Hello,I am trying to build a BLDC controller using STM32F4. I made a board with the 6 mosfet and drivers, current sensing, Hall sensors input...Is there a ST library for motor control ? I found differents tools (MC workbench), but they seems to be de...

Hello,I try to synchronise 6 PWM outputs for an BLDC controller.I use 3 timers :My target is STM32F446RET6 and I'm using STM32CubeIDE.I read that I add to use master/slave mode. I'm not sure it is the best way, but I configured TIM2 (slave) as follow...

Hello,I created a BLE peripheral using a BlueNRG-MS chip. I can connect on this peripheral using a BlueNRG-M2 (using BlueNRG GUI) and read the services.However, it does not work when I try to connect with an android device (I use "BLE Scanner" app, B...

Hello,I'm trying to follow the test procedure for BlueNRG-MS (SPI) indicated in the Bringing up the BlueNRG and BlueNRG-MS devices - Application note (AN4494).I'm using an STEVAL-IDB005V1D board (with a BLUENRG-MS chip) and an NUCLEO-F446RE board to ...

Hello,I bought an STEVAL-IDB005V1D board with an BlueNRG-MS chip. Is it possible to control the chip with BlueNRG GUI through the SPI of the STLINK-V3SET ?I could do it for a BlueNRG-M2 board through UART, but it does not seem to work with the BlueNR...

What I understand with all your replies, is that NFC WLC (wireless charging) is not a mature technology. There isn't any application note and ST25 datasheet does not give any information about this.For the wireless charging part of my project, I thin...

@RhSilicon Thanks for your answer, the power efficency graph is interesting

@Rene Lenerve Thank, you. You are saying that ST25DV-I2C should be suitable for WLC with an MCU. But we have to "communicate with the Poller through NDEF messages (and manage the WLC protocol)". Is there a guide / application note in order to do thi...

I was about to ask the same question.In ST pdf "NFC charging: The tiniest solution for wireless charging", I read that we have to use "negociated mode" in order to receive up to 1W, depending on the power class.However, in the ST25DV-I2C datasheet, n...

Thanks JW, it helped me. Now it is working only using CubeMX.Here is the configuration of the master timer :Configuration of the slave timer : And we have to start both timers : HAL_TIM_OC_Start(&htim4, TIM_CHANNEL_1); // master timer HAL_TIM_PWM_Sta...
