- Short: PIC16 development package
- Author: rdc@cyberstorm.mtu-net.ru (Denis I.Sotchenko)
- Uploader: rdc@cyberstorm.mtu-net.ru
- Version: 1.5
- Type: dev/cross
- Replaces: dev/cross/devpic.lha
-
- Current version of this package contains:
-
- picprog - my simple CLI-based PIC16 «development» programmer
- picasm - PIC12/16 assembler by Timo Rossi
- picreset - «in-circuit reset» tool
- picrecv - simple debugging tool for debug info printing
-
- All tools have full source code, ready for recompile.
- Binaries for 68000 included. You can recompile it for your CPU.
-
- Included picasm version has some differencies from original 1.06
- version: some bugfixes and full PIC12/16 line support (from Microchip
- Product Line Card 3Q1999). I do not guarantee correct fuses values,
- but current picprog anyway doesn't support fuses embedded in HEX file.
-
- 1.4+ devpic package contains also MS-DOS version of picasm - it was
- done because I'm currently occupied in commercial PIC16 development,
- and my boss want to have ability to compile my source code :) maybe
- it can be useful for similar purpose. picasm.com was compiled using
- free Turbo C 2.01 (http://www.borland.com), and works even on PC/XT.
-
- picprog supports all current PIC16 Flash microcontrollers: PIC16C8x,
- PIC16F8x, PIC16F62x, PIC16F87x. It was really tested and works with
- PIC16F84 and PIC16F876. It has intelligent programming algorithm -
- before location programming it will read old value and will program
- location only if it is different. As a result, programming of new
- version of code may take only some milliseconds.
-
- Additionally, picprog has SmartFlash algorithm, usable for new
- (PIC16F84A and others) Flash PICs. If it will be enabled, picprog
- reads all code in temporary buffer and calculates time for two
- programming modes: erase programming cycles, and bulk erase and
- programming only cycles (programming only cycle for 16F87x is 2ms,
- erase programming - 4ms). If there are only some differencies (for
- example, if you compile new version of code with only one new
- constant), erase programming cycle will be performed. If there are
- MANY differencies (new commands at begin of program), picprog will
- erase all code (Bulk Erase command) and program chip by faster
- Programming Only commands.
-
- At result, v1.2+ picprog may program new Flash PIC16 up to 5 (five)
- times faster than old picprog and some other programmers.
-
-
- PicProg usage:
-
- picprog FILE [FORCE=xxxx] [CONFIGWORD=xxxx] [VERIFY] [SMARTFLASH=n]
-
- FILE - object file in Intel Hex format, generated by picasm or
- any other PIC assembler.
- FORCE - remove code protection with erase all code and data.
- This configuration word will be written BEFORE code
- programming and must not contain code protecting bits -
- because code may be written only without code protecting.
- CONFIGWORD - this configuration word will be written after programming
- of code. It is the only way to do code protect.
- SMARTFLASH - enables SmartFlash algorithm as described above.
- Argument is number of milliseconds required for
- Programming Only cycle (5ms for PIC16F8xA, 2ms for
- PIC16F62x and PIC16F87x).
- SmartFlash DOES NOT WORK WITH PIC16C84 and PIC16F84!
- VERIFY - additional verify cycle for better reliability.
-
- Configuration word must be entered in decimal form. You can find
- configuration word formats in PIC programming specifications may be
- found on Microchip website or free Microchip Technical Library CD-ROM.
-
-
- WARNING: picprog from version 1.3 has new version of hardware! New
- hardware doesn't require manual switching of 12v programming voltage,
- and does it automatically. New hardware is similar to old, and you
- can «upgrade» your old Epic programmer hardware. But you aren't
- forced to do it - new picprog is fully compatible with old hardware.
- Version 1.4 introduces v2 of hardware - optional diode for PIC16F84
- in-circuit programming added. It is not required in any other cases.
-
- Some notes about hardware: I don't know non-exUSSR equivalents of used
- diodes and transistors. Probably, you can use any existing silicon ones.
-
-
- Notes about In-Circuit Programming: picprog allows to prorgam PIC
- even in circuit, without removal from socket. For using of this
- feature you must develop your circuit with following rules:
- - MCLR must be connected only with programmer - you can connect it
- with +5v or reset scheme, supervisor, etc - after development
- - usage of RB6 and RB7 are not recommended.
- - PIC16F84 may be programmed incorrect, because of working internal
- clock generator - internal programming logic of C84 and F84 shares
- one program counter with CPU, and if quartz or RC generator was
- started in programming mode and counts more than 72 cycles, program
- will be written to wrong addresses. devpic hardware v2 introduces
- new optional circuit (see scheme) that can be connected to OSC1
- (pin 16), and it will flush generation during programming. Newer
- Flash PIC16 devices do not require this.
-
- (Note: diode must be placed on PIC side, not on programmer side)
-
-
- PicRecv usage: simply start it and it will receive debug info.
- For detailed info see debug info sending sample - source/picsend.asm.
- PicRecv requires in-circuit programmer connection. CTRL/C - exit from
- picrecv, CTRL/D resets PIC.
-
- Note: both picprog and picrecv own parallel port and can't be started
- simultaneously!
-
-
- PicAsm usage: included picasm package contains it's own documentation.
-
-
- All programs are tested and works ok with my current Amiga setup:
-
- A1200 Magic (ESCOM) in Slim case
- A3000 external keyboard
- Chinon FZ-357A HD floppy from A4000
- 35Mb RAM - 2chip, 32+1fast
- Blizzard 1260, overclocked to 59MHz
- Blizzard SCSI Kit
- Seagate Barracuda ST32171N 2Gb, Fast SCSI-2, 9.2Mb/s
- Quantum Fireball TM3840A 3.6Gb, IDE
- Selfmade IDE accelerator (up to 5Mb/s)
- Panasonic CR-572B 2x, IDE
- Multitech MT2834ZDX, 28.8
- «Microvitec with DMS» 12" digital multisync
- CNet CN40BC 10Mbit combo PCMCIA Ethernet card
- Selfmade PIC-based PS/2 mouse controller and DATACOM PS/2 mouse
- POWERCOM UPS-400-A
- HP LaserJet 5L (manually exchanged with picprog if needed)
-
-
- System requirenents: OS 2.x (maybe - not tested yet)
