Re: Any restrictions for Pin 33, 34 or 35 ?

Thanks Daniel We decided to not use pin 33,34,35, they are now floating, I changed the layout on my prototype to avoid them so there is no issue for me any longer. It seems to be pin 33 or 34 that give problems on power up , but I don't have time to dig in to it Note: My Basic program do not hang, i...

Any restrictions for Pin 33, 34 or 35 ?

Hi I get a strange behavior when I connect pin 33 to a ULN2003 driver input. The autostart led stops flash on powerup and the yellow led lights up steady, the RTC resets and the connection to PC fails. The nominal load on pin is 2.7 Kohm from ULN2003 Other pins 29-32 work fine when connected to ULN ...

Re: SERBNG Command ????

Thank you Daniel
Ver 0.78 installed and SERBNG verified for pin 25 to 30 to work flawless in 9600 baud. :D :D

SERBNG Command ????

Hi I try to understand how the SERBNG command works, I try to use the Command in the way it is descibed in the user manual (I think I do) to send a string on pin 30. My intention is to output a short string to a serial display on pin 30...9600 baud (logical 3.3 V level output) example: pinmode 30, o...

Re: How to store/read numerical parameters from EEPROM ?

A comment only, the exemple-code can store any decimal number within -9999999 to 9999999 and is not limited to integers only, the stringlenght is fixed and is allways 8 characters including sign and any decimalpoint. ( a parameter can hold: 0.34, 3.14267, -9.12345, 0, -0.00001 or 9999999...) :idea: ...

Re: How to store/read numerical parameters from EEPROM ?

Thanks to Daniels great support do we now have a working solution to store/restore a lot of parameters on EEPROM. :D :D There are anyhow some critera to keep in mind..... 1. A string is not allowed to cross the page boundary on the EEPROM used (boundary bug in EEPROM), control that the string fit in...

Re: How to store/read numerical parameters from EEPROM ?

Thank you Andries, your code was helpfull, it saved me a lot of work :D . My controller has now arrived and I was able to test my code package for save and restore integer data on EEPROM and everything works fine. I will post the code when I know how to do it. I set the resolution in the conversion ...

Re: How to store/read numerical parameters from EEPROM ?

Hi Daniel After that I have reading the manual and the list of commands several times is my own conclusion that I strongly believe that there are no direct command to, in an easy way, read/write a 32 bit parameter to and from an external EEPROM (Please correct me if I am wrong). My conclusion is tha...

Re: How to store/read numerical parameters from EEPROM ?

Thank you for Your fast feedback There are no particular EEPROM selected so I can use any type that You propose and that will work well. I need to store parameters for calibration, setpoint, position, speed and so on... and they can be scaled to be 32 bit integers. I assume that its a common need fo...

How to store/read numerical parameters from EEPROM ?

Hi Is there any way or method to store/read up to 20 unsigned numbers in the internal EEPROM area (4k) or to add an external flashmemory for storage. I need to save 20 parameters before power down and reload them at next power up. This must be under control of the basicprogram and not limited to pre...
