See also: Display, BitmapBoot Tool. Schematic Typical connection of a Display Signals This is the signal-mapping, when using 8/16Bpp displays. 18Bpp is not supported in the current Windows CE drivers, because of it many disadavantages compared to the win of 2 extra display-lines. If needed LDD16 and LDD17 are mounting options on pins 150 and 152 of the Trizeps-module. If more display-lines for each color are availlable for a display, tie th… text/html 2009-11-06T10:19:39+02:00 http://www.keith-koep.com/service/doku.php/service/hardware/appnote/connectquaduart Applies to: Trizeps-IV, Trizeps IV WL, Trizeps-V.

See also: UART Serial Port & IrDA. Schematic FFUART (COM1) to RS232 This is a sample on how to connect COM1 to a DSUB9-RS232 connector. Like almost all of the Trizeps-signals, the COM1-pins are only +3V3-tolerant. text/html 2009-06-05T11:08:02+02:00 http://www.keith-koep.com/service/doku.php/service/hardware/appnote/connectusbhost Applies to: Trizeps-III, Trizeps-IV, Trizeps IV WL, Trizeps-V. See also: Schematic Typical connection of USB-Host-Connector * Place 15K pull-downs near USB-connector. * For best compatibility with all modules, mount R24 and R29. * For a cheap solution, where overcurrent-detection is not needed - i.e. when using on-board USB-devices - U10 may be ommited. Though the Trizeps has a weak pull-up on USB_OC1 and USB_OC2 pins, an extra pull-up is recommended. Note that those pull-ups need… text/html 2009-05-29T15:34:20+02:00 http://www.keith-koep.com/service/doku.php/service/hardware/appnote/connectusbslave Applies to: Trizeps-IV, Trizeps IV WL, Trizeps-V. See also: Schematic Typical connection of USB-Slave-Connector When choosing a protective-diode circuit (D1), choose one that has not got an internal pull-up! If the USB-Slave is used for debugging-purpose only or if you need to reduce part-count, the reset-generator logic could be removed. Leave the voltage divider and maybe include a capacitor for signal-debounce. text/html 2009-05-08T10:06:29+02:00 http://www.keith-koep.com/service/doku.php/service/hardware/appnote/tr4m_portingguide Existing designs need not be changed. The default pull-up/pull-down behaviour during processor reset has changed. This is only an issue, when a design relies on a specific pull-behaviour. A modified USB-Host-driver is needed, because of an processor-issue. This might require a new operating-system image. text/html 2010-08-09T13:16:43+02:00 http://www.keith-koep.com/service/doku.php/service/hardware/appnote/trizeps6_cpld This page explains the default-functionality of the Trizeps6 CPLD. Keith & Koep can deliver Trizeps6 with customized CPLD-content. In example if not needed, the 26 address-pins of the Trizeps6 may be used as GPIO or one of the UART's can be multiplexed to allow even more serial-ports.
