Recommended MCUs for Low Quality Cameras

2021-09-23
Hello,I would like to use a microcontroller which keeps around 600x800 pixel one image comes from a camera and compresses it. They are very simple functions. It needs at least 600 kB RAM to keep one image. However I could not find a low-cost microcon...

Do I have to use a 32 kHz oscillator (LSE) for the STM32WB55 MCU ZigBee application?

2021-06-10
Hello,I am going to use a 32 MHz oscillator (LSE) for a ZigBee application on STM32WB55. Do I have to add a 32 kHz oscillator? I do not need RTC. Best regards,Batuhan

I2C Bus pull-up resistor for multiple slave devices

2021-06-04
Hello,I am using multiple different sensors which require different pull-up resistors. For I2C BUS, I have to use just one pull-up resistor value for all sensors. How can I calculate or decide the resistor value? MCU is STM32WB55.Sensors are VL53L3C...

Can I leave INT pins unconnected for the LSM6DSO accelerometer and gyro sensor?

2021-06-04
Can I leave INT pins (INT1 and INT2) unconnected for the LSM6DSO accelerometer and gyro sensor?In the "internal pin status" table It says that the INT2 pin is forced to connect to ground. I use neither INT1 nor INT2 in my project.Thank you,Batuhan

Do I have to use an external resistor for the HSE oscillator on STM32WB55 MCU?

2021-05-26
Hello,Depending on the datasheet of the STM32WB55 MCU, there is an external resistor for the oscillator circuit. In many Nucleo board schematics, it is not used. The datasheet says that the resistor is to avoid overdriving current. How can I decide t...
