Post STM8S103F3 Development Board (HCDVBD0034)
Image




This development/breakout board (HCDVBD0034) is based around the ST Microelectronics S103F3P6 microcontroller. STM8 microcontrollers are an ultra low cost solution to embedded control. This development board provides convenient access to the devices I/O pins via standard 2.54mm pitch headers (require soldering). Besides providing access to most of the microcontrollers I/O, there is additionally a microUSB connector for powering from a USB port, and a standard ST SWIM programming/emulation header that allows for programming or debugging using a compatible programmer such as our low cost ST-Link compatible USB programmer (HCDVBD0016). An on-board 3.3V regulator provides power to the board supplied via the 5V USB or 5V header pins. The ST tool chain (STVD) is available as a free download from the ST website and is fully compatible with this board. There are also additional third party tools such as the Cosmos ANSI C compiler (8K limited) and the SDCC (Small Device C Compiler) which can be downloaded for free. Links to these tools are provided at the bottom of this post.

Post Re: STM8103F3 Development Board (HCDVBD0034)
With a RaspberryPi 3 (Now works on a PI Zero W) I have had some success reading the flash and eeprom.
The part number is actually STM8 S 103F3 :oops:

sudo apt-get update
sudo apt-get install -y sdcc screen picocom minicom
sdcc --version

SDCC : mcs51/z80/z180/r2k/r3ka/gbz80/tlcs90/ds390/TININative/ds400/hc08/s08/stm8 3.4.0 #8981 (Jul 11 2014) (Linux)

git clone https://github.com/vdudouyt/stm8flash.git
cd ~/stm8flash/
sudo make
sudo make install
sudo apt-get install libusb-1.0-0.dev
ls /usr/bin/stm8flash //to know where the executable lives

//Always ensure that you do not trash your source file as reading will over-write it. ie. keep backups out of the current directory.

//The next sample lines reads -r the 8K flash and 640 byte eeprom using ST-LINK V2 programmer SWIM
sudo ./stm8flash -c stlinkv2 -p stm8s103?3 -s flash -r flashfilename.hex
sudo ./stm8flash -c stlinkv2 -p stm8s103?3 -s eeprom -r eepromfilename.bin

MINDEV is the miniature development system.
Get MINDEV.ihx from https://github.com/TG9541/stm8ef/releases as file stm8ef-bin.2.2.10.zip

//This writes -w the stm8S with the Forth OS.
Code:
sudo ./stm8flash -c stlinkv2 -p stm8s103?3 -s flash -w MINDEV.ihx


//Now pull the stlinkv2 programmer and disconnect.

//eForth is now operational! from a RaspberyPi3 or Pi Zero W, using mini-USB as 5 volt power and an HC UART dongle for communications; PD5 Green PC-RXD, PD6 White PC-TXD, Black ground of course. Red +5 v is left unconnected for now until I confirm VDD pinouts.
screen or picocom are USB terminals.
dmesg to see which USB port is active after plugging dongle in.
usb 1-1.2.3: pl2303 converter now attached to ttyUSB0

screen /dev/ttyUSB0 9600 //screen is installed with sudo apt-get install -y screen if it won't connect then pull the USB dongle and try again with dmesg | tail

The WORD square is volatile in RAM. COLD re-initializes the sysytem, stops running background tasks, and clears any words in Ram. RESET erases all added words in flash and RAM.
To put it in Non-Volatile-Memory:
Code:
NVM
: crlf EMIT 10 EMIT 13 ;
: square DUP * . ;
: cube DUP DUP * * . ;
RAM
- switch back to run mode. This code will survive a power cycle as it is now burned into flash.

10 square <enter> 100 ok
COLD
9 square 81 ok
10 cube 1000 ok
See that your added words survive a COLD restart.

WORDS -lists all words - system words historically in uppercase, so added words best to be in lowercase for visibility, but who cares! eForth doesn't

The core functionality of eForth began with 31 primitive words. The rest were compiled with the : - - - ; constructs.

Dumping the contents of memory is easy: Switch to HEX, enter start address, number of bytes and DUMP

FILE and HAND switch in and out of interactive mode and handle file transfers better? - yes by turning off local echo including error msg.
Blink LED PB5 in the background: 128 is $80 is 080 Hex
Code:
FILE
: blinktask TIM 128 AND IF 1 ELSE 0 THEN OUT! ;
HAND

' blinktask BG !

