I'm developing a very power-saving product. The STM32L4 is a really great product for our application ! Usually I run the STM32L4 VDD at 1.8V. Operate at 3.3V only when end user configures it via USB. The problem is that I want to switch the VDD volt...
I am trying to port an existing design that did not use the external memory loader into a version where I can use the external memory loader so that I can add additional code.I watched the videos and read the materials and have successfully made the ...
Hello,We are using the STM32H745 dual-core MCU for a mostly-analog sensor project. The M4 core is running at 240 MHz and generating a signal on the fly that is passed to the DAC via a DMA stream in circular buffer mode. This part works great.The si...
Hello All, We have a problem with crosstalk between two neighboring ADC pins. On a STM32L496, on PA7 and PC4, two independent single-ended ADC channels are configured in the most simplified way possible. Connected pins and ADC config: Method/Function...
Need advice selecting an STM32 device (package should be LQFP32).Want to replace an STM32L051 (LQFP32). Want similar footprint. The replacement shall use less power or equal. Must have possibility to run on an external high speed oscillator (HSE). Th...
Greetings,I have a B-U585I-IOT02A. I am trying to connect the board to the STM32CubeProgrammer using the USB-C. I placed the BOOT0 jumper to 1. And when I go to USB, the Port shows "No DFU detected". Any clue what steps I need to take in order to mak...
Under what circumstances is the 32.768kHz clock signal present on the PC15-OSCX_OUT pin of the STM32C071 product?
Hello,We are using the STM32H573 in a new project. We have designed a custom board using the 64-pin LQFP package.The MCU connects to a ethernet PHY using RMII interface.Our product has to meet strict radiated emissions levels that are 7dB lower that ...
I've spent some time recently trying to prototype a small project based on the STM32H503 which would need to have the ADC and DAC running simultaneously with multiple channels of analog I/O via DMA. I was able to get this all coded up but discovered ...
STM32L432KBU6 L432 chip, spi3, 16bit mode, 20M baud rate, spi output sclk is 16 cycles when it is powered on again after working for a period of time. Sometimes 15 cycles, sometimes 17 cycles, sometimes 16 cycles are output again. This will help conf...
