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...

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...
