Reducing the number of sensors enabled in the configuration file helps, as does slowing down the SD clock (i.e. increasing hsd1.Init.ClockDiv = n in STWIN_sd.c). We've also noted that the code in sd_diskio.c has the compile time build define "ENABLE_...

On the STEVAL-STWINKT1B board, and using the HSDatalog firmware, it uses about 60mA in idle state. I have disconnected the sensors, and the uC, and turned off the SD card power lines, but it's still at around 2mA. Does anyone know where this power ...

When I compile the code in the IDE and run it (with the acquisition json file set to activate for 5s, then idle for 10s, and repeat) It activates correctly the first time. However, when coming out of idle the second time, it produces an SD card erro...

Thanks. We are also finding unreliability to saving files to the SD card. Sometimes the files end up corrupted. Sometimes the microphone data is temporarily corrupted. We are trying out various specs of SD card to see if we can improve the perfor...

Good to know.We have also found in the release software the size of the memory allocation at startup causes the SD card to crash when coming out of idle state. If that is fixed, as well as enabling a very low current when idle mode, it will save us a...

OK. That makes sense. Unfortunately the microphone is key to our project. What are the current project timescales for release of a rev2 board?Laurence

Hi Eleon,That was our prime suspect. Thanks. It is frustrating given what we want to use the board for. I think we are going to try and reconfigure the power supply to the 2.7v LDO such that it comes from DCDC2 instead, and so is switchable. Not ...

Steval-STWINKT1B - Where is all the power going?

On the STWIN SensorTile Wireless Industrial Node, the standard en.fp-sns-datalog1_v1.2.0 firmware behaves differently if using the binary, rather than compiling the code in the STM32Cube IDE.