Crtl-h is the backspace.

The code mentioned elsewhere is more elegant and the hex value 0B ( 0000 1011 ) has inactive bits (low turns on the LED) and
I think that this is a way to run PWM in the background. Multitasking is not a feature but a simple hardware background task is.

Code:
: blinky TIM $0B AND 0= OUT! ;
' blinky BG !
0 BG ! //to stop flashing

The 8 K flash is taken up with < 5 K eForth OS. This leaves a lot of room for expansion. The MINDEV.ihx file on a Pi equates to
Code:
wc MINDEV.ihx
  158   158 11846 MINDEV.ihx
on eForth the true beauty and simplicity of Reverse Polish Notation is inherent when compared to CAS
( 11846 - ( 158 * 12 ) ) / 2 = 4975
Code:
 11846 158 12 * - 2/ . <enter> 4975

: intelhex 12 * - 2/ . ;
11846 158 intelhex 4975 ok
bytes using eForth

Rosetta spacecraft and Philae lander were launched in 2004 and arrived at Comet 67/P 10 years later. Both had significant instrumentation running on Forth. This alone is reason enough to abandon Windows / Mac and get with the 70's.

My dislike (hatred is more accurate) of Windows should not deter anyone from using the HC links and ST Microelectronics IDE and software, third-party tools, even HyperTerm or Putty. Putting an Airbus A380 cockpit on the back of a mosquito and saying how much you like flying is only meant to get more people back from the Dark Side. By all means, buy a board and interface and programmer from HC and learn Forth.

There are now many active eForth / STM8S parallel threads using different boards with supplemental information. Check for content from May 2017.

Barewires, that looks cool! So SDDC and STM8FLASH actually run on a RaspPi? This means that people with a Windows PC should have no problems using the embedded STM8 Forth on the github site (just use a RasPi)!

Thinking about it, boards like the HCDVBD0034 are a good choice for RaspPi I/O expansion, or as a system watchdog. Compared with an Arduino IDE the Forth is a featherweight - no need to run edit-compile-flash loops :-) Building an interfacing between the STM8 and the RaspPi through SPI or I2C should also be possible.

I do most of my development (well everything now) on a Pi 3 and the old / new - Pi Zero / Pi Zero W :idea: . I don't use Windows much as I need a reliable and consistent environment which sadly has never happened with MS. I have lost too much time and effort, since the 1985 Windows 1.0, watching that soothing Blue Screen of Death.

Feb 3, 1976 http://www.lettersofnote.com/2009/10/mo ... tware.html Bill Gates tried to take the moral high-ground after stealing time on a military-owned DEC PDP-10 system at Harvard and stole / disassembled / modified the Digital Equipment Corporation BASIC IP software contained on the university system to launch his company for personal gain. Even worse was his friend Paul Allen was not registered there and was accessing the computer. Bad, as Trump would say.

https://www.xkcd.com/378/ or https://www.explainxkcd.com/wiki/index. ... rogrammers if you don't understand it.
https://www.cs.utah.edu/~elb/folklore/mel.html

Real programmers, in my day, didn't have keyboards or monitors. Computers then 12 bit, 4K core, the price of a new house or two were incapable of making a mistake and then along came HAL 9000 and Mr. Bill. There just is not enough time left to start learning a new IDE having wasted much time on Microchip MPLAB over the years. I loved PICs since the 90s and even GCB recommended by HC is a cool free compiler. Using a PIC means buying programmers / development kits, which the ones from HC are perfect. The ease of eForth on an STM8S as a self-contained OS, interpreter, compiler, debugger for a few £ and makes everything else obsolete.

There are Windows options; SDCC, PUTTY, TeraTerm communications works with my eForth STM8S. I am sure that there are tools to do it but I am not going there.

Anything is possible with these parts. FORTH actually began in the late 60s and there are only a few languages that survive today. FORTRAN still is used in science, BASIC had a bad rap but is now a real high-level language (GCB Great Cow BASIC.) Arduino, I have a dozen, never rang my chimes, as I felt the edit-compile-flash-test loop was a step back to the 70s when UV erasing and burning EPROMS was the task if one couldn't afford a $25,000 Intel Development System.

