Hi.I'm working on a project with a STM32F722 and a microSD card. I'm using HAL_SD & FatFS.I want to modify the CSD of the SD card to set the "temporary write protect" bit to 1, to protect the card from accidental writes.It is my understanding you can...
Hello. I need STM with external Vref 3V. But I don't need so much pins like 100pins in ST where we have special pin Vref. Could I use VDDA/Vref pin in STM32F103RC according to drawing belloow? I wanna connect precision voltage reference to VDDA on 3...
Does LSE have any power-saving advantages over LSI when the RTC is used to periodically wake up from low-power modes? Or does it just provide better accuracy for the RTC? For example, let's say you only use the RTC to wake up from stop mode, but neve...
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
