Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
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...
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...
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...
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...
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...
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 ...
Is there anybody, how has this file for sharing with me? Thanks Joachim
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...
