STM32 MCUs Products

On the STM32F777 I am trying to determine if there is a readable silicon revision level.

 I realize that I can read the ID Code Register at 0xE0042000, but I am not sure how the silicon revision is indicated for a specific device. Is it readable though the codes on the device itself?

DAC in STM32F4 and STM32F7 poor accuracy

I am trying the DAC in the STM32F4, so far I am using just the HAL_set_value function and I am trying to get a clear output voltage. I am using the STM32F46 nucleo board.I see that the ripple at the output (using the internal amplifier) is far highte...

RTC of stm32l031k6 counting more

I want to use RTC of stm32l031k6. But once I tested it I noticed that it counts 8 seconds more in a minute. I need a precise rtc. Do you have any advise what should I do.Thanks,

PSRAM with 32-bit data bus width?

According to the STM32F4/F7 data sheet FMC controller support 32-bit bus PSRAM. For my application I would like to use this configuration, due to a high bandwidth requirement. However, in the market it seems very difficult to find a PSRAM with 32-bit...

Changing GPIO mode at runtime

I'm trying to change GPIO mode at runtime, i could able to change mode from input to output and vice versa. But once configuring GPIO as EXTI i'm not able to change it to any other mode. and even if i try to change, ISR is getting executed.

After STMCube update to version 4.27.0 HAL RTC driver clear RTC date and time and set it's to default value on MCU power up, STM32F373 series and STM32Cube FW_F3 V1.10.0.

On last version normal rtc init code was so:/* RTC init function */ static void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime; RTC_DateTypeDef sDate; RTC_AlarmTypeDef sAlarm;...

Using TIM1 for get two positive pulses.

Hello.I using uC STM32F030F4P6. I need generate sequence positive pulses with help TIM1. Please see graph in the attachment. The first, must generate one positive puls with weight 1us on the channel 1 after this, must generate pulse with weight 6-16u...

STM32F100 Temperatur Sensor with VDDA = 2.8V

​Hi,I am usign the STM32F100RB with VDDA = 2.8V.However when trying to use the internal temperature sensor I can calculate a slove of approx 2mV/K instead of approx 4.1K from the electrical caracteristics.Is there anything different at 2.8V instead o...

Issue in code uploading for the IC STM32F100ZC.

hello, Iam having a issue in uploading the code to STM32F100ZC, I have attached the schematic of SW interface done. Its showing an error that target is not connected. I have done all the possible connections for BOOT0 and BOOT1 pins.Please h...
