... Vasile Oops! I took the averaging routine out as it didn't stop the reading changing, but it considerably slowed the speedo's ability to change. Now that...
Hi wouter ... things in the ... Thanks for your reply, to use interrupts should i use the interrupt (assembler) example in my book "Easy PIC'n" or is there a...
Hmm. the trick was ADC conversion 32 us.And the other was that SPI is real fast compared to RS232 or I2C. Thanks, Jeethu Rao ... From: Javier Martinez...
Hi Jeethu, Microchip specs says about a 20us of adc conversion. The SPI & I2C are impemented in the same hw module (MSSP). Usually SPI works with CS (Chip...
Hi All Many people have been talking about interfacing to eeproms like the 24C01 etc... I have recently scawaged an old radio where i found a 24C04 which i...

Hi Lasse Try Phil's code first - it is in the files section on jallist. I personally did not have any success with it, but I believe it does work :-) I...
Hi all, Could someone please explain how the i2c routines supplied with JAL can be used to read the temperature from two LM75's. Are the SDA and SCL pins of ...

... yes, that is 'the i2c way' ... No, that would be more like SPI (shared clock/data, separate enable). Wouter van Ooijen Van Ooijen Technische Informatica:...
... What will be the length of the i2c bus? Better check the philips documentation for what is reasonable, i2c (and spi) are meant to connect IC's, not...
Hi all I have some buttons which prints some messages on a LCD display In order so save power the backlighter on the LCD module should turn off for instance...
Lasse, Unless you are just bound and determined to use a PIC for this, why not use a low-power 555 timer set for a 5 second delay, triggered by the key press,...
This is my first post here on the list... I just try to test some stuff with JAL to see how it works, I have made some program for flashing a LED and some...

Hi Vasile ... 100kHz i2c - that is what my datasheet says the max is for these 24cxx eeproms. If I change my internal wait for the i2c to less than 1ms, it...
Use the ADC to measure the resistance of the soil. You'll need a PIC 16f87x (the PICs with ADCs). Or maybe you could do it with the comparator of the 628. For...
I can see a few problems with your code. It looks like you're trying to use RB0 to detect the interrupt, but you're enabling the PORTB interrupt instead of...
