STM32 MCUs Products

Hello, I'm using hal_delay in my code. The part where I used hal_delay to take a waveform using an oscilloscope is a little strange. Can Hal_delay cause waveform problems?

Looking for STM mcu with less than 10uA/MHz current consumption that include Bluetooth co-processor. Is their anything available?

I can't seem to find any ST MCU with less than 17uA/MHz. Is there anything closer to 10uA/MHz ?Also, does ST offer MCU with a bluetooth co-processor?

Hi All! From where I can download ARM assembler?

I am trying to read several adc channels on the stm32 microcontroller, but it won't let me, it only reads the first one.

I am trying to read several adc channels on the stm32 microcontroller, but it won't let me, it only reads the first one. I have seen in the registers that when changing channel what it does is that it sets the selected channel bit to 1 and does not m...

DAC Outputs Not Equal

Hello,I use the internal DAC of the processor. Even the initial value of the DACs are equal, I got 1V out from the first output of the DAC, and 2V output from the other DAC output. Why is that happen?/* USER CODE BEGIN PV */   // DAC Settings   float...

CANFD multiple senders - Tx Issues

I've been doing the majority of my FDCAN development with 1 or 2 nodes.Recently, I have expanded my "network" to 7 nodes. 4 of these nodes send data at the same time.(I mean, 1 second intervals from power up. They are all powered simultaneously)With ...

STM32F427 - No SPI4 Communication

Currently, I am seeing no signals on the SCLK and MISO/MOSI lines on the SPI4 lines from a STM32F427 chip to a SPI flash during an attempted read/write. At the moment, I've done the following:Enable GPIO clock (HB1) and SPI clock (PB2)Configure CS:pi...
