Re: TEK 4010/4014 Vector Graphics terminal DEMO

Regarding doing fills.
Maybe we can bring Tek to fill out a rectangle if we write a "space" character with the desired color and dimension at the desired coordinate.
Of course, this will only work for horizontally and vertically aligned fills.

Re: Getting Eclipse to work? A proper guide?

Don't upgrade to oxygen only use neon 3.

I would recommend to use PlatformIO, then export project to Eclipse. It works.

Re: STM32F103C8 & TFT (ili9325)

1. faster reading from card If you are using the SD card only for reading, then you could use the SdFatEX class (search the SDFat lib for that information, and/or the forum) or use at least a 4kB buffer. http://stm32duino.com/viewtopic.php?f=51&t=2034&p=27982&hilit=sdfatex#p27982 2. parallel process...

I am almost sure that I tested the BMP example reading a file from SD card, but I will check it again.

Re: Use STM32F103C8 with TFT 320QVT 9341

If the 401 has FSMC, then you could use the actually available Arduino_STM32 core for 407, it has the FSMC adapted for 16 bit parallel access LCDs.
Search the forum for FSMC.

Re: Blue Pill that kills

I would bet:
1) the 3.3V regulator is dead. Replace or remove it.
2) the STM32 chip is dead (less likely, they are really easy to destroy)

Re: Nucleo F103-RB and slow TFT Refresh

Have you measured the run-time of each function in your main loop?
How often interrupts are generated?
How much is the TFT SPI clock frequency?

Re: STM32F103C8 & TFT (ili9325)

OK, so if graphicstest runs well, setAddressWndow() sould also be ok, then it most probably has to do with the BMP example.

Better said, a function involved by the BMP example, but not involved in graphicstest, is probably the reason.

Re: STM32F103C8 & TFT (ili9325)

Your LCD pin settings in the sketch are not relevant. Only what in the "Adafruit_TFTLCD_8bit_STM32.h" header file is set, is relevant. So please set there the LCD pins (and the mask values as well). Also, don´t forget to allocate the LCD_RST pin, it is important that the LCD get reset. To be sure th...
