I’m designing my custom Lora E5 board and it will be programed with the STM32CUBEIDE.
I saw the PingPong example with the stm32wle5jcc and im having some trouble porting it to the LoraE5.
Are those GPIOS not available externally, available internally? To drive the subghz aplication I need to use 3 GPIOS “RF SW CTRL”, can this be used with internal gpios although they are not externally available?
Thank you for your time.
+1 to this. CubeMX asks me to set these 3 GPIOs and in the product page there´s not enough information:
Info on the Lora E5 page:
- Clock Configuration:
- 32MHz TCXO
- TCXO power supply: PB0-VDD_TCXO
- 32.768KHz crystal oscillator
- RF Switch
- Receive: PA4=1, PB5=0
- Transmit(high output power, SMPS mode): PA4=0, PB5=1
Thanks in advance!
Sorry, found out that there is a CubeMX example here:
Im trying that code and it works, but that´s not what I’m looking for. I want to create a simpler version, just sending messages between 2 boards and there’s still an error with the RF SW CTRL 3.
