Can anyone help me about of my project, I am using Stm32 Nucleo-F303RE and I want to communicate with USB Host shield ( MAX3421E). I’m having trouble communicating with this, Is there a ICSP (In-Circuit Serial Programming) pins to the Nucleo-F303RE so that I can communicate with the module. -Is USB…

Hello Declin, I don’t have any experience with a MAX3421E shield yet, but according to this info the module is equipped with an SPI interface. So you should be able to communicate with it for example over pins D11, D12, D13 (MOSI, MISO, SCK). The NUCLEO-F303RE (STM32F303RE chip) is equipped with I…

How can I communicate with it? I already done connecting the SPI interface of the two boards but nothing happen, different errors. I think the nucleo board and USB Host Shield is not compatible with each other. Any suggestions of other USB Host board? Or do you have a code that can communicate with…

Hello Declin, Sure, I’ll try help you as much as I can. However, I don’t want to lock others out. Perhaps one could find these posts useful and others can help you too. So I’d prefer to keep it public (I hope you don’t mind). I searched the Internet for the MAX3421E shield and found this Arduino …

Here is my sample of wiring, I Already do the wiring between the spi interface of usb host shield and nucleo board, but it seems that it is not working , all i need is a working library for nucleo to interface the usb host shield. [IMG_20200710_160832.jpg]

Hello Declin, You can find my attempt to port the USB_Host_Shield_2.0 library to mbed OS 2 here . An example of using it is here . Since I don’t have a MAX3421E USB shield I was not able to test it. Maybe it can help you get started. Best regards, Zoltan

Hello Zoltan, Thanks for helping, I’ll test it. I’ll let you know the result when I’m done testing it.

Hello Zoltan, Sorry to bother you again, But it seems that your code and library have an error. Here is the error message,See attached screenshot. Sorry I don’t know the coding of this, I’m new on mbed and this is my first project on the Nucleo board. I’m so sorry to bother you. [error compiling…

Hello Declin, It compiled fine for the NUCLEO-F446RE target but there was a name clash with the declaration of the USB peripheral in mbed/targets/TARGET_STM/TARGET_STM32F3/TARGET_STM32F303xE/device/stm32f303xe.h file. I have renamed USB to Usb in the library and also in the main.cpp file. Delete th…

Hello Zoltan, I’m done compiling the code and its success, I just receive an email about the code that is updated. According to my wiring that I sent to you, the connections between the LCD and nucleo board, here is my code. const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2; Is it okay …
