Windows Software #5

Closed Primus007 closed 7 years ago

Primus007 commented 8 years ago

please can you or any other people suggest some windows software to compile and flash ??

a little how to for windows users would be nice too :+1:

many thanks for your work!

zerog2k commented 8 years ago

I only have mac and linux at the moment to develop on. But in theory for compilation sdcc is available for windows (might need a few makefile tweaks for windows paths, etc), and you can use the oem software (stc-isp) for flashing.

Primus007 commented 8 years ago

thank you. sdcc i a command line tool. anyone knows a gui for this?

currently i try Keil c51 to code/compile and make a hex file.

stc-isp i have downloaded. i have selected the STC15F204EA mcu. must i do some settings to work correctly? keil is missing some includes like stc12,stdint,stdio, where can i get it?

do you think i can use this module to connect to the clock P3.0 TX and P2.0 RX pin? http://www.aliexpress.com/item/FT232RL-FTDI-USB-to-TTL-Serial-Adapter-Module-for-Arduino-Mini-Port-3-3V-5V/2043815349.html

You might be able to use keil, but several things would have to be changed slightly. Most of the includes, e.g. stc12.h, etc. are written for sdcc. I think you also have to import the CDB for STC chips into keil (I think the stc-isp program provides this). There are a few differences here and there. Yes, sdcc is cli, but I guess you can incorporate it into an IDE of your choosing, e.g. netbeans, eclipse, etc - but that's a different topic altogether.

Regarding flash programming, it's always done over serial uart using the ROM bootloader onboard STC chips. On the clock kit, I soldered a header onto J1 (TXD/RXD/GND/VCC), and also pulled the leg of RST (pin 18?) up from socket and have that tied to a jumper which is hooked up to DTR pin (for managing reset/boot sequence in stcgal for programming convenience). I'm not sure if stc-isp uses dtr for reset into bootloader. May need to manually powercycle (vcc or gnd) when attempting download.

thanks for your answer!

I think you also have to import the CDB for STC chips into keil

yes that is right. but i cant find a CDB with the STC15F204EA. But i found a STC15F204EA.H file. i think this is ok also.

thanks for your help. i will try it in the next days and hope all gets well.

is it possible to get the original code from the clock? anywhere in the www to download?

Primus007 commented 8 years ago

ok i have now the software for windows "micro-ide" with sdd integrated. All works but there is a Problem by compiling ds1302.c see the attachment. please can you help me? thanks! ds1302

i think the problem are different stdio.h, stdint.h, stdlib.h, stc12.h files. can you upload your files?

zerog2k commented 8 years ago

are you compiling w/ sdcc or keil? (if sdcc, which version?)

(@jjmz did some code size optimization - which is highly "sdcc", e.g. calling pragmas, etc)

The line seems like valid C for right shifting... It's not immediately obvious what might be going on.

jjmz commented 8 years ago

Sorry if I broke something. That's true I am only using sdcc. Thus I hesitate issuing a PR, since my latest code is really "sdcc" & optimized... (2278 bytes, with seconds display & zeroing, MMDD/DDMM option for date display) but the code now greatly diverges from yours.

zerog2k commented 8 years ago

@jjmz no worries - this is a good thing... @Primus007 we can make sdcc vs keil preprocessor macro conditionals - this is how some SiLabs IDE MCU code (C8051F320 for example) does to manage multiple compilers. They use a compiler_defs.h to abstract and normalize compiler differences...

I see stuff like:

#if defined SDCC

#if (SDCC >= 300)
...

// Keil C51
// http://www.keil.com
#elif defined __C51__
...

You can see the full example of what they are doing here: https://gist.github.com/zerog2k/778af78a77c956eaafef94948853ef7e

Primus007 commented 8 years ago

currently i use this: Micro-IDE SDCC 8051 Development System http://www.bipom.com/products/us/319513.html there is SDCC 2.9.0 included. But i have the header files from the newest sdcc version for windows x64 v3.6.0

With Keil are more errors. with sdcc only the one seen in the screenshot.

zerog2k commented 8 years ago

yeah, sdcc < 3.0 is old. This was developed on 3.4 and 3.5. Latest is 3.6. I dont know anything about that IDE, but maybe you can re-point it to the newer sdcc toolchain. I'm guessing that will fix this particular issue.

Primus007 commented 8 years ago

thank you very much. it seems to work! I have now the .HEX file.

//Edit: there is one warning: ds1302.c Col 127: in function ds_writebyte unreferenced function argument: 'data'

Can i make a Backup from the current Clock before i upload the new .HEX or is the original .HEX anywhere to download?

zerog2k commented 8 years ago

regarding that error and your screenshot above, maybe you need to reset and resync to git... Looks like you are missing a line from the code base: https://github.com/zerog2k/stc_diyclock/blob/master/src/ds1302.c#L123

regarding backup - short answer - there is none. Long answer:

  1. this is a security "feature" of stc bootloader that you cannot download code from flash of a programmed mcu, and
  2. I have not seen anyone release the firmware (even in bin/hex) format of the original, although I suspect there might be some minor variations between kits in the wild.
