I am using STM32F469BIT6 on a custom PCB with IS42S16400J-7TLI external 8Mb SDRAM. On my previous board, I was using STM32F429ZIT6 with the same SDRAM (these mcu&sdram selected because they were used in STM32F429-DISCO) I was able to write/read data ...
I am using STM32 with the following peripherals:TIM7 for frequency generationADC with DMADAC with DMATIM Interrupt (TIM_IT)My setup:Clock: 150 MHzPrescaler (PSC:( 3-1Auto-reload register (ARR:( 13-1128 samples for DAC to generate a 30 kHz signalWhen ...
Dear ST Community,I have been working on the firmware which contains the AT commands modem, Winbond flash memory. After some time I have relised the microcontroller is automatically getting restarted/. I had doubt on the hardware then we have redeve...
Dear Sir.I am using a board equipped with STM32U585 , The main clock is 32.768 khzsee included pic.PA8 is configured to drive LSE 32KHZ using the command__HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_HIGH);PA8 is fed to ECG MAX30001.On some boards MAX30001 r...
Hello,I have a STM32L152RE and I use PA1 (Pin type is FT 5v tolerant) as ADC_IN1. Vdd is 3.3V and the voltage on PA1 usually is around 5V and sometimes it drops to 2.5V ( when I need to take the measure). Several comments on various blo...
Hi, I have a STM32G474 connected to a Quectel LTE module via a uart4 and a GPIO pin.Under normal conditions is it possible for the CPU to boot from flash and when the quectel changes the level of the gpio pin of the STm32, the CPU jump to boot from u...
I have created my first PCB with a STM32C011F6P6 on it, but I am not able to measure a GPIO I set high from my testpoint.I am setting PB6 high the following way:I flashed the code to the MCU via the cube ide and it told me that everything went fine.T...
The link on the bottom of page 158 is bad.There is no SBF flag in PWR_CR3, actually it is in PWR_SR1.
I have made a PCB with the STM32C011F6P6 on it and am trying to program it via an ST-LinkV2. While trying it out yesterday, it connected just fine with the cube programmer. Now I am trying to do the same thing again, but both the cube programmer and ...
The Reference Manual for STM32U0 series MCUs, RM0503 Rev2, specifies, in table 2 on page 57, that SRAM starts at 0x2000 0000 and ends at 0x2002 9FFF. This is a contiguous region with a size of 168KB. However, the Size column shows 40KB. This docum...
