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...

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

Is it correct that I need a BLUENRG-M2SA module in order to program a BLUENRG-2 chip?

I have a blueNRG-2 chip on hand, and I am looking to program the chip to have the ability to connect to android devices (for a project). Am I correct in my thinking that I need a BlueNRG-M2SA module in order to achieve my end result?

How to send and receive more than 20 bytes (Default ATT_MTU_SIZE = 23-3) over ble using ST bluenrg LP?

I am using BLE Scanner app to write data to a characteristic in BLE device. I sent 35 bytes of data, but the device receives data 20 bytes per write operation and then receives 15 bytes more. How to receive all the 35 bytes with single write operatio...

BLUENRG-232_SCH_REVA_30JUNE2020

hi,We designed a board using BlueNRG-2 and we uploaded the GPIO demo code available in BlueNRG-2 navigator (to toggle DIO14) to the board using the BlueNRG-ST- Link utility. The board didn't detected with high Frequency(.9MHz-4Mhz) so we changed the ...

getting started with x-nucleo_BNRG2A1 with nucleo-l552ZE-Q

Hi all, I am using X-NUCLEO-BNRG2A1 with NUCLEO-L552ZE-Q board. I have created a project with STM32CubeMx using X-CUBE-BLE-2 SensorDemoBLESensor Application, mapping the pins of the expansion board to my nucleo board as :PA5: SPI1_SCK ==>I s...

Trying to interface an 1 Msps 16 bit adc with a stm32f4 using spi/dma. Is this possible at 1 Msps?

The problem is that the convert/chip-select pin needs to be asserted for about 700ns for the conversion to complete.The NSS signal of the stm32f4 only is asserted a very short time, so that would not do.Maybe use a timer to generate the convert pulse...
