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...
Hello,I am using the Nucleo U575ZI-Q board. I need to use GPDMA synchronized with a timer to set multiple GPIO pins synchronously, perform SPI transmission, and configure PWM periods.I have found a working combination: software request + trigger TRGO...
Hi,first foray into STM32 with a Nucleo-F7222ZE.Using CubeMX I have set up Timer1 to generate PWM. I can get outputs OC1, OC2, OC3 etc, but I cannot get the complementary outputs OC1N, OC2N, OC3N to operate. I feel like I'm missing something, like de...
I am trying to configure a single microphone with a pulse-density modulation (PDM) output on my microcontroller (STM32U575ZIT). It's a CMM-4030DT-261280-TR MEMS microphone.But I can't seem to figure out the basics. The SAI settings mention "Frame Len...
Hi All ,Am imported a example project in stm32cube and i tried to build am getting error as Description Resource Path Location Typenon constant or forward reference address expression for section .ARM.extab LTDC_Paint line 90, external location: c:\...
Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebu...
Hi,I'm getting info on playing mp3 files with my custom Nucleo-U5A9 (originally a NUcleo-U575, I replaced the MCU and added xtal). I'll be using the audio codec TLV320AIC3110 with I2C and SAI from the U5A9. I'll be using ThreadX, FileX an a uSD card....
Hello ST, I am having some trouble generating two PWM signals for a push pull converter. Ideally I would like the PWM outputs to look like this, I would like the PWM frequency to be 100kHz and a duty cycle range of 0% to 50%. I have connected the p...
Hello,In the STM32CubeC0 v1.4.0, when I enable the BYPSHAD bit in the CR register and later try to deinit the device, I get an ERROR. It does not happen if I disable it before deinitialising. Should I disable it by hand, or is it a mistake and should...
Hopefully this is not a dumb question...I am referencing the example code here:https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Applications/OpenBootloaderI see the entry point for the the open bootloader app (ap...
Hi,We are building an IoT device, using STM32L476RET6 as main core. It communicates with an LPWAN modem with AT-commands via UART. We have redirected UART2 into external pins for "serial output" into Nucleo RX pins.During testing, we noticed initiall...
