Rev Log message Author Age Path
331 Added custom SPI LCD interface (pending receive side) and watchdog timer. Also modified system timer II to use aliases jshamlet 257d 15h /open8_urisc
330 Updated to route RAM write fault signal and force CPU interrupts to task manager requirements. jshamlet 263d 22h /open8_urisc
329 Added a core that specifically supports the task switcher software. It merges o8_int_mgr16 with a wide register, allowing full control of I/O peripherals by the task switcher software. This also allows the task switcher to be enabled for the full 16 I/O write qualification lines, which had previously only been supported in the task data setup. jshamlet 263d 22h /open8_urisc
328 Documentation cleanup. Also added operand definitions. jshamlet 264d 19h /open8_urisc
327 More bug fixes:
Added write qual line to LTC2355 interface, fixed bug where output data was duplicating the lower byte in the averager, added an initial romtape.hex file		 jshamlet 265d 00h /open8_urisc
326 Minor comment correction jshamlet 270d 21h /open8_urisc
325 Added the rest of the initializers to the signal assignments jshamlet 270d 22h /open8_urisc
324 Modified the Open8 version of the multi-channel roll average code to have separate interrupt enables for average and flush operations. Note that the flush status bit should be checked by software prior to use if the Autoflush_On_Reset generic is set TRUE.

Also adding the ROMTAPE entity, which acts as a serial-access ROM for storing strings, arrays, etc. in order to alleviate pressure on the primary program ROM. It is intended for use with loops that load fixed content from ROM.		 jshamlet 270d 23h /open8_urisc
323 Forgot to add files jshamlet 271d 21h /open8_urisc
322 Performance fixes for the LCD interface,
Fixed incorrect entity name for the dual LTC2355 IF,
Added a CPU-accessible 8-channel averager core and FIFO-style ROM		 jshamlet 271d 21h /open8_urisc
321 Fixed issue with parity flag in receiver sticking jshamlet 375d 14h /open8_urisc
320 Inverted flow control signals to match EIA-232 specification jshamlet 377d 17h /open8_urisc
319 Fixed off-by-one error in channel count jshamlet 378d 20h /open8_urisc
318 Added o8_scale_conv.vhd and intdiv.vhd jshamlet 382d 22h /open8_urisc
317 Altered the reinit signal on teh adc128s022.vhd driver to be optional, and removed the "dead" signal from the upper level o8_de0_nano_adc_if.vhd code. jshamlet 396d 19h /open8_urisc
316 More code cleanup and comments,
Removed INT_VECTOR_n constants, as they are superfluous. There are no reasonable situations in which the constants would be altered.		 jshamlet 396d 19h /open8_urisc
315 Added Terasic DE0 Nano ADC interface and rolling averager. jshamlet 396d 20h /open8_urisc
314 Code cleanup and added comments jshamlet 396d 21h /open8_urisc
313 Added all generics to package component jshamlet 396d 22h /open8_urisc
312 Added o8_timer24.vhd as a more flexible alternative to o8_sys_timer_ii.vhd.
Also cleaned up some comments in the HTML documentation		 jshamlet 396d 23h /open8_urisc
