Hi,I want to implement button interrupt with time period to send the mcu to Dee-sleep ,and wake up. For example; When I press button for 5 sec, MCU will go to sleep, when I press the button second time for 5 sec MCU will wakes up. but I don't know ...

same code works on L476 MCU, this issue happens only on L072 mcu

yes I shorted RX pin to TX, should receive what sent from tx, but I only receive first letter

Button interrupt with time period

I am trying to read UART and to hold on rx_data array. when I send "AT" to rf module it returns "OK" , but on my code I cannot receive anything from UART. and help appreciated

I need connect camera with HDMI output to STM32 MCU. Goal. Take image/short video from camera, and send to another device using SPI. Can somebody help with info what type of MCU I can use for this? If ST have appropriate devkit it will be great.
