Continuing -
Behavior repeats:
Code:
241.36°C 2821720
241.36°C 2821730
[B] 2 // This char was ON THE SerMon but not copied [/B]
Close tSerMon and Restart - with increment to '3'TEMP - but first lines are those from PRIOR:
Code:
41.36°C 2827892
241.36°C 2827902
241.36°C 2827912
2 skW:345938
40.70°C 6287302
340.70°C 6287312
340.70°C 6287322
340.70°C 6287332
...
Altered
BOLD part of the code and now the LED is showing the delay(10) PULSE.
But the other two added lines are not helping Just added an extra set - RED. Restarted after upload and
accidentally hit ENTER/Send in SerMon right away - which would be ignored until .available() is <40. It quickly triggered:
Code:
40.70°C 45882
40.70°C 45892
[B]skW:1[/B]
40.70°C 45972
1 40.70°C 45982
1 40.70°C 45992
1 40.70°C 46002
I have hit 'Send' again and still running. without triggering the '1' (now left of TAB) to go to '2'.
WELL : it just Stalled again? The .read() did not help adjusting the USB buffers available by freeing one when the char was read.
Doing tSerMon close and restart begins:
Code:
41.36°C 604422
1 40.70°C 604432
1 41.36°C 604442
1 [B]skW:3160[/B]
41.36°C 667852
2 41.36°C 667862
2 41.36°C 667872
...
After that tSerMon restart it ran for some time and stopped as:
Code:
2 41.36°C 1214249
2 41.36°C 1214259
2 skW:1
41.36°C 1214289
3 41.36°C 1214299
3 41.36°C 1214309
...
3 41.36°C 1237337
3 41.36°C 1237347
3 40.70°C 1237357
3
and again:
Code:
...
41.36°C 1243519
3 41.36°C 1243529
3 41.36°C 1243539
3 skW:33739
41.36°C 1918429
4 40.70°C 1918439
4 40.70°C 1918449
...
So something is going on with the Host/tSerMon side and have not found a 'sketch' way to avoid or correct::
Code:
// https://forum.pjrc.com/threads/68199-Teensy-4-1-Lockup?p=288611&viewfull=1#post288611
void setup() {
Serial.begin(115200);
Serial.println("\n" __FILE__ " " __DATE__ " " __TIME__);
while (!Serial) {}
pinMode( 13, OUTPUT );
}
uint32_t writeSkip = 0;
uint32_t skipLog = 0;
void loop() {
if ( Serial.availableForWrite() > 40 ) {
if ( writeSkip > 0) {
Serial.print("\t\tskW:");
Serial.println(writeSkip);
writeSkip = 0;
skipLog++;
}
Serial.print( tempmonGetTemp() );
Serial.print("°C");
Serial.print("\t");
Serial.println(millis());
if ( skipLog ) {
Serial.print(skipLog);
Serial.print("\t");
}
}
else {
writeSkip++;
[B] if ( Serial.available() ) {
[B][COLOR="#FF0000"] Serial.read();
delay(50);
[/COLOR] }
Serial.flush();
delay(10);[/B]
[/B] }
delay(10);
digitalToggleFast( 13 ) ;
}
For Reference just put same code on a second T_4.1 (no pins or heat sink, and twin PSRAM's) and it is running with TyCommander as SerMon - expect it will run fine forever with NO similar behavioral issues ... Time will tell ... As of now it shows:
Code:
C:\T_Drive\tCode\Serial\SerialTestBT\SerialTestBT.ino Sep 16 2021 12:21:24

1 47.67°C 7234586 // Still running - no more skW==writeSkip or associated : skipLog++

>> That "skW:1" does show it dropped TWO prints of 10ms - one because of the delay(10);
<EDIT>: Since tSerMon was repeatedly failing the same way even with restarting ... and TyComm shows no propensity to Stall I did a quick EDIT to see if it changes anything::
>> Duplicated the core code and Variables going to Serial and Compiled 528 MHz with Dual Serial with all prints and tests referring to : SerialUSB1. and writeSkip2 and skipLog2
-> just about to point of prior failures - but nothing but normal prints so far ... at 500 Seconds
