i am trying to make a bootloader for a stm32f030k6t6, i was reading the AN4325 application note, from what i understood that i can only have a USART bootloader on pins PA14/PA15 or PA9/PA10, and i have a bluetooth connected on the uart1 serial which ...
Hi,I took an example code that implements USBD AUDIO device and ported it to the STM32F411E-Discovery board. Now I can play music from my computer using this board connected to the audio jack.This example works when I set the sample frequency to 4800...
Dear all,I have established ethernet UDP connection using the following tutorial https://controllerstech.com/stm32-ethernet-3-udp-client/And i'm able to transmit and receive packets.But the problem is when my receive packet contains zero all the data...
I tried activating the sim from the module P-L496G-CELL01 as the link was redirecting to the home and another link was redirecting to the second version of the module. Is there a way to activate the sim? Is there a way to upgrade the first hardware f...
Dear all,I have established ethernet communication successfully using STM32H757i-eval board following this link : https://controllerstech.com/stm32-ethernet-3-udp-client/ But I do not understand how the MX_LWIP_PROCESS and udp_recv work??And where is...
Hi,Am I allowed to call the USBPD_PE_Request_CtrlMessage(), USBPD_PE_Request_HardReset(), USBPD_CAD_PortEnable() and others from different threads?I want to request data role swap, power role swap and hard resets from my interface thread.Thanks!BR, C...
Hi, I am currently working on the STM32H743 and i'm trying to bring data from SPI6 to a buffer in D2. As I have a lot of data to read i would like to use the DMA in order to transfer data without using the cpu. I don't understand whether I can use th...
