Most I2C EEPROM (eg M24M01E) need some time after a write command to transfer the written data into the internal EEPROM. During that time (eg max 3.5 ms) the device does not respond to I2C.My question is about the timeOut parameter in the HAL_I2C_Mem...

For these EEPROMs there is a WP pin, which must be (active) low to enable write operations. I am driving this pin from an MCU, (ie. it is not tied to GND).Also these EEPROMs need some time after a write command to effectively write the data into the ...

I am developing an application on the Seeed Lora-E5 module, which contains an STM32WLE5.Currently I am programming the device via the SWD interface, but for future firmware updates I want to use the UART, (this UART is available externally through a ...

I use STM32CubeIde in a fairly standard way, only that I use C++ source on top of the C HAL code. When inspecting the build with Build Analyzer, I noticed A LOT of code which I think I never included.. (never sure what all the HAL files do..) for exa...

I am doing a LoRaWAN project on the STM32WLE and so I want to power it down in Stop2 mode to lower the power consumption.Using the following code, this works fine : UTILS_ENTER_CRITICAL_SECTION(); ...

Yes, the datasheet mentions it. It's easy to miss it, as I assumed that only the RTC stuff was not reset by the reset pin...

Thanks for this explanation, I will investigate the datasheet to see of these debug registers are indeed not being reset by pulling RESET low and so need a power-on reset.I was clearly observing this with 1mA extra consumption on an STM32WLE5 and hav...

Thank you. Of course I combine writes to consecutive addresses into page-writes, but when this address range spans several pages, I have to split it into multiple page writes.

Sure, but the datasheet doesn’t answer the question, that’s the reason I ask it here.Attached is a screenshot of M24M01E-F datasheet. It shows some delay between last I2C databyte and rising WC, but no timing is defined…I could also try to find out w...

Ok, it’s simple : just put it around the forward declaration #ifdef __cplusplusextern "C"{#endifvoid initialise_monitor_handles(void);#ifdef __cplusplus}#endif /* extern "C" */

Why does my build include so many 'unused' functions ?
