Interface and connectivity ICs

1. When using the SD interface of stid135 demodulation chip, we found that MCLK output driver is insufficient. We connect the data line of the SD and MCLK directly to the IO of the FPGA, and the FPGA grabs it online, so we can't get it? Can you solve this

How to switch between Low power modes of a BLUENRG2-M2 BLE module ?

I am using BLUENRG-M2 module as a Network Processor (Controller) and an STM32L4 MCU as a host. I want to make the device connectable via Bluetooth during a limited time (e.g 30 seconds) then put the Controller to SLEEP mode (e.g 30 seconds) to save e...

STUSB4700 GUI offline

The STUSB4700 GUI (STSW-STUSB001 v3.23) requires to be connected to the STM32 Nucleo board + STUSB4700 to be able to start.So if you don’t have a Nucleo board, or if you didn’t wired the I2C interface of STUSB4700 to a Nucleo board, then you cannot u...

How to connect STUSB4700/4710 GPIO pins to a DC-DC feedback path

I'm currently designing a source solution for PD up to 20V 5A. I have the STEVAL-ISC004V1 board for the STUSB4710 and noticed in the schematic that the feedback ladder is connected directly to the GPIO pins on the STUSB4710. The ISC003V1 board howeve...

How to transfer data through ble and get acknowledgment from the receiver (Mobile APP) using BLE - Chat example?

I am using bluenrg2 ble- chat example.my requirement is to transfer data through ble and receive back a response data.Is it is possible using BLE-chat example? BLE received data from the mobile app.To transmit data from ble to the APP,what are the ch...

BLUENRG232 i2c communication with eeprom

How can i assign addresses in EEPROM code of BlueNRG 232 for different vaiables location.As in the sample code bluenrg232 only device address is used not the register address where we will save varaible values memory.function taken from sample i2c ...

Snaphat M4T32-BR12SH6 - expected battery life is lower than 10 years

I'm using the snaphat M4T32-BR12SH6 (battery + crystal) with RTC M41T94.The battery life is short, after less than 1 year, the battery voltage is lower than 2.5 V and the RTC does not work well.And according to the datasheet, the minimum expected lif...

How to port en.fp-ind-predmnt1 (STEVAL-IDP005V1) code to other MCU?

Hi,I would like to know is there any way to port the STEVAL-IDP005V1 code to other STM32F469 controller. I know it is not possible directly inside STM32CubeIDE? any suggestions?The existing micro is not cheap and BGA is very complicate.Thanks.Naveen
