STM32 MCUs Products

Resolved! Hello Community, I am working with a controller which has FATFS in it. When i am trying to create folder with name as YY-MM-DD it is giving me an error, it is only accepting YYMMDD format, i have to differentiate year, month and day with some symbol,

can somebody tell me, how to do it

ADC+DMA fills all the buffer when calling to HAL_ADC_ConvHalfCpltCallback()

In a stm32f303rb76, I commanded to operate ADC+DMA by setting of the ADC DMA with circular modeThe ADC I activated continuous conversion modeand DMA continuous requestAlso the analog input signal (no scan mode)In the initialization made following com...

TRGO and Repetition counter? STM32L476

I have a prescaler (20), an ARR of (65535) and a Repetition Counter of 3 on a 20MHz clock ....On the scope it all looks good...Question if I set a timer up to be triggered by the Update Event, will the timer being triggered update on the output I see...

Resolved! In RM0394 Rev 4 page 873/1600 field OCM1 is bits 6:4 which I count as 3 bits. But the description shows the settings as 4 bits with 16 choices.

For example: 1000: is Combined PWM Mode, 1111: is Asymmetric PWM Mode 2. How do you fit 4 bits into 3 bit spaces? Bit 7 is used for OC1CE, and Bit 3 is used for OC1PE so there is no space on either end for the extra bit.

Resolved! Transfer complete from GPDMA1 missing for SAI sync slave receiver

I configured SAI1 asBlockA: I2S async slave transmitterBockB: I2S sync slave receivermanaging the data transfers with GPDMA1. The slave transmitter works fine, I get the half transfer and transfer complete interrupts correctly. But for the slave rece...

hi, from where i can download datasheet for this stm32g0b1rbt6 microcontroller only not generalized one

STM32H7B3NIH output PB8 is not working as GPIO, cannot be set high.

I have tried everything I can think of to set PB8 high. This is a custom PCB where PB8 is connected through a 1k resistor to a stepper driver input. With board off, measuring pin to VCC resistance is 105kOhm, measured to GND is 95kOhm, so not directl...

Resolved! The Build Analyzer says my processor STM32L443CC has 64K RAM and 16K RAM2. And I am not using any RAM2. What is RAM2 and how do I use it?

On other processors sometimes there are keywords when defining variables to specify which memory area the variable should be stored in. Or there is a #pragma statement. I have not seen either in the STM32 or the IDE. I am guessing RAM2 might be a goo...

Resolved! Precise delay function on STM32F401CE

I have tried a lot of different things but I can never seem to get it, I am trying to make a semblance of a precise delay function for my controller, I am not using HAL or anything, just writing to registers directly. I tried timers, timer interrupts...

Detecting available UARTs at compile time

Hi,using CubeIDE with CubeMX, is is possible to "check" or "detect", for conditional compiling, which UART ports that are enabled? In the MX-generated USART.C you will find all the handles for the available UARTs but AFAIK, you can't conditional comp...
