PSoC™ 5, 3 & 1 Forum Discussions

 Hi all,

I managed to short Vin to ground while I had a 12v supply hooked up to the barrel plug on my board. No magic smoke came out of any of the chips (that I saw), but my board no longer works. When the j10 jumper is set to 3.3v the 3.3v regulator just above it gets rather hot (might burn me if I left it on). Also my VDDD has continuity to VSSD (ie, it's shorted to ground) when j10 is in any position (including not attached). I would geuss my 3.3v regulator was blown, but it's doing its job just fine (tested with a mulitmeter and I get 3.3v on the middle pin and the big tab). I also checked  and confirmed that the caps in the power supply circuitry don't have continuity to gound. Any ideas on what to check next? or where I can buy another dev kit (everyone seems to be out of stock)?

Thanks,

Geoff

Is it possible to wake from sleep then:

1. Power up the ADC and OpAmps

2. Start a conversion

3. Power up the DFB

4. Pass the ADC sample to the DFB

5. Output the previous DFB result via I2C

6. Go back to sleep

All at 9ksps ?

I have severe power limitations!

Thanks,

Richard

 I have warnings saying "Multiple  call Start/Main Interupt/ISR" what is this warning saying and how to remove this.

I have this function called 'Start" which I am using in main as well as one of the interrupt routine. What has to be done to remove this warning

Dear all CDC members

I am designing and planning to implement SDR(software defined radio) on PSoC 001 Kit.

Please help me out for this project by posting sample projects and tips.
