Beginners question: IHM01A1 + Stepper - What am I doing wrong
I am an owner of the STEVAL-EDUKIT, an inverted pendulum kit by ST with an NUCLEO-F401RE, IHM01A1, Nema17 motor and an rotary encoder + a 2A, 12V power supply. I have no prior experience with motor control whatsoever. See https://www.st.com/content/s...
Which pin is used as output for connecting load on spv1050 ? i need to connect load .
i am trying to charge li ion battery. the power should be available all the time , even if there is no harvesting in process.#Spv1050
IHM01A1 Shield project - How to create from scratch?
I am using a IHM01A1 Stepper motor shield with an STM32F401. The provided example for one motor from the X-CUBE-SPN1 package works as expected and I can properly control the motor.Now I want to basically recreate the project from scratch as a prober ...
Resolved! IGBT gate resistance value calculation.
Q1. How to calculate IGBT gate resistance.I want to use STGD18N40LZ IGBT for operating an inductive switching load. Switching freq:- Between 400Hz to 1KhzCollector to Emitter voltage:- 24V.Avg Max current :- 5A.Q2. What will be impact If I use 1Kohm ...
Resolved! high input voltage into an L7805 - would like to add a resistor to drop Vin, but not sure how to calculate
In the datasheet, it gives a formula, R = (Vi(min)-Vxx -Vdrop(max)) / (IO(max)+Id(max))My IO is 0.1A, My output voltage is 5V. My input is currently 24V. I saw some discussion that I think I should consider the Vdrop to be 7V. Is Vxx the voltage I...
Resolved! [STSPIN250] Monitor the current in real time?
Can we connect SENSEA/SENSEB pins to microcontroller ADC inputs to monitor the current in real time?
Need HAL Driver to drive ST's LED1202 - 12-Channel Current LED Driver
We are using ST's LED1202 - 12-Channel LED Driver in our hardware. Which is connected with MPU using I2C. But i am not able to find any HAL Library to drive this IC. ST is providing only binary firmware which works with Nucleo board [here].Please he...
L6599AT gate drive pulses appear unexpectedly
We noticed that there are pulses at the gate drive outputs (pins 15 HVG, & 11 LVG) during the ramp-up of the control voltage (pin 12 VCC).This is what we saw: when VCC reaches about 11V, a sequence of pulses appear on both LVG and HVG. First LVG went...
