Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Update: Using a USB analyzer shows that we get a one bit shift in the data when we have problems writing to a USB flash drive. It can be the CRC that is bit shifted, and other times it can be the data values that are bit shifted. This sounds like an ...
I am trying to porting Zephyr to my own board which is designed on stm32f429i_disc1.So I copy the folder zephyr\boards\arm\stm32f429i_disc1 for my porting.A problem comes up when I am configuring the IO pin for I2C2.In stm32f429i_disc1.dts, the i2c...
Hello,several years ago, we built an audio device based on an STM32 MCU with a cortex M4 core. The firmware is highly optimized for the audio processing and it uses few 3rd party DSP libraries.Recently, we had an urgent request from one of our major ...
I am wondering which is a faster way to stop PWM generation. Would it be through HAL_TIM_PWM_Stop or by setting __HAL_TIM_SET_COMPARE to zero? I'm getting SPI commands via a raspberry pi and then based on those values, I start or stop the motors. The...
Hi, I'm trying to L432KC to play WAV file using Adafruit MAX98357 I2S Class-D Mono Amp, SAI+DMA and I2S protocol.The code is running as one the tasks of FreeRTOS, but getting rid of RTOS doesn't help.WAV file is read from SD card, and I've already be...
Hello Team,We are trying to validate OV2640 2 MP USB camera over STM32F429ZI Development which we have. Our Main Project aim is as per below1) Capture Image or Video Streaming with maximum 2 MP like OV2640 USB Camera2) Transfer over WiFiSo, Can anyon...
Hi,I've looked through the HAL code, and it looks like the DMA path blocks waiting for a ack response from the slave. Am I right in thinking that if i'm using the HAL to communicate with i2c then I will still be bottleknecked by the maximum speed of ...
Dear Support, i wold like to distinguish in the linker script, the DCTRAM from the other RAM in order to explicitly allocate some buffer, in my code, in the DCTRAM. So i changed the STM32F765VGTx_FLASH.ld from this (original version form CubeMX):/...
Hey guys.Im using cubemx for i2c initiallization and i have a problem while using this HAL_I2C_Mem_Read_DMA function.When i call it in while(1) it works one time and after that it returns error or busy. while (1) { HAL_Delay(1000); HAL_I2C_Mem...
I need to modify ongoing the ic polarity of a timer input capture channel. I could act by changingchange TIM_CCER_CC1P directly, but i want to know if there is any other solution using HAL libraries. I'm using an STM32G0 mcThank you in advance.Enric...
