First of all, I am not using CUBE IDE, this is a bare metal.Second: STM32H523. ADC (continuous mode; DMA). ADC is configured on PA0 (i.e. INP1, single-ended), GPIO configuration is analog mode.On the pin I can probe (oscilloscope) my signal (correct ...
In the RM0456, the LPUART has a block diagram (67.4.1) with a register called LPUART_ RTOR but there is no documentation about this register. For USART, this register is related to Receiver timeout interrupt but this feature is not available for LPUA...
I am using the STM32L433RCT6 and need to assign a GPIO pin as an external interrupt, which will be used to wake and shutdown the MCU (shutdown must use minimal power).However, I am not sure if I have to use a specific GPIO pin, or if I can use any GP...
Dear,We would on the STM32H7B0RBTx connecting 2 external QSPI RAM of APS6404L-3SQN-SN.Therefore we will use the 2 QSPI RAM chips in Multiplex mode, but we have only 1 NCS pin that we can configure.When we look in the application note AN5050 on page 2...
Hi, Since there's a huge market for microcontrollers on boards such as the Arduino, like the ATMega and ATTiny, which are available in 20- or 40-pin DIPs, I was wondering if ST competes (could be with the 32bit or 8bit line) with those somehow. If so...
Hello，I want to use the PB6 pin as an external interrupt input. When the PB6 pin is triggered, the program enters the low-power stop mode from the normal operation mode. When it is triggered again, the program enters the normal operation mode from th...
Hi STM Community,I am using a custom board based on the STM32F407VGT6 MCU. Currently, I’m not getting accurate RTC time when using the internal LSI clock (the drift is too high for my application). So I’ve decided to use an external 32.768 kHz crysta...
Hai. Currently we are working in a project, for that we require AEC Q-100 Products. In that we need STM32F405VGT6 in Automotive Grade. AEC Q-100
This is driving me crazy, whay timers on STM32 are so complicated and no normal information / datasheets etc, how to use.Timer2 is working (external clock), Timer interrupt (TIM_IT_UPDATE) also working, but not capture interrupt. And signal is also p...
Moved from this thread. What is the maximum amount of time required after bringing nRST high for a Pattern 11 MCU to determine that flash is blank, recognize that BOOT0 is high, and enter the ROM bootloader? I suspect we may have a timing issue, in ...
