Re:Problemi di Frequenza

Se ho capito bene, la situazione è: - il led è acceso da un task - il task è attivato ogni 20 ms - aggiungendo del codice al task il led non si accende più periodicamente Allora una possibile causa potrebbe essere il task che dura più dei 20ms. Inoltre, installate la patch del kernel ...

Re:Problemi di Frequenza

Ok... (in effetti non mi ricordavo di aver mai pubblicato una temporizzazione a 20MHz per la Flex...)

Re:Problemi di Frequenza

Su un esempio del manuale si imposta il periodo di timer1 a 1 ms avendo una Fosc=20Mhz, che diventa quindi 5000 (decimale). Come si passa da 20MHz a 1388? (non ho trovato questo esempio all\'interno dei manuali di ERIKA... a che pagina si trova?) 5000 decimale = 0x1388 (esadecimale) (per fare la pr...

Re:Problemi di Frequenza

Ciao, No, non ci sono stati cambiamenti nel codice. Prova a ripartire dal demo più semplice, quello con il pask periodico. su quello la frequenza è sicuramente corretta. Inoltre fai attenzione al fatto che la frequenza va specificata in 2 punti, la prima all\'inizio del main con quel ciclo inf...

Patch released for ERIKA Enterprise

Dear All,

We just released a patch to fix a bug on interrupt disabling and to add some SPI functions used in the USB application note. You can find it into the ERIKA download page for dspic.

bye,

Re:Problemi di Frequenza

Si, mi ricordavo che l\'esapode nella versione iniziale usava i primi prototipi della Flex... Da quello che so i due chip dovrebbero essere uguali a parte qualche periferica. In ogni caso dovrebbe essere impossibile programmare i due chip conlo -stesso- binario... come hai fatto? l\'ICD2 se non sbag...

Re:Problemi di Frequenza

Ciao!

Intendi dire che lo stesso ELF file programmato sulle due board da un risultato diverso? Mi sembra abbastanza strano, dal momento che i chip dsPIC utilizzati sulle due schede sono identici. per caso hai delle schede di prototipazione con il chip versione GP e non MC?

Ciao,

Paolo

USB connection between PC and Flex Full

Dear All, we just released an application note on how to connect the FLEX Full to a PC using USB, providing a software example for both the dsPIC and the PIC18 on the board... This is just the start, the next steps will be the integration of the SPI primitives in ERIKA and then the Scilab/Scicos sup...

Hi David, This is quite strange... and it\'s the first time I see it... basically the line which is failing in the script is the following: export EE_INSTALLDIR=`cygpath -ms \\`reg query HKEY_LOCAL_MACHINE\\\\\\\\\\\\\\\\SOFTWARE\\\\\\\\\\\\\\\\Evidence /v EE_InstallPath | awk \'/EE_InstallPath/{ pr...

Re:Scicos_pack

Dear peter, yes, you can use the Scilab pack V5.2 (which was a bug fixing over the original V5). And yes, it is possible to make the system working for smaller PICs, like PIC24 and others. In fact, ERIKA already works for PIC24, and we have done some tests over the Explorer 16 board. Apropos the Sci...

Re:can not fined PIC 30 .elf File

Dear Peter, The ELF file has not been produced because RT-Druid (and then the generated makefile) could not find your C30 compiler. Please take a look at the Erika Enterprise Tutorial for dsPIC (R) DSC 30 family v. 1.1.9 , available for download at http://www.evidence.eu.com/content/view/185/219/ . ...
