According to the LoRa-E5 datasheet V1.0 on pg 6/18, there are several pins labeled as “MCU GPIO” which implies that these are the actual pins from the ARM uC. According to the STM32WLE5JC datasheet (ST DS1305 rev 4, ppg 48-52), several pins (up to 14) can be configured as inputs to the ADC.
The table in LoRa-E5 datasheet V1.0 on pg 8/18 the LoRa-E5 datsheet table contains: “ADC 1 ADC Input, include 1pins,12-bit 1Msps” which implies only one input can be used.
Which of these is correct and if there really only is 1 ADC pin available… Which one is it?
Ok. So please verify my own answer to my original question.
Based on “LoRa-E5 datasheet v1.0”, PB13(24) and PB14(26) are pinned-out from the silicon. I should be able to configure PB13 as ADC_IN0 and PB14 as ADC_IN1.
I have erased the part and do NOT wish to use the Seeed “AT command” firmware and do not care that PB13 was used as a bootloader request by the AT firmware.
Can you please verify? I have a PCB ready for manufacture and need to know this before proceeding.
Thanks.
Thanks, Citric. I think I’ve answered my own question by reading some voltage from pins pb13 and pb14 by modifying the Lora-e5-end-node example with success. Thanks for passing this on as well!
