Hi Kyle, I've tried it and is seems to work: declaring and using an alias for a pseudo-variable. But just to make sure, is this 'legal'? Regards, Rob. -- Rob...

Have forgotten to say that the hardware I use can be find on : http://www.cc5x.de/MMC/index.html The publisher of this info agrees with my attempts to use it...
Hi Kyle, [RobH] ... [Kyle] ... Some background info for my question: Some PICs (esp. in the baseline) have no memory mapped TRISIO register. So it is not...
... If I had found your libs earlier then I would certainly hooked in on yours, but since I am now so far that my little attempt works (and is more than...
Is it possible to use program memory for variables? or to store data that was retrieved from an external source? I need somewhere to store sector data from a...
Look at my program, I use Program_Eeprom_write(or read) (adress,data) start adress from 7500 to 8012 I use the remaining 80 adresses for other info. Hans...
... Why not switch to a PIC of the 18F series? The 18F14k50 for example has 768 bytes of RAM, or if you need more pins the 18F2450 or 18F4450. You'll get also...

... The "wear out " is not true, see: http://mientki.ruhosting.nl/data_www/pic/libs_hw/eeprom_problems.html indeed the EEprom is slow fro writing, but not for...
[Default] On Tue, 7 Jul 2009 13:27:25 +0200, Stef Mientki ... That page discusses EEPROM, not program memory, but maybe they are the same? I am not sure I...
Hello, I'm trying to make a decoder in JAL, but the interrupt service routine has to be extremely short. When I write a normal interrupt routine using 'pragma...
Hello, I am trying to read a potentiometer more precisely. The pot is made by Bourn, 10K and 15 turn. I only need 2-3 turns while with accurate readings. The...
Hi Helge, ... It has, the 16F877 datasheet (page 156) is clear enough about this: Program FLASH memory parameter D130 Endurance 1000 kind regards, Hans de...
Have a look on the web for "resistor voltage divider" to give you the ref voltage that you need. Depending on the resistors that you select you will get a...
I think Kyle was going to add some other interrupt pragmas for no preamble. Check the latest version of the manual and test to see if they work. Be careful...
... I think you're right, the newer (self programming) devices have a very small number of erase/write cycli. cheers, Stef ... Het UMC St Radboud staat...
I wish I could understand this discussion. Reading on page 156 from my datasheet I see other things than mentioned. Do I have the wrong sheet?(Microchip...
Greetings, ... How are you restoring in less than 5 instructions, or do you not count the retfie? The best you can do at the moment is `pragma interrupt fast'...
Because of no reactions I suppose my questioning is incorrect. I'll try it this way : Does the use of the commands " Program_EEprom_write(Adress,Data) and...
... That depends on how often you use them. Details (guranteed nunber of erase/write cycles) can be found in the chip's datasheet. -- Wouter van Ooijen --...
From 16F877 Datasheet: "The EEPROM Data memory is rated for high erase/ write cycles (specification D120). The FLASH program memory is rated much lower...
... I use the external ram chip: http://www.voti.nl/winkel/catalog.html?IC-23K256-DIP. For sequential read or write (which do not allow the address to be sent...
... Microchips guarantees a minimum number of programming cycles, and this has the same impact as programming the PIC. I have to say I've never ever had a worn...
... Patience, patience. We do have a life you know ;) I was talking about the 16F877 datasheet. In the 16F877A datasheet you will have to look at page 179, ...
Hello, I'm a beginner on JAL and have a problem. How can I use the Analog inputs (A0..A5, E1..E3) as digital. I'm working with a PIC16F877 and the 16f877_bert...
