed to control a BlueNRG-MS. The design is the similar to the Figure 6 of the component datasheet: https://www.st.com/resource/en/datasheet/bluenrg-ms.pdfI didn't put XTAL1 since it's op...

Setting up STUSB4500 sink for 12V,5 A

We are using the STUSB4500 PD chip in one of our applications. The requirement is to set the Power delivery to 12 V and 5A for the sink. I have been referring the driver code provided by ST to program our microcontroller. To set PDO to 12 V and 5 A, ...

[STUSB4500] What is the decision algorithm for source PDOs that are not fixed supply type?

Hi,There are three type of source PDOs:Fixed SupplyVariable Supply (non-Battery)BatteryDocuments gave examples for the decision algorithm for Fixed Supply type source PDOs. But for Variable Supply (non-Battery) and Battery type of source PDOs, the vo...

BLUENRG-Tile (Social Distancing and Contact Tracing SDK)

Hi,I have bought 2 BlueNRG-Tile and would like to try out the application as per link below.https://my.st.com/content/ccc/resource/technical/document/application_note/group1/43/8d/b8/4e/44/91/4b/64/DM00712091/files/DM00712091.pdf/jcr:content/translat...
