The issue is that these boundaries should be changeable, since different chars will have different pixel width.
There are two ways of doing this - all capitals have same width and all non-capital...
The best I can think of is shifting & bit masks. If you want to use bits 2 through 5, create a generic temporary variable to put the interim result. Right shift it to put the 1st needed bit at the...
Hello.
I'm upgrading my ST7920 "library", so letters can have variable width, for better visual appearance.
For this purpose, I plan to have single, screen-wide bit array, in which I will write the...
Not yet, but will do. Measure what, I2C clock frequency?
Tried modifying code in a way, that only that part of screen is redrawn, which is being updated. For some uses it does helps, but not always.
Have you measure what clock speed you're getting?
Standard "high speed" I2C clock is 400kHz, maximum clock speed of a Microchip 24C256 when run at >2.5V is 1MHz.
SPI-interface flash chips usually...
Good.
So I have to "learn" to use SPI eeprom 1st, and then use MSSP :)
By the way, if I leave current setup as is - using I2C, but use PIC running at say 32mhz (instead of current 8mhz), will this...
No.
SSPBUF is the Synchronous Serial Port Receive Buffer/Transmit Register. It's the name of register to/from which you write/read whatever gets shifted out.

Well, I don't see anything to be slow at 8mhz, except I2C :D
