It is saved in XML format (.vpc file extension), as simple as possible, but it already has 817 lines of text. Writing the procedure to load all those values will be a little nightmare... if the XML library I use can handle that... So the progress is:1. Open project: underway;2. Save project: complete;3. Save project … Continue reading The project can be saved

Short video presentation of VPC features – with poor sound
Well, if you can endure the bad quality of the sound, you can have an idea about what this program can offer right now regarding the configuration of an STM32 microcontroller using the SPL driver/library. And take note of my level of spoken English 😛 ...
Some needs arised …
... during the video presentation (see previous article):1. The ".json" files needed an upgrade due to some new modifications in version 1.30.2 of Visual Studio Code. Instead of chasing VSCode, I try to identify variables that are consistent (contradiction?) throughout versions. This way, the new modifications won't affect older versions.2. VSCode has an Arduino extension … Continue reading Some needs arised …
Installing and using VPC – first video presentation
Well, there will be no audio for now. But a lot of text and action like in the first muted movies. After this one, other filmed projects will follow.
We have SPI and ADC peripherals
- we have SPI1, 2 and 3, conform with SPL library (still, only master for now);- we have ADC1 peripheral and now pins can be selected as ADC_INx channels;- a function to read the ADC1 values, in spl_library folder;- small code optimizations here and there...Code committed in the repository. What next? Modify the I2C code … Continue reading We have SPI and ADC peripherals
New "things" added…
I've added a new pin function, "ADIN" that manages the ADC input channels, a proper initialization function for ADC1, an with a status LED on the main window, and an "ADC1 Setup" window.I've also added an ADC reading function in "my_soft_adc.h" header from "spl_library" folder. Not yet committed in repository because I am not ready … Continue reading New "things" added…
Closer to SPL library…
I redesigned SPI(1,2,3) setup windows to reflect the elements from SPL library. As things are in CubeMX, just creates confusion and anyway, there is no need of a CubeMX clone. VPC is a visual configurator for projects that still use the old and battle tested SPL library. I2C might follow (in redesigning the interface) but … Continue reading Closer to SPL library…
NVIC priority sorted out.
Is done for the functionality I intend to have for version 1 of VPC (TIM6 and 7, USART2, UART4 and 5, I2C1 and 2, SPI1, 2 and 3, and all GPIO EXTI). It generates code for NVIC priority and sub-priority (with value validation regarding the Priority Group selected) inside the initialization functions of the peripheral … Continue reading NVIC priority sorted out.
NVIC Priority
Update: Changed my mind, I'll give the user full control as there is now a function that validate the values of the priorities and sub-priorities regarding the priority group selected.Hint: Project Settings window has settings for Priority Groups and for the priorities of the pins set as EXTI. Priorities for the "system interrupts" (as SysTick_IRQn … Continue reading NVIC Priority
Weird… OneWire protocol problems using SPL driver
I have a OneWire protocol library for a DS18B20 sensor, that works ok on PIC and AVR, and even on STM32 micros when using LL driver. I converted the library for the SPL driver and... it trows a "bad data" error!The code written for LL driver works ok. So I thought that my my_delay_us function … Continue reading Weird… OneWire protocol problems using SPL driver
