As far as I could see from Oleg's sources, all he does is a "soft" reset through the appropriate register accessible via SPI. really? Why is this necessary at all? The datasheet says that the MAX3421E has its own internal POR generator.
I've read the comments about wiring the shields pin 7 RESET to Arduino's RST pin. To be honest, I would like to know why wiring pin 7 RESET to RST is necessary at all? But slowly. So I'm asking this in advance before being able to check it myself and fry the shield. Just got mine and forgot to order the shield connectors. Is there a way I can check which pin has the mistake ? Please help Is there a way I can check which pin has the mistake ? Please helpHi, As I was making the connections I kept checking the value read and it went from FF to 10 but not to 00. Have i made some mistake in the GPIN connections.
Connect GPIN0 to GPOUT7, GPIN1 to GPOUT6, and so on I am getting the below mentioned message for the board_qc I have connected the pin 7 to the reset and soldered all the GPIN connections from GPIN0 to GPIN7 and GPIN1 to GPIN6 and so on. Thoughts? I'm worried that the MAX3421 reads a voltage level off the Vbus line and if I cut it, nothing will work. The USB Shield description says it provides 5V to the Vbus line, but maybe I missed the part saying you need to do steps A and B for that to happen.ġ) Any suggestions on what might be going wrong?Ģ) Can I safely route a 5V line from my Arduino directly to the Vbus of the USB on the Shield? I figure it would be better to cut the existing Vbus line if I can find it, and then attach the 5V line from the Arduino. Both data sheets for the optical sensors in each mouse state 4.25-5V for power supply. I suspect that mouse A can function at that voltage but mouse B actually requires 5V to use it's optical sensor. They both are running at 3.38V at the moment. On a guess, I probed my USB lines directly and noticed that neither the VBus pipe or the optical sensor Vss is at 5V. I have a second mouse (mouse B) with the buttons working, but I cannot get the movement to display. It displays right/left/middle button presses and delta x's&y's for movement. I have got 1 (let's call it mouse A) up and running. I am simply connecting different optical mice to an Arduino Uno through the shield. I'm playing around with my new USB Host Shield and have encountered a problem. After these errors remove I can start with connecting the board.
When I compiled the code board_qc, to check the board, it gave me several errors: board_qc:17: error: 'USB_DEVICE_DESCRIPTOR' does not name a typeīoard_qc:20: error: 'USB' does not name a typeīoard_qc.ino: In function 'void setup()':īoard_qc:27: error: 'E_Notify' was not declared in this scopeīoard_qc:31: error: 'Usb' was not declared in this scopeīoard_qc:33: error: 'rREVISION' was not declared in this scopeīoard_qc:56: error: 'rGPINPOL' was not declared in this scopeīoard_qc:103: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:103: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:112: error: 'rUSBCTL' was not declared in this scopeīoard_qc:112: error: 'bmCHIPRES' was not declared in this scopeīoard_qc:113: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:113: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:120: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:120: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:144: error: 'Usb' was not declared in this scopeīoard_qc:150: error: 'USB_DETACHED_SUBSTATE_WAIT_FOR_DEVICE' was not declared in this scopeīoard_qc:151: error: 'E_Notify' was not declared in this scopeīoard_qc:153: error: 'USB_ATTACHED_SUBSTATE_RESET_DEVICE' was not declared in this scopeīoard_qc:156: error: 'USB_ATTACHED_SUBSTATE_WAIT_SOF' was not declared in this scopeīoard_qc:159: error: 'USB_ATTACHED_SUBSTATE_GET_DEVICE_DESCRIPTOR_SIZE' was not declared in this scopeīoard_qc:162: error: 'USB_STATE_ADDRESSING' was not declared in this scopeīoard_qc:165: error: 'USB_STATE_RUNNING' was not declared in this scopeīoard_qc:167: error: 'USB_DEVICE_DESCRIPTOR' was not declared in this scopeīoard_qc:167: error: 'buf' was not declared in this scopeīoard_qc:207: error: 'USB_STATE_ERROR' was not declared in this scopeīoard_qc.ino: In function 'void halt55()':īoard_qc:220: error: 'E_Notify' was not declared in this scopeīoard_qc:225: error: 'Usb' was not declared in this scopeīoard_qc.ino: In function 'void press_any_key()':īoard_qc:250: error: 'E_Notify' was not declared in this scopeĪnyone have any idea on how I can get rid of these issues? To give it a kick start I downloaded the library USB_Host_Shield_20.
