I am trying to communicate STM32F072RB with BQ40Z80 (which is connected to the battery) via SMBUS protocol. I am not able to read the data from the battery. According to SMBUS protocol to perform a read operation.Master (STM32) must transmit the targ...
I am trying to do a blink example for testing using built-in LED on bluepill. Unlike regular delay and period interrupts, i want to try a custom-duty blink, in which i want 3s on and 2s off, a total of 5s period.in main: HAL_TIM_Base_Start_IT(&htim1)...
(edited this post from previous panic language; still think its good to keep it around - and a suggestion: there should be a tag/category for "Community Website")Well, since ST asked me to register for downloading software, I thought I'd be honest, a...
Hello,I am using STM32L4S9 and the datasheet mentions the LSI is 32khz. Is this 32000hz or 32768hz? Best,Jeff
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...
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...
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
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...
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 ...
--------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 ...
