I'm trying to communicate with L9963E using SPI mode. MCU is 16bit dsPIC microcontroller. Can someone share some sample C programs related to Initialization and single access read of L9963 registers?
I am using EVAL-9963EFrom datasheet, when SPIEN pin of L9963E is connected to VCOM and R43, R46, R57, R138, R139, R140, R141, R143 are assembled, L9963E is now ready to use direct SPI (normal SPI without isolation). 1 MCU communicates with 1 L9963E o...
I've selected L99LD21 LED driver for my application. I need SPI register map for configuring the device. Could anybody support me please.
According to the datasheet of the powerstep01 driver, a minimal baudrate of 5MHz has to be respected for the SPI interface. Is there any technical reason for that or can a lower (lets say <1MHz) baudrate be used for communication?
Apart from the V_RMS, I_RMS, power and energy (all aggregated), is it possible to output the ADC readings real time over SPI? I am looking to get 8k samples of I and V out of it. As of it was a pure ADC, with the filtering, but without the calculatio...
I have designed a board with four seemingly identical motor drivers. The four L6472 are connected to an STM32-MCU via one SPI-interface, chipselect is handled by GPIO. They share a common reset signal, also GPIO. Because of the pull-downs on /STBY_RE...
Hello,we are new on this products.The connection is between stm32f765ni mcu to the AD9484 device under Half-Duplex spi communication.From the datasheet what we understand is the following procedure:HW:First Bit: MSBData Size: 16 BitsBaud RAte: 27.0 M...
Posted on May 19, 2018 at 14:02Hi, I am working on STPM32 with ESP32 IDF I am not able to write the values to resister while configuring , read and right functions are working properly but whenever I read the configured resister I am getting defaul...
Posted on May 21, 2018 at 16:33It is necessary to apply a opto-coupler between an SPI Master and the L6470 circuit on the X-NUCLEO-IHM02A1 board ? I could not find any information about galvanic isolation in L6470 documentation.#x-nucleo-ihm02a1 #op...
Posted on August 01, 2016 at 22:00Hello! With Atmega regular hardware SPI, data transfer is 8-bit. Hence, when asserting commands, followed by receiving/transmitting data from/to STLED, each transmission will look like 2 8-bit packets separated by h...
