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 (...

I am using STM6601CA2BDM6F push button controller in one of my device development projects. I would like to know if I can use this IC for delayed shutdown.

Changing the MOSFET on X-NUCLEO-IHM08M1 to STP110N7F6.

Dear All,​I changed the MOSFETs on IHM08M1 to STP110N7F6 and modified the settings of dead time of Driver and Mosfet in MC work bench. But the BLDC can't run well(it doesn't reve-up often) . The manual of MC work bench only indicate user to modify mo...

I am working with VN5E050MJ-E what are the common fail modes?

The VN5E050MJ-E is used as a over current protections devices. We monitor the current via the current mirror output and disable the device when the current reaches the preset threshold. The threshold is well below the max rated current of the devic...

I would know the value of the internal resistance of the gate to the emitter of this IGBT: STGW80V60DF. Its datasheet doesn't have this information. The IRGP50B60PD has for example an internal resistance of 1.2 Ohms typical.

Is the SPV 1040 suitable for using multiple PV cells in parallel? And how can increase the efficiency for Li-io charging?

HeySo I'm currently building a Solar charger for a 10000mAh Li-Io battery pack and I came across the SPV1040.For the project the charge current does not have to be high so the batterys are just slowly charging but I wanted to use Solar panels with ab...

L6480 absolute position counter value issue

Posted on January 15, 2018 at 10:45HiThe L6480 absolute position counter seems to count in multiples of 256 micro steps? When executing the move command with a 1000 micro steps or using the GoToDir command with a 1000 micro step value both generate ...

SPI clock rate for the 6470/2

Posted on February 20, 2018 at 16:13The data sheet for the 6470 (and 6472) is not clear regarding the SPI clock rate. what is your take on this? the reason why i ask is that a clock rate was selected, boards were built and deployed. all was well. ne...
