I tried all 3 available demos: default, FP-AI and Datalogger.At last I flashed the original default demo back. All tests are done USB-powered or with LiPo.Establishing a BLE connection with iPhone works in 10% of the cases.Using an Android smartphone...

Hello.I have a small fan at home with STEVAL-MKI245A attached and STEVAL-MKI109V3 is near the fan as well,like you would using PROTEUS1.The fan offers 3 mechanical switches to modify the speed.Using the switches causes a stop of reading data from the...

libncurses5 and libtinfo5 were replaced by libncurses6 and libtinfo6 in Ubuntu 23.10.No Debug possible anymore inside IDE.Update not yet available.Is it safe to replace version 11.3 of the toolchain with i.e. 13.2?Will it work to overwrite the plugin...

1.) HAL_Delay(x) hangs forever when restarting CM4 using Hardware Timer for Systick. Every unit was forced with RESET/RELEASE. Any firmware change could not solve it. Have to repower the board. Happens in Normal and Engineering mode!2.) HAL_Init() ha...

Hi Federica,Thank you for the information.Looks good!All issues I mentioned are fixed with STSW-PROTEUS1 v1.1.1.I suggest to use the BLE stack version 1.20.0 from Github project STM32CubeWB, released 5 months ago.Version 1.19.0 would be a downgrade, ...

Hi @Federica Bossi ,The adapter board is connected via USB at the notebook which uses it's own battery, no power supply.This means everything is isolated from AC power.It's just a fan (as a vibration source), STEVAL-MKI245 attached to STEVAL-MKI109V3...

Open STM32CubeProgrammer and connect via ST-Link.Click on "OB" for Option bytes.Open tab "User configuration" and look for "BCM4" and "BCM7".In your case you want BCM4 to be checked as well as BCM7.Click Apply and Disconnect.

Unfortunately this issue still exists.I use TIM17 for Systick. I start the CM4 fimware, stop it and start it again.It hangs at HAL_Delay(5).My code lines before HAL_Init():TIM_HandleTypeDef htim17;htim17.Instance = TIM17;HAL_TIM_Base_Stop_IT(&htim17)...

SOLVED. I forgot to initialize with VIRT_UART_Init(&huart0);
