STVD also packs with a programmer software tool called ST Visual Programmer (STVP). Both are free but a rather difficult to use at first. The best stuffs you can get your hands on at zero costs are ST Visual Develop (STVD) IDE and Cosmic C compiler. We will need an Integrated Development Environment (IDE) and a C-language toolchain. All that we will ever need is the clear concept of each hardware block, their working principles, their capabilities and limitations. We will never need to access registers for any reason as everything is done under the hood of SPL. With SPL, it becomes totally unnecessary to program each peripheral register with meaningless numbers and maintain coding sequence. Apart from these reasons, I chose C language for the fact that STMicroelectronics has provided a Standard Peripheral Library (SPL) that is very easy to use. I don’t want to spend time coding complex stuffs in assembly or other languages. Unfortunately, all the examples I can find are on linux.Just like any other software developer, my choice of language for software development is C language. Although not sure if that program is designed to work with the V3SET in the first place. I found an application installed with STVD that's supposed to 'upgrade' (update?) my LINK with the latest firmware - it said the data on my link is corrupted. Tried both STVD-lite-programmer and STVP - both complained about not being able to communicate with the application (pretty sure this means the chip) via SWIM. Once I got something that builds fine, I tried to flash it into the chip. Also code is full of typos, which is nearly fatal for someone who isn't an embedded-c developer like me. It's amazing how low level it gets sometimes and then just totally skips over stuff. I followed the 'embedded-lab' guide which looks a little better than it actually is.

Spent 9 hours yesterday (20:00 - 05:00am!) trying to get started. Here are some test and example programs, ready to compile with the libaries and write to flash: Here is a PWM controller project for a motor: Here is a water tank level sensor using ultrasonic rangefinder: Feel free to browse the code, and use whatever you like. It also has a support library for the STM8S003 W1209 thermostat, which has three buttons, a 3-digit display, a temperature probe, and a relay. The libraries have support for many input and output devices, such as keypads, LCD, and LED modules, binary/decimal conversion, PWM/servo control, ultrasonic rangefinding, UART. Most of it is for STM8S103 or STM8S105, but the STM8S003 is so close, they will work fine. I have a nice ecosystem of STM8 libraries, sample/example programs, and projects on github. I use the free SDCC (small device C compiler) and ST-LINK V2 and stm8flash to program the chips.
