How to adjust driving current with STSPIN820
I use STSPIN820 to drive the stepper motor, which is noisy when it runs at low speed. I tried to reduce the supply voltage and the noise problem improved, but still could not meet the use scenario, although I reduced the voltage to the chip allowable...
Troubleshooting with spv1040 panel shunting
Hi!We developed a device using the SPV1040 as a DC-DC converter connected to the PV panel (5V MPPT 0.150A sc)When the no-load voltage of the panel is less than 2 volts, but the same panel when connected to the converter produces a much lower voltage....
Why do the output of the bridge rectifier shoot above 1KV when an inductor is placed as a filter in series with it?
Hi,I am designing an inverter using ST's application note AN2794.I have customized the application note which was designed for 1KW power to 1.65KW.The problem i am facing now is that when i probe the output of the bridge rectifier placed at the outpu...
Resolved! Always get STUSB4500 Not Detected message when using NVM GUI
I have checked and re-checked this. Also used another USB to I2C converter and can read the registers just fine. Put an I2C analyzer on the setup and I see no activity when the GUI program starts.Today on Github I found a HwCheckUtility.exe file. It ...
Resolved! two different IPS160H pinouts found
I am using IPS160H switch as a power switch input to DC/DC converters. But now I am confused to see a discrepancy between the data sheet and the STEVAL-IFP028V1 evaluation board schematics how to power the chip (Vcc). a) In IPS160H datasheet it says ...
ISSUE in en.x-cube-spn3 code
Hey,I note That There is an instruction ERROR in en.x-cube-spn3 code.in Powerstep01_SetDeviceParamsToGivenValues(uint8_t deviceId, powerstep01_Init_u_t *initPrm); function of powerstep01.c file, at line 1912 to 1914, the instruction, " Powerstep01_Cm...
Hello, I am using three L9942XP1TR driver ic for controlling three stepper motor.
The spi communication is interfaced to driver ic from raspberry pi(.Interfaced with raspberry pi using I2C for my project.The 3 gpio pins MCP23017(pin8,21,22) drives the enable pin of 3 l9942xp1tr(U3,U4,U5).Please refer image.While programming, after...
What is the default power on value of config register for L6480 stepper motor ic
In the March 2015 datasheet it says that the hex reset value for the config register is 2C88. When I try this on my actual devices (4 of them) I get back 2C08. Based on the value this means that the OC_SD bit is set to 0 - Bridges do not shut down (...
