Yes you where right inmarket.. I have it working now, you don’t do anything with the spi in int board but you do all spi work in acquire bus. Below is my board file for 2 ILI9341 displays running on a STM32F1 via spi. It my help others as an example. #ifndef _GDISP_LLD_BOARD_H #define _GDISP_LLD_BOARD_H //**** ILI9341 on SPI1.

I think that what I am doing .. and sorry yes both displays use the same controller. I have set the following in my ugfxconf.. #define GDISP_TOTAL_DISPLAYS 2 #define GDISP_TOTAL_CONTROLLERS 1 #define GDISP_PIXELFORMAT GDISP_PIXELFORMAT_RGB565 My board int looks like.. static inline void init_board(GDisplay *g) { (void) g; //Set up the pins.. palSetPadMode(GPIOB, 0, PAL_MODE_OUTPUT_PUSHPULL);//cs 2 palSetPadMode(SPI_PORT, CS_PAD, PAL_MODE_OUTPUT_PUSHPULL);//cs 1 palSetPadMode(SPI_PORT, SCK_PAD, PAL_MODE_STM32_ALTERNATE_PUSHPULL); palSetPadMode(SPI_PORT, MISO_PAD, PAL_MODE_STM32_ALTERNATE_PUSHPULL); palSetPadMode(SPI_PORT, MOSI_PAD, PAL_MODE_STM32_ALTERNATE_PUSHPULL); palSetPadMode(RESET_PORT, RESET_PAD, PAL_MODE_OUTPUT_PUSHPULL ); palSetPadMode(DNC_PORT, DNC_PAD, PAL_MODE_OUTPUT_PUSHPULL); switch(g->controllerdisplay) { case 0: //Set pins. palSetPad(CS_PORT, CS_PAD); palSetPad(RESET_PORT, RESET_PAD); palClearPad(DNC_PORT, DNC_PAD); break; //Start SPI1 with our config. spiStart(SPI_DRIVER, &spi_cfg); spiSelectI(SPI_DRIVER); /* Slave Select assertion. */ case 1: //Set pins. palSetPad(GPIOB, 0); palSetPad(RESET_PORT, RESET_PAD); palClearPad(DNC_PORT, DNC_PAD); //Start SPI1 with our config. spiStart(SPI_DRIVER, &spi_cfg2); spiSelectI(SPI_DRIVER); break; } } But when I draw to each display only the second display works.. I am switching between displays like so.. coord_t displayA,displayB; displayA = 0; displayB = 1; gdispSetDisplay(gdispGetDisplay(displayA)); ///Do some drawing This does not show gdispSetDisplay(gdispGetDisplay(displayB)); ///Do some drawing This does show

Hello all, Can some one please just help me with my multiple display set-up. I understand the basics of using the multiple displays from the examples but how do I set-up my board file as the only difference between the two displays is the chip select (SPI). Thanks.

Hello, Just having some trouble displaying a custom font can someone please test it for me? userfonts.h.zip

Hello all, I have a working spi SD card setup using gfile. What I want to do is have a file on the SD card with some settings (numbers) and have my code read the file and then have the setting number applied to an int. How would I best go about this? Thank you.

I have fixed the error by enabling #define GFILE_NEED_STRINGS TRUE #define GFILE_NEED_PRINTG TRUE in the gfxconf file.

Hello, I am trying to use the stdio with ugfx as I need sprintf. I have updated my stdio file to fix the compile errors but now I get this error went I use sprintf undefined reference to `snprintg' How could I resolve this? Thank you.

I got it all working. Thank you very much.

Hello, I have got my sd card working under chibios (I can read and write). Now how do I display an bmp file that is on that sd card? I have the basics for displaying images down just don't know how to open image from the sd card. I will be grateful for any help. Thank you.

Is it safe to assume that the fsmc is working? Where should I start to look to fix it. Thank you

Hello, I have just got hold of a tft1p4705 TFT with an D51E5TA7601 driver ic I was just wondering if any one has played with one of there before? Thank you. Here is a link to the driver ic datasheet. https://drive.google.com/file/d/0B_B2fQCYwJRiNnpzcWxqeldoZHM/view?usp=sharing

Hello, I have been trying to get a large number (50+) font working for use with a temperature sensor but I am having some problems. I have userfonts working but only at a font size of 5 as soon as I try to go for the larger sizes the userfont will not work. I have also filtered for just numbers to reduce the size in case that was the problem but no luck. Is there a limit on the font size that I can use? The font I am currently trying to use is DejaVuSansMono. Any help would be great.

Very nice !! :shock: Thank you!

Wow that is a big difference. Thanks for cleaning up the code I to can run SPI_BaudRatePrescaler_2 now. My setup is also running about the same speed as your ugfx setup. Thank you.
