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...
I'm working on an application that runs on the STM32F030R8, and I'm prototyping using the ST-Nucleo-F030R8 board with built-in ST-LINK, and IAR Embedded Workbench.One of the required features of my application is to jump into the System Memory bootlo...
Hello community,i got the STSW-STM32059 running on a STM3210C eval with truestudio. Now i want to port it to my own PCB, where i use a STM32107RC and the 88E6161 Switch as a PHY. The PHY uses port 5, in 100 full duplex MII mode.Until now i got the c...
Hello everybody !I am working with usb bulk use libusbwin32 and hardware stm32f103vet6. I use multi endpoint EP1_IN, EP1_OUT, EP2_IN, EP2_OUT, EP3_IN, EP3_OUT, EP4_IN, EP4_OUT. But EP4_IN and EP4_OUT do not work, other endpoint working ok. Please he...
When debugging, and when stopped at a breakpoint, does DMA or any interrupt driven process continue? If no, then debugging an incoming serial data stream (for example), can only be done after the stream is completed, otherwise you will miss character...
I'm trying to have the HRTIM master timer trigger an injected conversion of ADC3 on the STM32H753.I'm calling HAL_ADCEx_InjectedConfigChannel() with .ExternalTrigInjecConv = ADC_EXTERNALTRIGINJEC_HR1_ADCTRG2. This call halts in an assert_param() that...
This is the firmware I'm using: STM32Cube_FW_L0_V1.11.0 I'm using the Nucleo-L073RZ board and example. The RTC_LSI example does not work. The LED goes blank after pressing the user button. The Readme says this indicates some kind of error. I ca...
Hello,I would like to know if it's possible to write from RAM to FLASH using a DMA.I tried to configure a DMA as memtomem, using the HAL_DMA_Start function but it doesn't work.Is it doable ?Thank you.François
Using the HAL drivers, it seems that every communications routine (I2C, USART, SPI) has to know exactly how many characters to send, and exactly how many to receive. Now for sending, that's never a problem. For reception, that's been a constant pro...
Hello All,I need to read 4 ADC values with period of 1 Khz in interrupt mode.After reading various post I found out that DMA will be used but I want to read multiple value periodically so should i use ADC injected conversion mode and setNo. of conver...
Hi,I want to play MP3 files that are located in an external flash.Do I need to load the files to RAM for playing them, or can I play them directly from flash?I'm asking because I might not have enough RAM for loading the whole file all at once.Thanks...
