Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
In specific circunstances (power available, ...) I want to put the MCU in STOP2 mode. That decision is taken on a FreeRTOS task. I've tried some approaches but the MCU didn't stop at all. Is there any example available using FreeRTOS? The code I'm us...
Hello. I have STM3H723ZG Nucleo, by pulling boot pin high and providing reset condition, Nucleo stays in system bootloader mode. With Slave select low, I am send sync byte ( 0x5A) connections made over SPI3 port of STM32H7 controller form my Host con...
I was seeking option to run application without debug via UART, but dont found it yet. Can i download my FW to mcu from IDE without second program?
