Problem in writing SD card

Hi to all,I am not sure this is the correct forum, but I do not know where to put the question elsewhere.I need to interface with an SD card using SPI interface and I'm experiencing a big issue in write operation (CMD 24) because things quite always ...

Role of System Bank 2 in STM32H7x5

In STM32H7x5 series, the MCU has 2 System Memory banks. Bank 1 is clearly described in reference manual, but not bank 2. My question is:What is the role of bank 2?Can user use bank 2 to flash homebrew bootloader?How to boot to bank 2?

Can we use encoder mode of a Timer for driving pump and also use same Timer to drive the speaker both connected at different channels.

Hi,My requirement is to use encoder mode of a Timer for driving pump. And using same Timer to drive the speaker. Timer 1 channel 1 would be used for Pump and Timer 1 channel 2 would be used for speaker. Timer 1 DMA is used to output sequence of pulse...

Power supply for STM32F030K6T6 use ADC and use ESP-07S to upload data?

My project use STM32F030K6T6's ADC as AC 230v energy meter then upload to my website's server via ESP-07S. Now my design use HLK-PM01 AC-DC 5v and AMS1117 3.3v to power both STM32 and ESP-07S. Folllow AN2834 each VDD add 100nF ceramic cap + 4.7mF tan...
