Posted on July 24, 2015 at 02:56Hi, i get start to test a L6470H discovery board and got some problems:1.i try to connect board and pc with usb cable but it shows unknow device in windows device manager in win7-64bit but works fine in win xp 32bit.(...
Posted on July 24, 2015 at 04:17hii got a L6470H disc board and try to run the source code from (dSPIN_Firmware_Library_STM32) and (dSPIN Discovery Kit) project both of them get SPI communication fail: any read of spi get 0xFF, the board is new and ...
Posted on July 18, 2015 at 05:04What is the filter cap required for driving a stepper motor at 5 amps RMS? The schematic from ST shows 220uF 100V but no ESR data. I placed a United Chemi-Con 390uF 100V with an ESR of 28m ohms and a ripple current of...
Posted on June 22, 2015 at 16:05I've been encountering a strange problem. I can use the L6474 to move a stepper motor pretty fast in the forward direction. When I flip the direction bit though, I find that I can't make it move anywhere near as fas...
Posted on June 30, 2015 at 15:58Running a bidirectional stepper at 30V with L6482 and getting actual stalls in 16-microstep mode -- under load the motor literally stops and hums, but nothing is reported back to software. It's like the driver has not...
Posted on June 10, 2015 at 10:16Can i interface a quadrature encoder to stm32 without using the channel 1,for example using the channel 2 and channel 3 .
Posted on June 14, 2015 at 20:55Hello I am new to dSpin, but straight to the question.I have a L6470h setup on a protoboard using schematics found in the usermanual.But I see that the chip gets very hot even though it is in HiZ state. I measured the...
Posted on June 30, 2015 at 16:04The manual describes the function of TBOOST well, but none of the examples of configurations that I have seen show the parameter set to anything besides 0x00, or really when it would be useful to implement it. Could s...
Posted on June 09, 2015 at 19:01Hello,I just wanted to know the required current capacity for VH and VL for EVALSTGAP1S. I am using it fior SiC , VH=20V and VL = -5V.
