For the PIC microcontroller's I prefer to work in assembly, however I am have issues setting it up. I installed MPLAB X IDE 6.15 and read that it doesn't come with any toolchains pre-installed and I am trying to figure out how to install the assembly toolchain. I downloaded a version of mpasm (from Microchip's website), however it doesn't work.
COBOL really only has two data types: Numbers and strings. The layout of each field in a COBOL record is precisely specified by a PICTURE (usually abbreviated PIC) clause. The most common ones are: PIC X for strings. PIC X(100) means a 100-byte string. PIC 9 for numbers, optionally with S (sign) or V (implicit decimal point). For example, PIC S9(7)V99 means a signed number with 7 digits to the ...
When programming my PIC18F6722 using MPLAB IDE v8.91 (the 32bit version), my PIC works and starts successfully, but when I use the HEX generated from MPLAB IDE, but program it using MPLAB X IPE, the programming part is successful, but my PIC does not start up.
Programming HEX using MPLAB X IPE v6.15, leads to PIC not starting
I know it is a different PIC, but for PIC33EP256MU806 an obscure section "11.5 I/O Helpful Tips" of the datasheet says: "The internal pull-up is up to ~ (VDD-0.8), not VDD. This value is still above the minimum VIH of CMOS and TTL devices." This is not mentioned elsewhere and I actually measure VDD - 1.2V. So maybe this is normal behaviour for weak pull ups.
