Single Channel ADC with DMA giving garbage results and values that are larger than 4096
Hi guys, I'm looking to implement ADC and DMA with HAL on a F767. I want the ADC to be always converting and storing to memory via DMA until it reaches the buffer limit of 320 and then I want to go to a conversion complete callback function. ADC seem...
STM32F405 RX0 Interrupt won't activate, wrong filter configuration?
Hi, I am trying to receive CAN message on a F405, but the Rx interrupt doesn't trigger. Sending works fine however.I am also in doubt about the CAN1_RX0_IRQHandlerbecause I can't find any documentation when it is triggered, the HAL manual only refers...
Resolved! stm32f429 hardware iic
Hello!Hello everyone, recently there is a need to use stm32f429 hardware I2C as a slave, debugging a few days without normal communication, want to find a demo referencethanks
Having trouble using DMA to store ADC data in a Timer driven ADC sampling sequence.
Description:I'm running Timer 3 to produce a continuous PWM output on Channel 1.I'm also running Timer 1 in slave mode to Timer 3, in PWM one shot mode with the Repetition Counter set to 5 and the Update Event Interrupt enabled.This causes Timer 1 to...
Looking for a MCU with SPI interface for 24 channel LED driver only.
I am planning to use LED2472GQTR 24 channel LED driver for a project but MCU used in the EVK is STM32F103C6T6 which is a 32 bit MCU. My application is only driving LEDs nothing more. Any simple MCU with SPI interface around 20 to 28 pin count can be ...
Resolved! WWDG watchdog resets system when being refreshed
--------EDIT: I added a minimal example project, 2 posts below.--------Using the WWDG on STM32L07, because I need the EWI interrupt it offers to prevent the reset in certain situatons.(Edit: orig. config code + some obsolete explanation removed. The ...
STM32H742VG HardFault()
Dear comrades!I have encountered a problem while debuging my STM32H742VG project.I am falling into HardFault just after system init and do not know any reason why it is happening. I am starting my MCU with HSI clock and debugign with a STLink v2 debu...
Cortex M4 core cannot control some peripherals on default settings of STM32H747I-DISCO board
I've just bought a STM32H747I-DISCO board and trying to blink the leds on the board (LED1 to LED4). However, when I assign these leds to CM4 core, they won't light when I use default peripheral settings of this board. CM7 core can do this without pro...
ADC And LPTIM in STM32L4
Hello! I once asked a question about ADC:("adc-functionality-in-stm32f1-stm32l15x-series")Since then, the ADC has gotten much,much better, thank you!There are even versions with 16-bit. But there is still one serious problem. This is a built-in refer...
