Hi I am trying to play a little bit with STM32WLE5 MCU in order to receive raw wM-Bus packages (mode S, T and C). But I need help in setting up the radio part. Is there anyone who can provide a piece of code on how to setup the radio communication fo...

HelloI am trying to implement low power mode with STM32WLE5 MCU (as a part of RAK3172-SIP).However, the current consumption is unreasonably high.I measure around 200uA with 3.6V and around 150uA with 3.3V.Did many tests with different configurations,...

Hi allI have a question regarding the clock output from STM32F446VCT6 MCU.Can anyone tell me whether the clock signal looks good for you?Because for me it looks awful. The signals are measured directly on MCU pin (trace is 2 cm and is not connected t...

Well.... I found the reason why the consumption was too high.The simple answer RTC.If you configure date/time, alarm and timestamp in MX_RTC_Init then the consumption will be on those 200uA.Seems like one should not initiate alarms or date.Now I am a...

No cross talk - I have a PCB where only MCU is mounted, nothing else. Slave is not connected.The "hat" moves closer to the edge when I decrease frequency.

Tried that. I cannot see so huge peak on power line while the "hats" on the spi occur.

Can you maybe run this hex on your board and verify that there is no issue on pin PE12.

I tried with the GPIO output - similar picture. Cannot run it faster than 1.8MHz using GPIO.See the picture. Apart from just normal ringing after the front, there is an additional "hat" after.I tried it on two different boards - I do not have a "refe...
