Heads-up: PIC16F1773 header correction

There seems to be a mixup in pic16f1773.inc. ODCONA bitfield definitions seem fine. However, several ODCONB bitfield definitions are misnamed as a mix of "A" and "B", such asODCONB_ODA0_POSN equ 0000hIn addition, there are eight bit register definitions missing from this list:#define ODA4 BANKMASK(O..

Another serious pic-as shortcoming?

I have never, ever heard of that before.So I asked the support folks if there is a way to define a string (like a text message) in pic-as source code an..

Bug in #define in pic-as

I found that in pic-as when you do a statement like this: #define abc MyByte,MyBit ; Comment When you use 'abc' what it inserts is 'MyByte,MyBit ; Comment'In other words, the ;Comment part is a part of the replacement text!This normally doesn't make a problem because the extra junk is in a comment a..

Unable to read internal EEPROM or modify NVM registers

I am using a pic16lf19197, version 5.40 of MPLAB X IDE, and version 2.2 of the xc8 compiler. I am using the __eeprom qualifier to define a structure in the EEPROM memory and I can read that out using the MPLAB IDE, so data appears to be getting written to the EEPROM and MPLAB is able to read it usin..

Free XC8 for WIndows 7 32bit?

Like most hard core EE's my laptop is full of highly useful apps that won't run on 64bit or Windows 10 for that matter. I am not an IT jockey who believes the world will end if I don't have the very latest OS installed on my computer. Is there are free version of the XC8 C compiler that will work on..
