we are planning to use STM32G0 for our next generation design with its USB port, two application is considered:Use it as VCP, the signal from PC is +5 Volt, but the MCU is +3.3 Volt, can the USB port DP/DM pin directly connect to MCU pins? or require...
Hello,This is nur. I need your help. I am working on STM32F769 phy chip , RMII interface. Once I apply power the stm chip then Ethernet cable clicked , there is no connection. if Ethernet cable does not click into place before power is applied to the...
My SysClock is 200 MHz, AHB Prescaler=1.I want to slow down some timer to filter glitches from external input.But when APB2 peripheral clock is set lower than 50 MHzthe Ethernet DMA does not send any data: no ARP, UDP or TCP.Even when ABP2 timer cloc...
Hello everyone,I'm running a webserver on a STM32H7. Code was generated with CubeIDE 1.5.0, using LwIP V2.1.2 and the Firmware-Package V1.8.0. So far, I had no problems receiving or transmitting smaller files, in the x-xx kB range from the MCU to a c...
There are eSIM and Mirco_SIM in the Modem board, but it keep report: CST_modem_sim_init : Can't find sim on current slot. Increment sim slot. CST_modem_sim_init : No more sim slot, no SIM found. Retry... Any suggestion?
So this question arises because the jumpers 3 and 6 of the board switch between either Audio or Ethernet, and I'm not sure in what capacity they're mutually exclusive or not.As an example imagine an application for audio streaming over Ethernet:can I...
The Acquired PDM signal is from VM3000 mic and PDM2PCM conversion using stm32f745?could the acquired values be played as loopback to verify whether the acquired sound is in audible frequency to human ears? How could this be validated? all suggestions...
Hi,How are you all doing?To our application we integrated ST cellular stack to work with QUECTEL Modem M66 and all required features are working expected.Now we decided to integrate lwIP stack from ST and use PPP protocol.I made the initial settings ...
