Misc software and routines for the TS silabs supervisory microcontroller. These routines are intended to work equally in uboot, linux userspace, or even DOS. In silabs.c the main function is
int64_t silab_cmd(int argc, char *const argv[])The first argv[0] is not really used by silab_cmd() but is there for simplicity in attaching this routine to a userspace
C main() function like this:
/* Example usage of silabs.c for realizing a userspace main() entry point */
int main(int argc, char *const argv[]) {
return silab_cmd(argc, argv);
}The rest of the args represent the commands and subcommands according to a grammar: (as of Jun 15, 2020).
help Print this help
status Print human-readable status
sleep <N> Enter uC sleep mode (low-power) for N millisec
reboot Power cycle and reboot both board and uC
wdog Exits errorlevel 1 if watchdog armed
wdog expired Exits errorlevel 1 if last reboot was from wdog
wdog set <N> Arms watchdog for N milliseconds
wdog feed Feeds watchdog
wdog disable Disables watchdog
scaps Exits errorlevel 1 if supercaps enabled
scaps enable Turns on supercaps for this boot
scaps disable Turns off supercaps for this boot
scaps default enable Sets supercaps to be default enabled on bootup
scaps default disable Sets supercaps to be default disabled on bootup
scaps current <N> Sets supercaps charging current in N milliamps
scaps current default <N> Sets default charging current to N milliamps
scaps wait Blocks until supercaps reach minimum charge
scaps wait full Blocks until supercaps reach max charge
scaps wait pct <N> Blocks until scaps reach (max-min)*N/100+min
scaps pct <N> Exits errorlevel 1 if scaps at N %
usb Exits errorlevel 1 if USB console connected
flags <N> Exits errorlevel 1 if uC flash flag N set
flags set <N> Sets uC flash flag N
flags clear <N> Clears uC flash flag N
fan enable Turns on fan
fan disable Turns off fan
For instance, to feed the watchdog using routines from silabs.c in your own application:
static const char *wdog_feed[] = {"silab", "wdog", "feed"};
silab_cmd(3, wdog_feed);The LISP routines are a work-in-progress but represent a LISP translation of the above silabs.c that also does a bit more. They require some additional quicklisp systems.
In silabs.c there is a porting layer consisting of 3 routines,
int8_t i2c_eeprom_read(uint8_t adr, uint16_t subadr, uint8_t *buf, int len);
int8_8 i2c_eeprom_write(uint8_t adr, uint16_t subadr, uint8_t *buf, int len);
int wait_hook(int); /* sleep for 100ms */