Needing a variable frequency beeper, I found this works perfectly as a built-in hardware feature on the STM8S series.

https://github.com/TG9541/stm8ef/wiki/Board-W1401

Save the contents below in a file called beeper.f From the eForth command line in picocom do ctrl-A, ctrl-S (for save) and the filename ~/Desktop/beeper.f

NVM
FILE
: BEEP_CSR $50F3 ;
: beep BEEP_CSR C! ;
: beepA0 $A0 OR BEEP_CSR C! ; \ this defaults with bit7 set / bit6 reset and BEEPEN enabled - see later posts
: annoyA0 TIM 100 / 10 MOD 20 + beepA0 ;
: silence 0 BG ! 31 beep ;
: silenceA0 0 BG ! 31 beepA0 ;
\ ' annoyA0 BG !
\ ' annoy BG !
HAND
RAM

' annoy BG ! sweeps the BEEP pin Port D4 from 32.24 KHz down to around 2 KHz and loops over 21 seconds. Frequencies will vary slightly between devices. BG is a background task.
silence doesn't but hangs at constant 3.39 kHz = 17 beep, so it needs fixing.
The beep control status register is $50F3 and takes a range from 0 to $1e and is reset to $1f on powerup or reset press.
en.CD00190271.pdf is the factory manual.

Sample Beep Frequencies vary due to main osc variation:
0 beep \ <always hit enter> 32.24 kHz maximum
1 beep \ 21.5 kHz
2 beep \ 16.12 kHz
4 beep \ 10.75 kHz
8 beep \ 6.44 kHz
16 beep \ 3.58 kHz
17 beep \ 3.39 kHz
20 beep \ 2.9 kHz
24 beep \ 2.48 kHz
28 beep \ 2.15 kHz
30 beep \ 2.01 kHz
31 beep \ turned off

Simultaneous LED blinking and fixed (non sweeping) frequency beeping is possible.

Nice!

Silencing should work by resetting the BEEPEN bit:

Code:
: BEEPEN BEEP_CSR 5 B! ;
30 beep  \ 2kHz
0 BEEPEN \ off
1 BEEPEN \ on
: silence 0 BEEPEN ;
silence  \ should be better now


I don't have a beeper connected to my board, so no test.

Frequency generation with the Buzzer output is very limited. Playing a tune wouldn't sound 'nice'.

There is an example for Timer1 and PWM usage on HackaDay here. The SFR addresses can be found here. It wouldn't be difficult to control a servo with it.

I turned the example into a frequency generator.

EDIT1: I used a bit STM8 assembly trickery to get an "unsigned divide by 2". The lowest frequency is now 245 Hz instead of 489 Hz:-)
EDIT2: I figured out how to use the TIMER1 prescaler. The lowest frequency is 16 Hz.

Code:
: TIM1_CR1 $5250 ;
: TIM1_CR1 $5250 ;
: TIM1_CCMR3 $525A ;
: TIM1_CCER2 $525D ;
: TIM1_PSCRH $5260 ;
: TIM1_ARRH $5262 ;
: TIM1_CCR3H $5269 ;
: TIM1_BKR $526D ;

: initTIM1 ( n -- )
  15  TIM1_PSCRH 2C! \ timer prescaler: 16 (1 MHz timer clock)
  1   TIM1_CCER2 C!
  $80 TIM1_BKR C!
  $60 TIM1_CCMR3 C!
  1   TIM1_CR1 C! ;

: relTIM1 ( n -- )
  TIM1_ARRH 2C! ;    \ timer reload value
 
: PWM ( n -- )
  TIM1_CCR3H 2C! ;

\ unsigned divide by 2 using STM8 opcodes
: U2/ ( w -- w/2 )
  \ LDW Y,X , LDW X,(X) , SRLW X , EXGW X,Y , LDW (X),Y
  [   $9093 ,     $FE  C,  $54  C,    $51  C,   $FF   C, ] ;

\ PC3: output frequency n [Hz] with 50% duty cycle (min. 16 Hz)
: Hz ( n -- )
  1000 1000 ROT */
  DUP relTIM1 U2/ PWM ;

\ init timer1
initTIM1

\ set PC3 pitch to "A" (440 Hz)
440 Hz


By the way, "e4thcom" now has an STM8EF plug-in. It works great!
