Greetings,What is the reason for not being able to use the SMPS (or the SMPS supplying LDO) option for VOS0 on STM32H745II?VOS0 means the highest voltage, so won't the dissipation on the LDO be the highest?I have been using the PWR_SMPS_1V8_SUPPLIES_...

Greetings,what is the recommended frequency deviation parameter for the FSK modulation with 250 kbps bitrate?Or rather what is the dependency of RX sensitivity in relation to the FSK_FDEV parameter?I can see that the limitation is to have the modulat...

Greetings,can you please tell me where can I find the version history for the STM32CubeWL Release v1.2.0?Latest version on GitHub is for v1.1.0.Specifically, changes in the "radio_ex.h" and the related files since your examples on the GitHub repo don...

Greetings!I'm designing a board using STM32WLE5CCU6 MCU and decided to use a 32-MHz Clipped Sine Wave TCXO instead of a crystal for the HSE32 clock.I have a question regarding the additional circuitry between the TCXO and MCU, is an AC coupling capac...

I have new info from the ST support, this option is ok and a fix will be provided in the STM32CubeMX 6.9.0.

Compare the measured results to the Table 61. on the page 153. in the datasheet (Electromagnetic Interference (EMI) section).Emissions should be around 5 dBµV in the 0.1 to 30 MHz band.If the results greatly differ from this, then the cause of excess...

What was the clock speed used in this example?Keep in mind that this 40 kΩ weak pull-up in combination with line and input capacitances is forming a low-pass filter.So it depends how long and wide your PCB traces are (rule of thumb is 1 pF/cm length ...

Yes you are correct that was a brainfart, I meant higher current.

@Community member unfortunately, I don't have the ability to change the FW on this board, but I'm measuring the case temperature to be 44.7 °C using the thermocouple.I'm using the UFBGA176+25 package and according to the datasheet, junction-case the...
