Hello everyone,I'm trying to use a KSZ8863 to monitor ethernet traffic. the KSZ8863 is connected to a STM32F767 via RMII.Im using the STMcubeIDE lwIP stack.I have no problem getting a ip-adress and ping the STM32. Also the SMI interface to the KSZ se...
Hello,Iam using HCF4010 for my project. Can i use this as CMOS to TTL converter?Also for high speed switching or for high speed signal is there any issue for using the same ic(Please find the attached image,4 GPIO & 2 spi lines were used)
I am using the Discovery IoT Node kit with (mostly) base software. It looks like it makes a connection OK, and the SendEventAsync accepts the messages it wants to send, but I don't see any data in azure iot central.I checked using a virtual device o...
I suppose there are some mistake in Blenrg CodeStatement: * @arg FIFO_LEV_1_64: interrupt when Tx FIFO becomes <= 1/64 full = 1 ... at the line 440 of blueNRG1_uart.c is misleading. In accordance to datesheet instead of "full" should be "empty". In t...
Hello,Iam using HCF4010 for my project. I tied both vcc and vdd into 5V. The 6 input to the ic is connected to an esp32 chip(3.3V). Is there any problem while using like this? Is it take more current from the inupt side? As per the above connection...
Hi there,Seeking lowest possible energy, what is the difference between the two operation ?Do the configuration remain on the peripheral if I cut the clock ? (then restore it before transacting with the periph)Side question: What to avoid in order to...
Hi,The BlueNRG-2 describes compatibility with the 5.0 spec. but I've been unable to find specific mention of the longer range via lower bit rate 500kbps or 125kbps and Forward Error Correction (FEC).Is this long range mode supported and if so can you...
Hello, in our project we use SPBTLE-RF0 modules. Unfortunately we did not pass RX test according to EN300328.On the module the newest sw is running. The module is located in the directmode and is controlled via hci. I have not found any radio report ...
I tried 3 different import options, but STM32CubeIDE disables the build icon, and there is no .project file. It appears that the firmware was created in a different development environment, but all the documentation says nothing about it.
Hi,I'm starting to play around with ST BLE.I'm using X-NUCLEO-IDB05A1 on NUCLEO-F401RE.I've just followed the "Getting started" https://www.youtube.com/watch?v=AIJA4yRxuP4 I've drag .bin over the icon: NUCLEO_F401RE (C:\Users\andre\Documents\BlueNRG ...
