Let's read the Internal Temperature Sensor on #BL602 and #BL604
https://github.com/lupyuen/bl_iot_sdk/tree/tsen/customer_app/pinedio_tsen
From #BL602 Reference Manual: The Internal Temperature Sensor is accessed thru ADC

Reading the #BL602 Internal Temperature Sensor looks complicated ... But there's an easier way!
https://github.com/bouffalolab/bl_docs/tree/main/BL602_RM/en
#BL602 ADC HAL provides a helpful function for reading the Internal Temperature Sensor: "bl_tsen_adc_get"
https://github.com/lupyuen/bl_iot_sdk/blob/tsen/customer_app/pinedio_tsen/pinedio_tsen/demo.c#L1-L27
Reading #BL602 Internal Temperature Sensor with "bl_tsen_adc_get" has 2 issues ... 1️⃣ First reading is always too low ... 2️⃣ Result is returned as Integer even though the reading is actually Float
Let's copy "bl_tsen_adc_get" from #BL602 ADC HAL and fix the issues ... 1️⃣ Temperature is now returned as Float (not Integer) ... 2️⃣ Insert a delay during init to fix the first reading
Here's how we call "get_tsen_adc" to read #BL602 Internal Temperature Sensor as a Float (instead of Integer)
#BL602 Internal Temperature Sensor is now read as a Float ... And first reading is always correct! 🎉
Let's create a command to transmit #PineDio Stack BL604's Internal Temperature to #TheThingsNetwork
#Grafana receives #PineDio Stack BL604's Internal Temperature from #TheThingsNetwork ... And renders the Temperature Chart correctly 🎉
#Roblox also happily renders #PineDio Stack BL604's Internal Temperature ... Received via #TheThingsNetwork 🎉

What's Next for #BL602 and BL604? Prometheus, Grafana and The Things Network!
Here's how we read the Internal Temperature Sensor on #BL602 and BL604 #RISCV SoCs ... And transmit to #TheThingsNetwork over LoRaWAN
#TheThingsNetwork works great with #Prometheus and #Grafana! 🎉 ... More about this in the next article
