RadASM 3.0.1.0 for STM32F103C8T6 MCU (Blue Pill)

[KetilO]

Some time ago I bouth a 4.0 inch LCD panel on eBay.
The panel has the ST7796 driver chip.
More info at: http://www.lcdwiki.com/4.0inch_SPI_Module_ST7796

I finally found the time to test it.
Included is the source code and how to connect it to the STM32F103C8T6 (Blue Pill) .
An image is also included.

Same as abow but for the STM32F401 (Black Pill).
It shouldl also work with the STM32F411 (Black Pill).

I will for shure create somthing useful with this MCU / LCD.

Educational experiments tool version 3.

Version 3      2023-01-16 Bugfix
                    Fixed bug in LCD.c LCD_WR_REG where
                  the program could hang in this function.
                  Speed optimized LCD.c LCD_DrawIcon.
                  Changed main.c SysTick handler to generate
                  interrupt every second.

The above posts download and Sourceforge  has been updated.

Hello Ketil;
Does the driver IC matters while using 4.0" lcd screen? For example can I use ILI9486 with your sources?

[bluedevil]

How much volts you need for reed relays: 5V, 12V or 24V

Hi

"Does the driver IC matters while using 4.0" lcd screen? For example can I use ILI9486 with your sources?"
No, the LCD.c file needs to be modified to match the  ILI9486 .

"How much volts you need for reed relays: 5V, 12V or 24V"
5V

Hi,

I am currently working on a project using the STM32F103 (blue pill) where you connect
it to yor PC via USB. The PC will then replace the LCD screen.

Included are all the sources for this early version.

Sounds like an outstanding project. Makes me want to get back into making electronics projects of my own again...

Ketil; thank you for your answers.

I have questions on the semi-conductors: TLE2072, TL074, TL712 and LM311. You have mentioned the base names but did not share the exact names. There are several postfixes for those transistors; like: TLE2072ACP, TLE2072IP, TLE2072CP and goes on...

I have found these on Al-i-express; are those compatible?

TL074CN
LM311DR
TLE2072CP
TL712CP

Or can you share the full names(including postfixes) of transistors. Thank you.

Hi bluedevil

The only important thing is that it is a PDIP package and not the SOIC.
Some postfixes are for ceramic or plastic and lead free

Example:
TLE2072CP (PDIP-8) - OK
LE2072ACPE4 (PDIP-8 lead free) - OK
TLE2072IDR (SOIC 8)- Surface mount, not ok

OK Ketil, taking into account your directions, I am goıng to buy those semiconductors:

TL074CN
LM311P
TLE2072CP
TL712CP

I understand that these are compatible for your projects.
