Posted on July 24, 2015 at 04:18hii 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 23, 2015 at 09:59Hi, 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 September 06, 2015 at 05:49hi, i bought a 6470h disc board and found a problem that spi communication always fail, whatever spi command send from mcu the driver always back 0xff. and i checked spi signal with oscilloscope, the only thing i...
Posted on September 01, 2015 at 22:16HI, I am using an L6470 and have a situation where I must stop motion immediately if an obstruction (think someone's hand) crosses an IR beam. Motion must stop immediately and not via any commands since there can...
Posted on September 01, 2015 at 15:21Hello Experts,I am using a bipolar stepper motor and L9942 driver IC.I am unable to set the stall threshold time for my application. The stall position to be identified is the end position of the linear actuator....
Posted on July 23, 2015 at 13:32I am a newbie to Stepper Motors. I am working on L9942. The different modes that it can chop the current are Full mode, 1/2, 1/4 and 1/8. When 1/4, 1/8 modes are used with lower STEP Frequency or when Full and 1/2 mo...
Posted on July 21, 2015 at 20:55I need some help on a drive controller that I designed that uses two L6482's. The problemis sometimes while running, one motor will shut off. Reading the status register shows an over current condition. The testing cu...
