STSPIN32F0601TR's number of GPIO

HelloI want to ask about STSPIN32F0601TR.I'm reviewing the IC for motor controller, in datasheet it describes the number of GPIO 21.but counting the number of port N. Name Type Function1 PB8 I/O - FTf MCU PB84 PC13 I/O - TC MCU PC135 PC14 I/O - TC MC...

For POWERSTEP01 is it possible to tell what the maximum speed of my stepper motor in VOLTAGE mode could be.

I am using a POWERSTEP01 at 48V in VOLTAGE MODE.Here are the motor parameters. Also does this calculator assume a 0.9 degree stepper motor?Is there an inherent speed limit (microsteps/sec) for VOLTAGE MODE?Why is CURRENT MODE capable of higher speeds...

I am trying to do laser engraving with a POWERSTEP01. But I get high frequency oscillations on my motor.

I am in current control mode, and the stepper motor is using about 3 amps.Is there anything I can do to reduce these oscillations.Also note that the white line is about 0.010" thick.I am using x16 microstepping, and I currently have 1600 microsteps p...

We are using STC3117 Fuel Gauge. Can we read a configured RAM data from one device and write the same RAM data to another device and if yes how??

We are using STC3117, and we are performing a charge and discharge cycle to avoid any battery fluctuation issue so if we need to do it with mass number of device, it is not possible to perform same task so can we perform this in a device and get RAM ...

Can we remove VSS power from 8 daisy chained L6470s but keep them powered by 1 external 3.3VDC supply via the VDD pins (ref. section 1-3 of ST Micro note AN4241) w/o damaging the parts? Will the L6470's retain their parameters w/o VSS but with VDD on?

Hi, I am using STPM32 with Rogowski coil, Can I use antialiasing Filtering (Double RC pole) from Coil to IINP and IIN? Thank you

viper222 design help

as shown in pictures datasheet and e designsuite both have different pin names for the same ic viper222 can anybody help regarding this topic please.thank you

ST Micro app note AN4241 shows ways of connecting logic power on L6470's to external 3.3V & 5V supplies. For external 3.3V it shows VREG & VDD are connected. Is this correct? It seems like the internal L6470 3.3V would content with the external.

I am new to ST family. For my new project i need to use stspin32f0601 for BLDC motor drive application, and also i want to know stspin32f0601 need to program or pre loaded BLDC drive program? If need program i need some example codes for BLDC control?

Has anyone experience with current limiting of motor drive VNH7100 and L9960 with stm32L433?

Hello, I am using the stm32L433Rc and a maxon motor (9 V, initial current 11,4 A, continous current 3 A). Now I am looking for a motor drive inbetween. I am thinking of using the a) VNH7100 or b) the L9960. Has any one experience with one of these? I...
