ecos RTOS 原理介紹和應用開發The design philosophy of eCos was to augment an open-source RTOS (which meant no
per-unit royalties) with source-level con?guration tools that would enable embedded developers
to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu-
ally change a line of source code.
This program sets up EVA Timer 1, EVA Timer 2, EVB Timer 3 and EVB Timer 4 to fire an interrupt on a period overflow. A count is kept each time each interrupt passes through the interrupt service routine. EVA Timer 1 has the shortest period while EVB Timer4 has the longest period.
