Not working on ftdi chip

[theMASTERMINDpK]

I'm trying to connect USB host shield with the device having FTDI Chip to provide virtual com port. But failed to build a connection between host and device. I'm using USB host library 2.0 available on GitHub. Does anyone knows how to Implement FTDI on this library?? Some device specs are listed below: VIRTUAL COM PORT Baud Rate:9600 baud Format: 8 data bits, no parity, 1 stop bit Protocol: Modbus over Serial Line

Ftdi is supported in UHS 3.0. it is emulating CDC ACM with extensions. Try the CDC ACM example code. If the vendor ID or device ID is not recognized and it really is an ftdi part you will need to supply that information to me so that I can support it.

Hi thank you for help. I tried that example but failed. My device spec are as follows: Description: USB Serial Converter(FTDI FT230X Basic UART) Device Type: Vendor Specific

Protocal Version: USB 2.00 Current Speed: Full Speed Max Current: 90mA

USB Device ID: VID = 0403 PID = 6015 Serial Number: DO2IZ7XE

Device Vendor: FTDI Device Name: FT230X Basic UART Device Revision: 1000

Controller Part-Number: Unknown

Please turn on debugging and post the entire output. This chip may have a quirk I need to do a fix for. I will have to see if I have this chip in my FTDI collection...

When i compile the code each example gives me the error: Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno"

Bug fixed. Please use an Arduino Mega. The Arduino Uno does not have enough memory to run this library at this time, but MIGHT in the future.

thanku i'm going to arrange arduino mega and will try. I'm trying This FTDI chip with UHS 2.0 and got some success in getting response after changing the PID value according to sensor in the libarary

Everything is working fine. Return codes showing success but the output is not correct. I'm sending 8 bytes of ch array with rcode=0vand should get 7 bytes of data but getting"0x01 0x60 0x60" Here is example code given in UHS2.0:

I am aware of the cross post. :-)

Have you read the instructions for AVR? Specifically: Connect pin 9 to pin 3 with a jumper wire. Let me know if it works after that...

[theMASTERMINDpK]

I tried the sensor with arudino mega 2560 by connecting pin 9 to pin 3 with a jumper wire. And received the debug messages. At last temperature sensor is connected 👍 . And I don't know how to send and receive bytes in this example. Here is a video of my temp sesnsor working with serial terminal: https://www.youtube.com/watch?v=B1S0dRWjoZA&feature=youtu.be

Here is the example which i uploaded on arduino Mega https://github.com/felis/UHS30/blob/master/libraries/UHS_host/UHS_CDC_ACM/examples/USB_HOST_SHIELD/acm_terminal/acm_terminal.ino

So you want to do this manually like the program you show in the video? or automated?

[xxxajk]

You would do it much the same way as you do in the other attempt that you wrote.

1: Send the array 2: Read 1 byte at a time until you fill a new array, the driver has the capability to do this in the background. See the buffered demo for how to do that. IMPORTANT! You need to enable and disable polling while accessing the buffers. See the comments in the demo. In your case, wait for 8 or more bytes. 3: do whatever processing you want to do with the returned data.

[xxxajk]

all you need to do is... write your data, then wait... e.g.

while(Bcm->rd_available() < how_many_bytes_you_want) yield(); // wait then read your data, and do whatever you need to do with that data.
