STM32 MCUs Products

Hi, Is there a way to use an J-Link debugger with the STM32 ST-Link Utility? Greetings Eric

In our application,under Power OFF Condition,we will be using static situation of RAM supply of some 20 bytes(LSE is not running at all and no RTC crystal is used)and all other Peripherals will be in the OFF Condition.For this condition we need IDD_VBAT.

Part Number: STM32F091VBPart Family: STM32F091xxQuery Description:From the datasheet of STM32F091VB, the current IDD_VBAT through the VBAT Pin is noted as belowThe data in the above table is given in the condition where LSE and RTC in ON.In our appli...

STM32G4 check if programmed previously

You can't reprogram flash double words on the stm32g4 even if the were programmed to 0xFFFF'FFFF'FFFF'FFFF.Does anyone know if it is possible to check if the 0xFFFF'FFFF'FFFF'FFFF value I read from a specific flash position has previously been progr...

I think I am enabling packet error checking on specific I2C reads from a peripheral device. I do this by setting CR1 bits PEC, POS, and ENPEC, then doing a HAL_I2C_Mem_Read. I get expected results from the register read. Should PEC be zero?

I look at SR2 PEC contents (most significant 8 bits), and they always are zero. Is that normal?

Very Long Reset with NVIC_SystemReset();

Hello, I work on a project using SPI to communicate Data acquired and processed with Motion FX. When an incomming signal is received, i want to reset my STM32 MCU with a software reset. However, when i do so using NVIC_SystemReset(), the spi communic...

How to use IDB05A1 in low power mode with L0 series MCU without DMA.

I am trying to use IDB05A1 BLE module in low power mode with STM32L073RZ MCU. I didn't get any reference for doing it without the DMA.

How to configure two ADC Channels in STM32F413ZH, If I vary any one another channel is varying ?

STM32L452 temperature sensor

I'm using the below to calculate the temperature in STM32L452 CPU:int16_t temperatureC ;// ADC VREF is external 3V3temperature = __HAL_ADC_CALC_TEMPERATURE (3300, ADC_val, ADC_RESOLUTION_12B);For ADC_val = 1360 - then temperatureC is 164 Celsius, whi...
