Note that this changes the + names of the symbols in the generated C program; so a system that + uses "magic variables" with this target for I/O must be updated + to use the new names. + + * Fix a subtle bug in the PIC16 add and subtract routines, where + operations of the form B = A - B could fail. + + * The piecewise linear tables were broken for the AVRs; fix that. + +== Release 2.1 + + * For the AVR UARTs, poll UDRE instead of TXC. The formatted string op + was broken on some targets, should now be fixed. + + * Don't draw selected op in bold font; that looks ugly under Vista. + +== Release 2.0 + + * Add PIC16F886 and PIC16F887 targets. + + * Fix display bug in the list to select an I/O pin. + + * Fix bug where PIC16 UART locks up forever after a framing error when + the cycle time is faster than one byte time. + + * Fix bug where PIC16 outputs could briefly glitch high at startup. + + * Clear PCLATH in PIC16 boot vector, since some bootloaders expect that. + +== Release 1.9 + + * Modify PIC16 boot vectors to work with many bootloaders. + +== Release 1.8 + + * Fix modification of a constant string that blew up in new MSVC++ + compiler. + + * Add Italian, Turkish, Portuguese. + +== Release 1.7 + + * Make the source compile with latest version of MSVC++; overloaded + functions behave a bit differently. + + * Recover from (and ignore) UART errors on the PIC16 target, instead + of getting stuck forever. + + * Whenever contacts bound to an output pin (Yfoo) were edited, they + reverted to an input pin (Xfoo); now fixed. + + * Don't abort on too-wide program; instead display nice message. + + * It was possible (by adding and deleting contacts/coils with the + same name) to end up with two bit variables bound to the same + physical I/O pin; now fixed. + + * File -> Open was correct, but Ctrl+O failed to ask about unsaved + changes before opening requested file; now both are correct. + + * Add Spanish user interface strings. + +== Release 1.6 + + * Internationalize the user interface strings; we now have versions + in English, French, and German. + + * First source release, under the GPLv3. + +== Release 1.5 + + * Add untested support for ATmega32. + + * Remove annoying lag in user interface when editing large (hundreds + of ops) programs + +== Release 1.4 + + * Fix a terrible bug in the target for the ATmega8; because there is + no PORTA/DDRA/PINA, I broke an assumption in my code and failed + to set up the port directions. + +== Release 1.3 + + * Timer delays are represented as a signed 32-bit integer count + of microseconds. If the user provides a delay >= 2**31 us, then + show an error instead of just letting things wrap. + + * Change the start-up behaviour of TOF timers. Previously they would + start from a count of zero, so they would be on (independent of + rung-in) until they counted themselves off. Now they start out + at full count (as if rung-in has been low for a very long time), + so rung-out is low until rung-in goes high. + +== Release 1.2 + + * Add an untested target for the ATmega8 + + * Add a special instruction to simplify piecewise linear tables + + * Fix some user interface bugs: it was possible to drag the top of the + I/O list so high that you couldn't grab it again, and there were + some cases in which the pin number associated with UART and PWM + variables was not displayed + +== Release 1.1 + + * Fix persistent variables, which were broken for the PIC16F628 + +== Release 1.0 + + * Fix bug in which the filename that appears in the title bar of the + main window failed to get updated when opening/saving a file using + the keyboard shortcuts (Ctrl+O/+S) + + * Fix simulation crash when the ladder logic program divides by zero + + * Fix jumpy scrolling on programs with many rungs of logic when the + cursor is off-screen + +== Release 0.9 + + * Fix bug with formatted string op on the AVR + * Fix previously-untested ATmega16 and ATmega162 targets, which were + completely broken + +=== Release 0.8 + + * Fix PORTA on the PIC16F819 (came up assigned to ADCs, of course) + +=== Release 0.7 + + * Support arbitrary character (\xAB) escapes in formatted string op + * Fix a bug in which the title bar of the main window was not updated + +=== Release 0.6 + + * Add formatted text output over serial (e.g. to an LCD or a PC) + * Add ability to make variables persistent (i.e. auto-saved in EEPROM) + * Add look-up table instructions + * Fix a bug with the PORTE pins on some AVRs + * Fix miscellaneous user interface bugs + +=== Release 0.5 + + * Interpretable byte code target + * Shift register and master control relay instructions + +=== Release 0.4 + + * Make ADCs work on the AVRs + +=== Release 0.3 + + * Support serial for AVR + * Support PWM for PIC16 and AVR + * Show program filename in title bar of main window + * Untested support for PIC16F88, F819, F876 + * Generate ANSI C code from ladder diagram + +=== Release 0.2 + + * Support serial communications (using UART), PIC16 only + * Support ADC reads, PIC16 only + * Simulation environment for ADC and serial + * Support ASCII character constant ('a') literals + * Fix PORTA pins in PIC16F628 (should assign as GPIO, not to comparator) + * Make file open/save dialogs work under Win98 + * Fix PORTA/PORTE pins in PIC16F877 (should assign as GPIO, not to ADC) + * Add ability to comment your program + * Fix bug when a relative filename is given on the command line and + the `Compile As' dialog is later used to specify a destination in + a different directory + +=== Release 0.1 + + Initial release |
