Re: TFT LCD on Nucleo64-F303 + problems...

Could your share your full example and also the modified library.
This could be fine to see how you do exactly.
This could be fine to see how you do exactly.
so first hardware: (was) Nucleo64 F302R8 ; but shit..small flash (didnt realize, when i ordered this. ) so need bigger,
for the design of : LISA (Loudpeaker Impulse Spectrum Analyzer ) , with FFT and a TFT display , mobile running from a LiPo cell.
ok, so first found a F303RET on aliexpress at 3.20 € , incl. postage. ok, removed F302 and now is: Nucleo64 F303RET ! 500KB flash, ok.
TFT (also from ali, about 7 € ) is 400 x 240 pix , with ST7793 controller ;
to get TFT running, the Mcufriend lib need mod, write timing was to fast ( 15ns write puls...TFT shows nothing.)
so with help from David, who made the lib, now good timing; TFT works also with overclocked 96MHz cpu clock (at 120MHz game over.)
this is the modified part, in mcufriend_shield.h :
Code: Select all
#elif defined(STM32F303xE)
#define WRITE_DELAY { WR_ACTIVE2; } //for alfsch1 was : 2 #define WRITE_DELAY { }
#define READ_DELAY { RD_ACTIVE8; } //thanks MasterT
#define GPIO_INIT() { RCC->AHBENR |= RCC_AHBENR_GPIOAEN | RCC_AHBENR_GPIOBEN | RCC_AHBENR_GPIOCEN; \
/* AFIO->MAPR |= AFIO_MAPR_SWJ_CFG_1; */ }
#define PIN_OUTPUT(port, pin) PIN_MODE2((port)->MODER, pin, 0x1) //thanks fpiSTM
so with help here from fpiSTM , i could get the F303 ADCs run at their native speed and 12bit , of course.
attached : program , at actual state (running, test graphics and simple ADC input + FFT spectrum test.)
+ touchlib , mod for HAL ADC using
+TFT lib, MCUFRIEND_kbv.cpp, mod is timing in mcufriend_shield.h
+ the mysterious opt file
-> in zip file, because forum refuses some files to upload, ie XX.ino seems not allowed (you should change this...
