Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Posted on September 10, 2015 at 09:57Enrico, There seems to be quite complex patented algo with about half a dozen adjustable parameters. I have seen one of your comments elsewhere that suggested some configs can make the circuit unstable and oscill...
Posted on September 05, 2015 at 23:10I am using three L6474s to drive NEMA23 format motors. Using the default register configurations the chips are rapidly getting very hot and causing a TH_WRN condition. I found a post here that stated that the de...

Posted on September 08, 2015 at 07:18 hi i 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...
Posted on July 29, 2015 at 07:49Hi,I've been looking for the pwoerstep01 firmware library, searched on '' http://www.st.com/web/en/catalog/tools/FM147/SC1858 '' .I'm sure there is one, because on my steval pcc092V2 SPINFamily Evaluation Software the...
Posted on June 24, 2015 at 09:56Hi, The L6480 evaluation board (EVAL6480H) is driven by STM32F4 discovery (STM32F4DISCOVERY).The SPI comunication works only without CRC: is it correct?On the contrary CRC is used in the dimostrative FW of STM32F103....

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...
