I am using the STEVAL-STWINBX1 development board with the FP-SNS-DATALOG2 software.I am struggling to configure PB1 as a digital input for an external interrupt (which is on pin 12 of the expansion connector CN1)... I start by opening the .ioc file i...

Why does the datalogger crash when I put a device_config.json file on the SD card ?I created the device_config.json file using the Python GUI tool, saved it to the computer and then copied it to the root folder of the SD card. The only changes I made...

Is there a MATLAB script to plot and export the .dat files saved by the STWINBX1 datalogger ?

I am using the STEVAL-STWINBX1 development board and have downloaded the FP-SNS-DATALOG2When I open the help file FP-SNS-DATALOG2_Package.chm (in STM32CubeFunctionPack_DATALOG2_V2.1.1\Documentation) it appears to be empty other than the index...Why i...

Does this mean that the only method to get WiFi working is to use the Android app ?There is no other alternative method ?

I've found where PB1 pin is being changed, it happens during the debug pin initialization, where the code appears to initialize all the pins on the expansion connector.So I commented out line 161 and now GPIOB->GPIO_MODER->MODE1 remains set to 0x0 (i...

I cannot get the external hardware tag to work, because port pin PB1 is being set as a digital output i.e. GPIOB->GPIO_MODER->MODE1 = 0x1Step 1: PB1 is initially set as a digital input i.e. GPIOB->GPIO_MODER->MODE1 = 0x0Step 2: The clock disable then...

After HAL_GPIO_Init(EXTSYNC_GPIO_Port, &GPIO_InitStruct) is called, register GPIOMODER.MODE1 is 0x0 and PB1 is pulled up to 3.3V as expected.... But register GPIOMODER.MODE1 changes from 0x0 to 0x3 after __HAL_RCC_GPIOB_CLK_DISABLE() is called...Afte...
