Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
When I call the tx_event_flags_create() function, the code returns an error at the following line: else if (event_control_block_size != (sizeof(TX_EVENT_FLAGS_GROUP))) { /* Event flags group pointer is invalid, return appropriate error c...
I am trying to setup a local MQTT over a local network with port 1883 and B-U585I-IOT02A using the Nx_MQTT_Client example project. I have followed the steps in :https://community.st.com/t5/stm32-mcus-embedded-software/how-to-connect-stm32u5-b-u585iot...
In continuation of debugging the Ethernet ping test (from this thread) @Andrew Neil @bouazizm Main issue:When debugging the project, everything works well and i am able to ping the MCUWhen flashing the project, the ping test failsHere are the detail...
HiI am in the need to have USB working on the STM32U5G9DK2 board, however I specially do not need ThreadX, so I will configuring USBX in standalone mode. And I do not need to be using UART to complement my sample code as a lot of the sample codes fou...
Hi everyone,I’m trying to chain two timers on an STM32U585 so that:TIM1 generates a PWM on PA8 at 125 Hz (2 ms high / 6 ms low).TIM8 acts as a 20 µs sampler: it should reset and start counting at the falling edge of the TIM1 PWM, then fire its Update...
Hello,I have got STM32U5G-DK2 and i downloaded the example repository for the same. I build the example (Ux_Device_CDC_ACM) at the original location in Repository folder by opening it in STM32CubeIDE. It builds successfully but when I copy the same e...
Hello,I am working on the STM32H743BIT6 ethernet communication. I am using the external PHY DP83TC814RRHARQ1 for my requirement. I am configuring in CubeMX as USER_PHY under platform settings of LwIP. How can i communicate via external PHY.? Does con...
Hello,in all examples for the STM32H7S78-DK - including the TouchGFX applications - the frequency for the external APS256XXN-OBR-BG PSRAM is set to 200 MHz:extmem_list_config[1].PsramObject.psram_public.FreqMax = 200 * 1000000u; But in the datasheet ...
Hi, I tried adding APPKEY on the flash to read from bootloader to find if valid application there or not. I added as below in scatter file :EXCLUDE app_key.oAPPKEY 0x08043FF8 FIXED { ; 0x08013FF0 = last 16 bytes of 64KB appapp_key.o (.app_key)} and i...
Hello, I have a STM32U585CIUA and generate a PWM with 125Hz 2ms high and 6ms low phase on TIM1 on PA2.I would like to start another PWM with TIM2 50Khz 1us high and 19us low on the falling edge of PA2, which is then stopped after 200 cycles.In all my...
