Re: Suggestions for TFT shield for mini/pills etc.

Hi Roger, that is exactly what I am trying to design, display one side of the board, 'pill' on the other, access to all pins. I have today finished and ordered a design to my specs which I will publish later once it has arrived and been tested.I just wondered what other people may want.

Re: Remap PB2

SteveStrong It still no workee! It reports the following; TFT LCD test TFT size is 240x320 ID: 0 *** Unknown LCD driver chip: 0 So, I was looking at Adafruit_TFTLCD_8bit_STM32.cpp and I wondered about two functions uint16_t Adafruit_TFTLCD_8bit_STM32::readID(void) { if (readReg32(0x04) == 0x8000) { ...

Re: Remap PB2

Genious! It was so much easier to move all the pins across to PB5..PB9 and redefine in the sketch and you, I get sensible results No to edit the hearer file and try the graphics test .... I may be some time Read Registers on STM32duino controllers either read as single 16-bit e.g. the ID is at readR...

Re: 1024 point fft - results not as expected

@Pito, thanks for your reply. I know a rubbish spectra when I see one, Ive been lookint at FFT spectras for the last 25 years (although I am newbie in coding FFT). In the end, I scrapped this and started with a blank sheet. This is my code and it seems to work. So, its reading 1024 samples at 391uS ...

Re: Remap PB2

OK, I'll give you that one SteveStrong, that was an accident, they were supposed to be in order on the pill and twisted on the tft. however, now I have put that right, I still get the same results from the id_regread sketch!

Aaarghhhh!

Suggestions for TFT shield for mini/pills etc.

Guys, I am designing a shield to make my work with the TFT boards easier. I want to put the eagle files etc here so anyone can get them made. There will be a set of sockets on the underside to attach to the UNO type 8 bit + SPI TFT shields. The top side will have 2 X 20 pin sockets to accept the 'pi...

Re: Remap PB2

UPDATE

I also connected the shield to a CZ miniSTM32F103VEK board using the same pins, Data on A0-A7 & CTRL on B3-B7.

I got the exact same result.

Re: Remap PB2

WP_20170223_20_17_07_Pro.jpg SteveStrong, Thanks for your reply (and your patience) So, I ran the code on the STM32 mini board which was connected as in the pic above. The pin settings were as follows; #define LCD_RST PB8 #define LCD_CS PB7 #define LCD_RS PB6 #define LCD_WR PB5 #define LCD_RD PB4 #...
