Posted on April 15, 2013 at 13:00Hello! I have STEVAL-PCC009V1 and EVAL6470H boards and wondering:1. What software should I use with STEVAL-PCC009V1?I tried it on Win-XP, after installing drivers it was recognized as Universal Dongle Demo Board. But...
Posted on August 15, 2013 at 15:37I am working on a BLDC motor implementation. The motor has 4 Pole Pairs with 3 hall sensors. I am storing the time between any successive hall sensor interrupt. The time between hall sensor interrupts is (TIMER * ...
Posted on March 31, 2013 at 20:22Hi,I have been trying to adjust the BEMF compensation parameters for my stepper motor on a EVAL6470H board. I am using the Dspin evaluation software on WindowsXP and an STEVAL-PCC009V1 communications board. I am mo...
Posted on March 21, 2013 at 12:06I load down my own program to PCC009V2 ,after that i found i can't use the PC GUI to control the L6470 ,for the mistake is i can't connect the pcc009V2. why this happen ? Is that in the PCC009V2 had write some specia...
Posted on July 26, 2013 at 05:37We bought IGBT driver ICs, from element14.. L6388ED, L6390, L6386...all those ICs dont have any markings to find, which pin is No.1. Usually all ICs have dot mark to indicate PIN.NO.1, or U mark at the top of IC. But...
Posted on July 16, 2013 at 16:10Hello, I am evaluating the L6470 as replacement for a discontinued chip, which is used in our application in the moment. I have to reach high speed (2500 step/s), however when going above 800 step/s the motor looses ...
Posted on July 09, 2013 at 03:09Accoding to the IC datasheet, the number of bytes during a spi transfer can be 1 to 3 bytes, with a single chip select at the start..however, the sample code (for set/get parameters) calls easySPIN_Write_Byte for EVER...
Posted on July 30, 2013 at 09:56I used VIPer53 in my product,I found that some of them entered into overheat （about 65℃） protection mode after running 70~180 mins at out power was 17W, and my design output power is 30W at Vin=220Vac. Change another ...
Posted on July 21, 2013 at 14:57I wanna ask ST for replacement for LDO with multiple outputs L4909I read that this product was obsolete and i wanna use one with the similar function So, can you provide me with the replacement for this part ?Thanks
Posted on July 19, 2013 at 06:33Hello...I want to chop the DC so that 585VDC into 400VDC. I dont know How to Connect the gate of IGBT w.r.t Emitter. Because Emitter here is not at zero or Grounded, Its floating. The ground of Microcontroller connect...
