;; This is an example of how to glue the components in Staapl together
;; to get to an interactive console. It loads and compiles the monitor
;; code, uploads it and presents a target REPL.

;; To use, install PLT scheme and piklab. On the hardware side, it
;; uses a serial port on /dev/ttyUSB0 and a microchip ICD2 programmer
;; connected to a PIC18F1220 chip.

;; Load this example as "mzscheme -p zwizwa/staapl/examples/upload-monitor"



;; Create a project with an instantiated PIC18 Forth dialect.
(require
 (planet zwizwa/staapl/prj/pic18)      ;; PIC18 compiler in a namespace
 (planet zwizwa/staapl/prj/pic18-repl) ;; interactive console
 scheme/runtime-path)

;; Load the interactive monitor target code. The 'define-runtime-path
;; is only here to locate the .f file is in the installed
;; distribution.
(define-runtime-path mon "../pic18/monitor-p18f1220.f")
(forth-load/compile mon)

;; Write object data + meta data to disk.
(save-ihex "monitor.hex")
(save-dict "monitor.dict")

;; If you have a PIC18F1220 connected to an ICD2 programmer and have
;; piklab-prog installed, this will upload the just generated .hex to
;; the target, and switch it on:
(prog "monitor.hex")

;; With a serial cable connected to the target, it is possible to
;; interact with it using a serial connection and the 'forth-command
;; based REPL.
(current-console '("/dev/ttyUSB0" 9600))
;; (current-console '("/dev/ttyS0" 9600))

(repl)

;; Now, create a forth file and type 'ul <file>' to replace the
;; current uploaded application (if any) with a freshly compiled one.
