I had a problem where during compilation with stm32cubeide there was "multiple definitions of 'image' " error. Solved by moving "uint8_t image[(128 * 64)/8];" from "ST7920_SERIAL.h" to "ST7920_SERIAL.c". Now it works fine in proteus 8. IDK about the cause though. I checked for repeating definitions and as far as i know "ST7920_SERIAL.h" wasn't being #included multiple times.

Good work but I prefer the 3 lines to send bytes to the display and use it for some saving current sensitive projects.

how fast is this display? for sending data, in example: encoder data distance 1 to the distance 2

Why not using HW SPI. The STM32 is full of on chip peripherals to unburden the CPU. Bit banging is not the way.

SPI have some issues when it comes to the displays. I personally have always found SPI unreliable somehow... personal opinion though

Thanks a lot, but I have a question ... how to write on lcd with smaller font ?

@ControllersTech 4 жыл бұрын

By default, the custom fonts are not supported. If u still want to change the font, u have to use the graphic mode and control each line somehow. Not impossible, but kinda hard..

Hello sir, I know that probability to get response is almost 0, but I still want to ask about one very important thing. I wanna display bitmap image which size is 87x32 pixels (const char size is 348, not 1024), and wanna that image be shown from x=50, y=10 coordinates on display. How can I modify your ST7920_DrawBitmap function to achieve this? In my opinion it's the most important thing, because when we do some real project we would rarely want to display whole 128x64 bitmap, we need to be able to display some smaller symbol in the specific place on display.

can we print float or integer?

@ControllersTech 4 жыл бұрын

Yes we can. Integer can directly be converted to characters using sprintf. To convert floating values into characters, you need to add few things in your IDE. Google that for the IDE you are using.

It works, if you use stm32 as arduino. There is a video about it on the channel. But don't expect everything to work.. better buy Arduino for that

You did not do the SPI structuring in the code, did you only perform the operations with the output pins? There is no SPI_init configuration in main.c file

Yes. I am going to release another video on it soon using the SPI.

Then, we can control the ST7920 using 4 GPIO output pins as in this video without using SPI, right? Also, there will be a cable length of 2 meters between the microprocessor and the ST7920. Do you think it will be a problem for communication? After all, you control it directly with the output pins?@@ControllersTech

@ControllersTech 6 ай бұрын

The output pins are generating the SPI signals. So in a way SPI is still being used.

In this video, you didn't have custom font and this is my need that i use custom font in this project. Please explain about custom font. Thank you

@ControllersTech 4 жыл бұрын

Haven't really thought about it. Check the datasheet, it should be mentioned in that or look for some examples and see what register to use for the custom fionts.

@ControllersTech 4 жыл бұрын

Looks like st7920 doesn't support custom fonts directly. If u want to use them, you have to use the graphic mode. And control all the pixels individually. That's a lot of work.
